The most harmful substances in cosmetics. Prohibited raw materials What substances should not be contained in cosmetics

cosmetologist

Paying attention to the small print at the bottom of the jar, and not to its name, is not at all a sign of boring. We study the composition of cosmetics and find out which components should not be in it, and what will happen if they are still on the list of ingredients. Our expert is Marina Vereshchatina, beautician, specialist in natural and organic cosmetics, training manager of the Weleda brand.

SLS / ALS / SLES

These letters can be used to calculate the most common surfactants in traditional cosmetics - surfactants that form abundant foam. They are obtained from petroleum products, and manufacturers are respected for their cheapness.

The most common surfactant is SLS. It is present as a fat solvent in most cleaning products, from baby shampoos to automotive products. And wherever it turns out, it shows its aggressive cleaning properties. The skin is known to be covered with a natural hydrolipidic mantle, which is extremely important for the health of the epidermis: the mantle protects it from external irritants, affects elasticity and prevents water loss. If you use a cleanser with aggressive foaming agents, the hydrolipid layer will be washed out, and that's it, a feeling of dryness and tightness, and sometimes dermatitis. SLS and similar components worsen skin conditions with atopic dermatitis and neurodermatitis.

Often, cleansers with cheap surfactants violate water balance fatal and the skin becomes sensitive

If there are synthetic surfactants in the shampoo, it will cleanse the scalp too actively, depriving it of its protective resources. To compensate for excessive dryness, the body will begin to produce sebum in unprecedented volumes, and then we are tormented by the question: why do I have to wash my hair every day? But the greatest harm SLS / ALS can cause being in the composition of the toothpaste. Surfactants violate the microflora of the oral cavity, and this is the reason for the sensitivity of the mucous membrane and aphthous stomatitis.

Mineral oil

It can hide under a dozen names, depending on the state of aggregation - solid, liquid or gel. It seems to us impossible to remember all the variants of the names, so the main thing is not to forget that the composition should not contain the words mineral and paraffin. Nevertheless full list variations of the names of mineral oil looks like this: mineral oil; paraffin oil; liquid paraffin; paraffinum liquidum; light liquid paraffin (paraffinum liquidum); paraffinum perliquidum; oil mist; oil mist (mineral); mineral oil mist; mineral; mineral syrup, mineral oil hydrocarbon solvent (petroleum); mineral oil (saturated paraffin oil); petroleum; white mineral oil; white oil; white mineral oil mist; hydrocarbon oils; petroleum hydrocarbons; paraffinic; petroleum jelly and soft paraffin.

Mineral oil itself is a very cheap ingredient, but this does not prevent cosmetic brands from adding it to budget products, to luxury products. Mineral oil is essentially what we put into a car engine, the same substance that we are offered to take care of, including for baby skin. How does oil work? The synthetic covers the epidermis with an occlusive film and thus prevents the removal of metabolic products. This is where the metaphor "skin does not breathe" has a direct meaning.

Nevertheless, our expert admits the presence of this component in some tools. But we are not talking about daily care, but about a single application: for example, when mineral oil is part of a therapeutic ointment.

Aluminum salts

Aluminum chloride, Aluminum chlorohidrat - many have now learned the main active ingredients of antiperspirants and are absolutely right. How many attacks the poor antiperspirants have withstood, and the claims against them are not groundless. They work at the expense of aluminum salts: they block perspiration by blocking the sweat glands, which is not physiological in itself. After all, sweating helps to remove toxins and toxins from the body, and provides thermoregulation.

Aluminum salts accumulate in the body, and this is especially inappropriate for people with diseases of the excretory system, liver, and kidneys. There are no evidence-based studies on the carcinogenic effect of aluminum salts, and it may be a matter of time. It is not for nothing that, for example, in the United States, many antiperspirants are already being made without these components.

Propylene glycol

Often found in synthetic cosmetics and antifreeze. This product of petrochemical synthesis makes the cell membrane more permeable, creates the effect of imaginary moisture, and displaces its own moisture from the skin. But there are more cruel ones side effects: contact dermatitis, increased dryness of the skin with eczema and atopic dermatitis.

Preservatives

According to our expert, the most harmful of these is Formaldehyde. The mere fact that it is used in embalming is already alarming. Formaldehyde is a cheap component, but with exceptional preservative properties. Hence such a strong attachment to him among the manufacturers of conventional cosmetics. This is how professionals call the most ordinary products, they are sold in ordinary stores, they have a low cost and shelf price, the traditional composition is glycerin, lanolin, mineral oil, etc. Fortunately, in recent years, formaldehyde in its pure form has been used less and less, the reason - its toxicity.

However, some substances are capable of releasing it under certain conditions of storage and transportation. Therefore, after making sure that there are no parabens in the product, once again go over the composition for formaldehyde releasers. In cosmetics, these toxic substances appear under the names: 5-bromo-5-nitro-1,3-dioxane, 2-bromo-2-nitropropane-1,3-diol, DMDM ​​Hydantoin, Quaternium-15, Sodium hydroxymethylglycinate, Imidazolidinyl urea ...

Raw material requirements

In the cosmetic industry, various types of raw materials are used: vegetable oils, waxes, herbal extracts, vitamins, antioxidants, silicones, enzymes, etc. The need for a careful selection of raw materials for the preparation of perfumery and cosmetic products is dictated by the significant environmental burden that our skin and hair bear. In connection with the introduction of a huge number of chemical compounds into production, cases of undesirable reactions to cosmetic products have become more frequent: allergic, contact dermatitis, photodermatitis, etc., therefore, the first requirement for cosmetics is its safety. It's not so bad if a cream or shampoo is ineffective. It is much worse when they cause unwanted reactions, accelerate aging, damage the skin or hair. All raw materials in the composition of cosmetics must be safe, must not contain harmful impurities, substances damaging skin cells, allergens, microbes and their toxins, products of peroxidation of oils, preservatives and aromatic substances that destroy the epidermal barrier, heavy metals, nitrates, radionucleotides. All components must be compatible with each other and must not cause antagonism.

Harmful raw materials

The Independent International Society of Cosmetic Chemists issues lists of substances excluded from the list of approved cosmetic ingredients at least twice a year. If any information is found about the adverse effects of their use, then they are included in the "black list" of ingredients prohibited in cosmetics.

Below is a list of the main ingredients used in forbidden or limited in most countries.

Amber musk as a fragrance can be used in perfumes, as well as in any cosmetic preparations. It causes photosensitization of the skin, is neurotoxic, i.e. is capable of affecting the nervous system: sharp headaches appear and what experts call a violation of behavioral reactions: severe irritability, deterioration of mood, impaired coordination of movements, etc.

Vinyl chloride - main component of aerosols, solvent. Well absorbed through the skin. Possesses neurotoxicity. Carcinogen.

Hexachlorophene - preservative. It can be used in any cosmetic products, most often in emulsion creams. Well absorbed through the skin. Possesses neurotoxicity.

Diocan - carcinogen. Especially dangerous for the liver, it penetrates well through the skin. Contained in some ethoxylated surfactants, which are referred to as PEG on the label. May be found in shampoos, shower gels, bath foams and other body and hair cleansers.

Nitrosamines - carcinogens. They are especially dangerous for the liver, they penetrate well through the skin. Nitrosamines are not specifically included in cosmetics, but in preparations containing amines (triethanolamine and other emulsifiers of this series), they can be formed if the shelf life and production technology are violated. In addition, the formation of nitrosamines can be triggered by the presence of ingredients with impurities in the formulations.

Substances from the amine group can be used as emulsifiers in any cosmetic product. Most often they are included in the composition of nourishing creams. These substances can be recognized on the label at the end of amin.

Zirconium derivatives used in cosmetics in aerosols, hair products. Have a toxic effect on the lungs.

Mercury and its derivatives used in whitening and eyelid skin care products. A strong allergen, has a neurotoxic effect, has a tendency to cumulation (accumulates in the body). If derivatives are used, the permitted concentration should not exceed 0.006% in terms of pure mercury.

6-methylcumri It is used as a fragrance and scent fixer in perfumes. Increases the sensitivity of the skin to ultraviolet radiation - up to photodermatitis and severe systemic disorders. Not recommended for use in tanning or sunscreen products.

In order to avoid the appearance of products with hazardous ingredients on sale, our country has introduced an annual certification of cosmetic products and production. You should purchase cosmetic products only in special stores or sections, beauty salons, at professional sales exhibitions - where you can be shown everything Required documents and give qualified advice on the properties and use of certain drugs.

Propylene glycol – for a long time it has been used in cosmetics as a moisturizer for the skin, but now, as a result of research, scientists have found that it is able to dissolve the intercellular cement in the stratum corneum of the epidermis and reduce the adhesion force between corneocytes, resulting in a loss of moisture, and as a result, progressive aging of the skin. Also, scientists have proven that propylene glycol has a toxic effect on living cells.

Sodium lauryl sulfate – surfactant, has a strong detergent and foaming properties. Formulations containing this raw material are dermatologically unfavorable due to their irritating and degreasing effect on the skin. In addition, there is experimental data on the toxicity of this substance. Sodium lauryl sulfate, together with dirt, removes epidermal lipids, which leads to skin irritation, dandruff, and brittle hair.

Do you know that: you can judge the amount of a raw component introduced into the composition of a cosmetic product by the place it occupies in the list given on the package - the closer the raw component is to the beginning, the more it is.

Preservatives

One of the main requirements for modern drugs is their resistance to pathogenic microbes. Most of the cream compositions are excellent nutritional blends that are beneficial not only for skin cells, but also for the development of microorganisms. And since our environment is saturated with various strains of bacteria and fungal spores, in order to preserve the quality of cosmetic preparations, substances called bacteriostatics or preservatives.

Preservatives solve one of the main problems in cosmetics - the problem of protecting products from deterioration and observing their shelf life. By the way, this period, according to international standards, should be 2.5 years.

Another purpose of using preservatives is to kill bacteria and fungi directly on the skin.

The problem is that in order to destroy microbial cells, the preservative must necessarily be toxic, and, therefore, it can be toxic to skin cells. The main negative qualities of preservatives are the ability to deprive the skin of its natural microflora and cause allergic reactions. In addition, many preservatives greatly slow down the skin regeneration processes. And if young organisms are somehow able to cope with this, then for those who are over 35 years old, this is a serious problem, since it leads to progressive aging of the skin. Therefore, preservatives are often called "the main enemies of the skin, which cannot be dispensed with."

Most often, chemically synthesized substances or antibiotics (literally opponents of life) are used as preservatives: nipazol, nipagin, a number of parabens (butylparaben, methylparaben, ethylparaben ...), phenoxyethanol, ethyl alcohol, ionol, oxypyridine, etc.

Dangerous preservatives: formalin (leads to progressive aging of the skin), bronopol (can lead to the formation of mutagenic substances).

Any cream composition contains preservatives, however, advertising brochures and annotations are usually not disclosed about the amount of preservatives used. This can be judged by indirect signs, which have already been discussed, and in this regard, it is necessary to adhere to some rules for the acquisition of cosmetics.

♦ Give preference to cosmetics with a small hole. The wider the neck of the jar, the greater the contact with the environment, and therefore the more preservatives are in the cream.

♦ Pay attention to the expiration date and storage conditions of the drugs. The longer the shelf life and the higher the storage temperature, the more preservative is added to its composition.

♦ And most importantly, keep the cream compositions in a cool place, tightly closed.

NB: The safest are undoubtedly natural substances found in nature in some plants (sodium benzonate, salicylates, vitamins E and C ...). Widely known for their bactericidal properties are propolis (bee glue), extracts of eucalyptus leaves, bird cherry, birch, black currant, pine bark extract, seaweed extract, many essential oils.

The introduction of these substances into the formulation allows you to reduce the concentration of preservatives and make the cream safer for the skin, so most likely they are the future of cosmetics.

But natural preservatives also have their drawbacks - too mild bacteriostatic action, requiring the use of sufficiently high doses, and narrowly focused specialization (blocks the growth of bacteria, but does not prevent fungi from living, and vice versa).

Every day we use dozens of cosmetics to preserve youth and have a flawless look. However, we rarely think about what this or that cosmetics consists of, whether it is really effective and how safe it is for our health. Therefore, today we will tell you what harmful components cosmetics can damage our health.

Harmful cosmetics: additives that are not safe for health

Shampoo, shower gel, soap, bath foam - cosmetics that are in the arsenal of every woman. However, when buying them, rarely does anyone think that they can cause serious harm to human health. The most harmful substances in hair and body care cosmetics:

• Sodium Lauryl Sulfate (SLS) - one of the most dangerous preparations that contain detergents. Some unscrupulous manufacturers try to disguise it as natural, saying that this component is obtained from coconuts. This ingredient does help remove oil from hair and skin, but at the same time leaves an invisible film on their surface, which contributes to the appearance of dandruff and hair loss. In addition, it can penetrate the skin and accumulate and linger in the tissues of the brain, eyes, and liver. SLS belongs to active carriers of nitrates and carcinogenic dioxins. It is very dangerous for children, since it can change the protein composition of the cells of the eyes, it causes a delay in the development of the child;
• Sodium Chloride - used by some manufacturers to improve viscosity. However, it can irritate the eyes and skin. In addition, salt microparticles dry out and severely damage the skin.
• Coal Tar - used for anti-dandruff shampoos. Some manufacturers hide this component under the abbreviation FDC, FD, or FD&C. May cause severe allergic reactions, affects the nervous system. In European countries, this substance is prohibited for use;
• Diethanolamine (DEA) - a semi-synthetic substance that is used to form foam, as well as to thicken cosmetics. Dries out skin, hair, causes itching and severe allergic reactions.

Decorative cosmetics almost all of them contain harmful and toxic substances. When doing morning makeup, we never think about the fact that lipstick, mascara, shadows, tone cream and powder can cause irreparable harm to our health.

Content

Before you buy a jar of miraculous cream or shampoo, carefully check their composition! Some components should not be in the composition of cosmetics, since they are not only useless, but often harmful.

Numerous beauty ingredients that are part of branded cosmetic products have an expensive production technology, require large material and physical costs, and a priori cannot be cheap. A jar of face cream with black caviar will never be cheaper than the delicacy itself.

There is a widespread belief that popular brands produce extremely high quality cosmetics. It seems that if a cosmetic concern is famous, produces large volumes of products, then it produces high quality cosmetics. But advertising requires a lot of money, which could be spent on improving the composition of cosmetics! Paying a celebrity to introduce a product, paying for an advertising agency, or running a large-scale promotion costs a lot of money. When buying advertised cosmetics, you spend more than half for advertising, beautiful packaging, services of designers and intermediaries. Thus, the cost of the contents of a jar of cream of a well-known brand and a little-advertised company is almost the same.

Good for the skin ...

Jojoba extract. In modern cosmetology, the jojoba plant is often used for face and body lifting. This ingredient is often found in lip gloss, shampoos. The homeland of the evergreen jojoba shrub is Tibet, North America. It has an official beautiful name Simmondsia is Chinese, although it has nothing to do with China. In cosmetology, nuts from this shrub are used, they look like peach bones. Jojoba nuts are cold pressed to produce jojoba oil, similar to liquid wax. This substance is responsible for the elasticity of the skin, it is resistant to rancidity.

Jojoba oil is mixed with various essential oils to create a cream. The magical effect of such a cream is due to the content of amino acids, which are close in composition to the wax esters of sebum. This cream recreates collagen in the skin, has a bright anti-aging effect, makes the skin glow and youthful. The cosmetic value of jojoba has been scientifically proven.

Pearl shine. Pearl extract is often used for cosmetic and pharmaceutical purposes. Pearls specially grown in lakes and rivers are turned into pearl powder, which is 90% calcium carbonate. Pearl powder contains glutamic, aspartic acids, glycine, alanine, methion. For the first time, the healing properties of pearl powder were appreciated in China and Japan. Now pearl powder is also used by pharmaceutical concerns, adding it to the composition of wound healing ointments. With osteoporosis, weakened immunity, it is recommended to take inside dietary supplements based on pearl powder. Pearl extract promotes deeper penetration of other active substances into the layers of the skin. Sometimes cosmetic products contain biogold and diamond chips as an additive to the main ingredients.

Silk shampoo. In the cosmetic industry, silk powder is often used, obtained by grinding the fiber of a silkworm cocoon. Silk powder contains many useful substances: glycine, alanine, serine. As part of the shampoo, these active substances are easily absorbed by the scalp and hair follicles. The skin is moisturized, metabolism is improved, and tissue regenerated. Forming a film on the surface of the hair, they retain moisture and add shine.

Grape seeds. To make the skin smooth, firm, and fight cellulite, grape seed extract is added to cosmetics. By the method of aqueous-alcoholic extraction, it is concentrated, dried and a brownish powder with a pungent odor and taste is obtained. Grape extract contains organic acids, flavonoids, carbohydrates, has an antioxidant, anti-inflammatory, astringent effect, perfectly strengthens the capillaries. It is an excellent anti-cellulite agent that saves dry skin from dehydration.

Green tea. To improve the elasticity of blood vessels, cosmetologists use green tea extract. It contains antioxidants, caffeine, amino acids that tone the skin, give it smoothness and elasticity. Dentists appreciate its antibacterial properties and recommend toothpastes with green tea extract. Caffeine perfectly tones up both internally and externally. After applying the coffee scrub for several hours, you will not leave the feeling of vigor and lightness.

Lotus. Some cosmetics contain lotus extract, a flower of unearthly beauty. It is noteworthy that only 1 kg of valuable powder is obtained from 10 kg of lotus flowers! Flavanoids, alkaloids, peptides and organic acids have an invaluable effect on the skin. Lotus extract will help stop bleeding, whiten skin, get rid of petechiae.

Harmful to skin ...

In the production of cosmetics, in addition to herbal ingredients, components of animal origin and synthetic additives are used. Unlike plant extracts, components of animal and synthetic origin, in addition to benefits, are harmful to our beauty and health.

Mineral oil. This "valuable" product for our beauty is obtained from petroleum products, is used in industry for lubricating parts and engines, in chemical production it is used as a solvent. When applied to the skin, it creates a dense film that not only prevents moisture from evaporating, but also retains toxins, carbon dioxide on the surface of the skin. The skin stops breathing, the process of its renewal is delayed, it becomes dry, lifeless, dull. Such cosmetics can cause acne even in women of middle age!

Propylene glycol. This refined petroleum product is renowned for its moisturizing properties and is widely used in moisturizing creams. Its cost is much less than glycerin, which makes the cosmetic product cheaper. However, propylene glycol often causes allergies, skin irritation, and acne. Why should you avoid it anyway?

• Propylene glycol creates an impenetrable film on the skin, which prevents breathing, nourishing the skin, and contributes to its thinning
• This substance binds fluid, displacing water from skin cells
• Doctors talk about the connection between propylene glycol and disorders in the functioning of the liver and kidneys

Laurel Sodium Sulfate (SLS). No shower gel, shampoo, hair balm, bubble bath is complete without this ingredient. In industrial production, this substance is used in the composition of a liquid for cleaning floors, for degreasing surfaces. It perfectly removes grease from any surface. The world's leading clinics use sodium laurel sulfate as a skin irritant. Scientists have proven that SLS is able to penetrate the human body - the brain, heart, eyes, and accumulate in the liver. Laurel sodium sulfate creates a film on the surface of the skin and hair that is difficult to wash off and irritates. Hair after regular use of such a shampoo will become brittle, dull, fall out, thinner, and dandruff will appear. Manufacturers' claims that their laurel sodium sulfate is natural and derived from coconuts is completely contrary to reality.

Loret Sodium Sulfate (Sles). An ingredient similar to the one described above, which is also often used in the production of shampoos and hair products.
Differs in cheapness, so manufacturers do not save on it. The salt in the sodium sulfate loretta makes it thicker, when in contact with water, a lush, thick foam is created, but has weak detergent properties.

Glycerol. Traditionally, glycerin is considered an excellent moisturizer. This "useful" component of cosmetic products is obtained by combining water and fat, resulting in smaller molecules. The resulting fatty acids and glycerol improve the penetration of cosmetics, does not allow moisture to evaporate from the skin surface. Scientists have shown that if the air humidity in the room is less than 65%, glycerin draws liquid not only from the air, but also from the skin. The skin becomes drier and the moisturizing properties of glycerin are questioned.

Myths about cosmetics

Myth 1: High-quality cosmetics contain special ingredients that are irreplaceable for our beauty.

Collagen. Collagen manufacturers are vying with each other: it moisturizes the skin, improves the structure of the skin, and nourishes the deep layers of the epidermis. Collagen supports the structure of our skin like a mesh frame, making it stay smooth and flawlessly even. With age, everything wears out, and the necessary collagen is destroyed, the skin becomes thinner and wrinkled. So is collagen worth pinning high hopes on?

• Collagen molecules are large, which makes it much more difficult to penetrate into the layers of the skin. Collagen creates a dense film on the surface, preventing the skin from breathing
• Collagen is of animal origin - it is obtained from the skin epithelium of cattle, therefore such collagen cannot be properly absorbed by the skin of the face
• The body perceives collagen injections as a foreign body and rejects it, therefore, to maintain the result, it is necessary to regularly visit a beautician

Elastin. Many manufacturers add elastin to the composition of skin and hair care products. With aging of the skin, elastin molecules cease to retain skin cells, and wrinkles are formed. Elastin, added to anti-aging creams, helps to restore the structure of the skin. In any case, this is what the manufacturers say. But elastin is of animal origin, consists of large molecules and is not able to penetrate the layers of the skin. Elastin, close in chemical composition to human and able to penetrate skin cells, is called desmosin. But its use greatly increases the cost of the finished product, so manufacturers rarely produce cosmetics with "healing" elastin.

Hyaluronic acid... This beauty ingredient can be of both plant and animal origin, it is used to fill in fine wrinkles, as a mask for skin rejuvenation. To achieve results, it is necessary to use a low molecular weight acid - this is how the molecules freely penetrate the skin cells. Therefore injections hyaluronic acid so effective. Creams, masks, lotions contain a high-molecular form of acid, which is unable to penetrate into the deep layers of the skin, but remains on its surface. The content of hyaluronic acid in the composition of cosmetic products is negligible, which refutes their miraculous properties.

Liposomes. Liposomes are artificially obtained closed bubbles filled with water and various fats. Cosmetologists believe that they are able to saturate the skin cells with moisture. Recent studies prove that chemical composition liposomes are identical to the composition with cell membranes, that is, there can be no talk of any rejuvenation. Liposome moisturizers will never moisturize aging skin.

Placenta extracts. The placenta is the shell in which the embryo grows and develops. It feeds through the placenta, and it is believed that the skin of the face will also be able to receive nutrition, beneficial substances with placenta-based creams. But the embryo receives everything it needs through the umbilical cord, and the lifeless placenta itself has no value. The nutritional, anti-aging properties of the placenta are highly questionable, as its composition is difficult to study and control.

Royal jelly. The substance produced by worker bees is collected in hives and endowed with miraculous properties. According to rumors, royal jelly rejuvenates the skin, smoothes wrinkles, saturates it with useful substances. It has been proven that after 2 weeks of storage, the most valuable substance completely loses its "rejuvenating" qualities. For humans, royal jelly is useless, it does not have any special effect.

Before replenishing your cosmetic stocks, it's worth taking a close look at the potential purchase. It is important to remember that in addition to benefits, almost any cosmetic product can also bring harm. Let each new jar of cream, shampoo, lotion bring pleasure and enhance your beauty!

There is no smoke without fire! Let's together critically analyze in which points the author of the list was mistaken, and in which he was right. Write your reasons in the comments!

Note:
list sorted in Russian alphabet.

If the labels on the packaging are made on English language, cm. .

Not all ingredients on the list are hazardous to your health, read the explanations for the specific ingredient.

Unfamiliar words:

Carcinogenic(cancer - cancer) - dangerous and toxic substances that cause malignant tumors.

Mutagenic- dangerous substances that produce changes inside cells at the genetic level, i.e. change the structure of cells.

1,2-Dichloroethene, Acetylene dichloride, Sim-Dichlorethylene - Dioform.

Used in many toothpastes and other teeth whiteners. Damages tooth enamel.

Alkylphenol ethoxylate - Alkyl-phenol-ethoxylades.

Reduces male sperm count by mimicking the action of estrogen. It is widely used in shampoos.

Alcohol, Alcohol - Alcohol.

Acts as a vehicle and prevents foaming. Dries quickly. Synthetic alcohol (as opposed to microbiological) is a toxic, carcinogenic, mutagenic substance that causes adverse reactions in the body.

Albumin - Albumin.

Albumin is the main ingredient in skin-tightening formulations. It is advertised as an anti-wrinkle treatment. The formula contains bovine serum albumin (bovine serum albumin), which dries to film the wrinkles without making them appear as noticeable. Has a negative effect on the skin.

The last time a serious customer complaint was filed was in the 1960s. Both of these drugs were wrinkle removers. The composition contained bovine serum albumin, which, when dried, formed a film over the wrinkles and made them less visible ...

Alpha Hydroxide Acids, Alpha Hydrax Acids - AHA's.

Old cells are exfoliated from the surface of the skin, after which only fresh young cells remain on it. The skin looks younger and less wrinkled. By removing the outer layer of dead cells, we also remove the first and most important protective layer of the skin. In this case, harmful environmental factors that contribute to skin aging penetrate into it faster and deeper. As a result, the skin ages prematurely.

Aluminum - Aluminum.

It is used as a color additive in cosmetics, especially in eye shadow, as well as in deodorants and antiperspirants. Harmful.

Flavors - Fragrances..

Aromatic additives for most cosmetic preparations. They contain up to 1000 synthetic substances, which are mostly carcinogenic. May cause headaches, dizziness, allergic rashes, skin discoloration, severe coughing and vomiting, and skin irritation. Clinical observation proves that aromas can affect the central nervous system and cause depression, irritability, etc.

Acetamide, Acetic Acid Amide - Acetamide MEA.

Used in lipsticks and blushers to retain moisture. It is a poisonous, carcinogenic, mutagenic substance.

Benzene, Aromatic Hydrocarbon - Benzene.

Benzene is a bone marrow poison. In combination with other components, it is widely used in cosmetics. It is a poisonous, carcinogenic, mutagenic substance.

Bentonite - Bentonite.

Bentonite - 1. Highly plastic clay, 2. Grade of bleaching clay. It is a natural mineral that is used in masks, powder and other cosmetics. It differs from ordinary clay in that it forms a gel when mixed with liquid. Bentonite is thought to be able to draw out toxins.
It is a porous clay that quickly absorbs moisture from the skin. Forms gas-tight films.
Intensively retains toxins and carbon dioxide, preventing skin breathing and excretion of waste products. Strangles the skin by cutting off oxygen. Bentonite particles can have sharp edges and scratch the skin. Comedogenic. Experiments on mice have shown high toxicity.

Biotin, vitamin H, vitamin B7, coenzyme R - Biotin (Vitamin H).

Biotin (Vitamin H) is an exotic ingredient touted as essential and beneficial for skin and hair care. Lack of this vitamin has been associated with oily skin and hair loss in rats and other experimental animals. However, human hair is different from animal hair. Biotin deficiency is extremely rare, and therefore can be considered a completely useless supplement in cosmetic preparations. Moreover, the molecular weight of biotin is too large for it to penetrate the skin.

Bronopol, 2-bromo-2-nitropropane-1,3-diol, BNPD -Bronopol.

Forms nitrosamines, which are carcinogenic. The most expensive Chanel cosmetic line uses this ingredient. Even shops specializing in natural cosmetics sell products containing bronopol, although there are many other natural substitutes. It is very dangerous.

Butylated Hydroxyanisole, E320 - Butylated Hydroxyanisole (BHA).

Butylated Hydroxytoluene (BHT).

An antioxidant widely used not only in cosmetics, but also in the food industry. It is quickly absorbed into the skin and stays in the tissues for a long time. Carcinogen.

Gamma Hexachloran - Lindane, hexachlorocyclohexane.

A pesticide used in agriculture. Trade names Kwell, linden, Bio-Well, GBH, G-well, Kildane, Kwildane, Scabene and Thionex. Added to creams, lotions and shampoos. Carcinogenic. Causes skin cancer. Very toxic to the nervous system. Damages the brain.

Hyaluronic acid, hyaluronate, hyaluronan - Hyaluronic acids.

This is the “latest squeak” in the cosmetics industry. It happens that cosmetic companies use only a small amount of this acid in their products, so long as the ingredient is mentioned in the composition on the sticker. It doesn't do the skin any good.

Glycerin (conditionally beneficial), 1,2,3-trihydroxypropane, 1,2,3-propanetriol - Glycerine.

Advertised as a beneficial moisturizer. It is a clear, syrupy liquid made by chemically combining water and fat. Water splits fat into smaller components - glycerol and fatty acids. This improves the penetration properties of creams and lotions and prevents them from losing moisture through evaporation. Glycerin is the basis of all fats. In general, fat is glycerin + fatty acids. Glycerin is prized in cosmetology for its moisturizing and water-retaining properties. Moisturizing effect - glycerin molecules are surrounded by water molecules (since glycerin has three hydrosilic groups) and, getting into the skin along with water, retains moisture.

But if you use a large percentage of glycerin - 40-50%, a harmful substance is formed by-side (this is what they talk about). Studies have shown that when the air humidity is below 65%, glycerin sucks water out of the skin to its full depth and holds it on the surface, instead of taking moisture from the air. Thus, it makes dry skin even drier.

Dimethylamine - Dimethylamine..

Carcinogen.

Dioxane, diethylenedioxide - 1,2-Dioxane –ethoxylated alcohols, 1,4 – dioxane, polysorbates, and laureths.

It is mainly found in shampoos. Contains nitrosamines, which are known to be carcinogens.

Cocamidopropyl Betaine - Cocamidopropyl Betaine.

Used in shampoos in combination with other surfactants (surfactants). Synthetic substance. Irritating to eyelids.

Collagen (not to be confused with vegetable liquid-soluble collagen), fibrillar protein - Collagen.

Collagen is a protein - the main part of the structural network of our skin. It is believed that with age, it begins to deteriorate, and the skin becomes thin and flabby. Some companies insist that collagen can improve the skin's own collagen structure. Others say that it is absorbed by the epidermis and moisturizes the skin.

Collagen is an insoluble fibrous protein whose molecule is too large to penetrate the skin. It is used in many cosmetic preparations. Obtained from animal skin or from milled chicken legs.

Collagen use is potentially harmful for the following reasons:

1. The large size of collagen molecules prevents its penetration into the skin. Instead of being beneficial, it settles on the surface of the skin, clogging up pores and preventing water from evaporating just like industrial oil. Forms a film on the skin, under which the skin can suffocate. It's like playing tennis with a soccer ball. (The molecular weight of any ingredient must be 3000 to penetrate the skin, 800 - into the cell and 75 - to get into the blood. The molecular weight of the components of most cosmetic products and shampoos is 10,000).

2. Collagen used in cosmetics is obtained by scraping off the skins of cattle or from the lower legs of birds. Even if it penetrates the skin, its molecular composition and biochemistry are different from that of a human, and it cannot be used by the skin.

Lanolin, wool wax, animal wax - Lanolin.

Advertisers found that the words “contains lanolin” (advertised as a beneficial moisturizer) helped market the product, and it was argued that “it has the ability to penetrate the skin like no other oil,” even though there is not enough scientific evidence for that. confirmations. Studies have found that lanolin causes sensitization of the skin, and even allergic rashes. There is a high content of pesticides, sometimes up to 50-60%. Very harmful to the skin: it clogs the pores, does not allow the skin to breathe. Possibly carcinogenic.

Ammonium laureth sulphate (ALS).

Easily penetrates the skin. Found in hair care products and bath foams. It is a poisonous, carcinogenic, mutagenic substance.

Sodium Laureth Sulfate - SLES.

Similar ingredient to SLS (ester chain added). Found in 90% shampoos and conditioners. It is very cheap and thickens with the addition of salt. Forms a lot of foam and gives the illusion that it is thick, concentrated and expensive. This is a fairly mild detergent. SLES reacts with other ingredients and forms dioxins in addition to nitrates. They corrode the hair follicle and slow down hair growth. It quickly enters the body and settles before our eyes, in the brain, and in the liver. It is excreted very slowly from the body. May cause blindness and cataracts. Carcinogenic. Irritating to skin and eyes, causing hair loss and dandruff. Causes serious allergic reactions. Very dry skin and scalp.

Used as a wetting agent in the textile industry.

Sodium lauryl sulfate, sodium dodecyl sulfate, sodium lauryl sulfonic acid - Sodium Lauryl Sulfate -SLS.

It is an inexpensive cleanser made from coconut oil, widely used in cosmetic cleaners, shampoos, bath and shower gels, bath foamers, and the like. It is perhaps the most dangerous ingredient in hair and skin care products.

In industry, SLS is used for cleaning garage floors, engine degreasers, car washes, etc. It is a very corrosive agent (although it does remove grease from the surface).

Sodium lauryl sulfate is used in clinics around the world as a skin irritation tester in the following way: researchers use this drug to irritate the skin in animals and humans, and then treat them with different drugs.

Recent research at the Georgia State University College of Medicine has shown that SLS penetrates the eyes, brain, heart, liver, etc. and lingers there. This is especially dangerous for children, in whose tissues it accumulates in high concentrations. These studies also show that SLS alters the protein composition of children's eyes and delays the normal development of these children, causing cataracts.

Sodium lauryl sulfate cleanses by oxidation, leaving an irritating film on body skin and hair. May promote hair loss and dandruff by acting on the hair follicles. Hair dries up, becomes brittle and splits at the ends.

Another problem. Sodium lauryl sulfate reacts with many ingredients in cosmetics to form nitrosamines (nitrates). These nitrates enter the bloodstream in a large number when using shampoos and gels, taking baths and using cleaners. If you wash your hair once with shampoo that contains SLS, it means saturating your body with a huge amount of nitrates, which are quickly carried by the blood throughout the body. It's like eating a kilo of ham stuffed with the same nitrates. Carcinogenic. Molecular weight SLS - 40 (substances with a molecular weight of 75 and less quickly penetrate into the blood).

Many firms often disguise their SLS products as natural, stating "sourced from coconuts."

Liposomes (not to be confused with phytoliposomes) - Liposomes (Nanosphenes or Micellization).

Considered a radical anti-aging agent. According to one of the latest theories, cell aging is accompanied by a thickening of the cell membrane. Liposomes are tiny sacs of fat and thymus hormone extract suspended in a gel. It is assumed that they, by merging with the cells, revitalize them and add moisture. However, recent scientific studies do not support these assumptions. The cell membranes of old and young cells are identical.
Thus, liposome humidifiers are another costly gimmick.

Lauramide Day - Lauramide DEA.

Lauric Acid is usually obtained from coconut or laurel oil and is used to foam and thicken various cosmetic preparations. It forms the basis for the production of soap, because it creates good foam... In addition, it is applied in detergents for washing dishes due to its ability to remove grease.
In a cosmetic formula, it reacts with other ingredients to produce nitrosamines, a known carcinogen. Dries hair, skin and scalp. Itching and allergic reactions.

Methylchloroisothiazolinone, commercial name Kathon CG, abbreviations: CMIT, CMI, MCI - preservative - Methyl Chloroisothiazolinine.

Para-Phenylenediamine Dyes..

Hair dyes: dark or brown colors... Carcinogenic when oxidized. Cause of various types of cancer - non-Hodgkin's lymphoma and multiple myeloma. Jacqueline Kennedy dyed her hair black every two weeks. Died of non-Hodgkin's lymphoma.

Petrolatum - Petrolatum.

Fat, a petrochemical product - petrolatum - has the same harmful properties as industrial oil. By retaining fluid, it prevents the release of toxins and wastes and interferes with oxygen penetration.

Polysorbates, oxyethylated sorbitans, nonionic surfactants - Polysorbate-n (20-85).

Used as an emulsifier. Causes skin irritation and contact dermatitis. Toxic.

Polyelectrolyte - Polyquaternium.

Abbreviation for polyethylene glycol, polyoxethylene, polygocol, polyether glycol. They cause allergic skin reactions and eczema. Contains dangerous levels of the highly toxic substance dioxane.

Propylene glycol, 1,2-propylene glycol - Propylene Glycol.

Polyethylene Glycol (PEG) - Butylene Glycol (BG) - Thylene Glycol (EG). Most used as a vehicle (after water) in a cosmetic formula. Propylene glycol is a petroleum derivative, sweet caustic liquid.

In skin care cosmetics and shampoos, it is claimed to be capable of retaining moisture in the skin. Actually draws moisture out of the skin. Degreases and dries out the skin. Irritating to eyes. It is cheaper than glycerin but causes more allergic reactions). It is believed to give the skin a youthful appearance. Its proponents are conducting research to prove that propylene glycol is a safe and effective ingredient. However, scientists believe it is harmful to the skin for the following reasons:

1. In industry, it is used as antifreeze in water cooling systems and as a brake fluid. It gives the skin a smooth and greasy feeling, but it does so by displacing components important to skin health.

2. While binding the liquid, propylene glycol displaces water at the same time. The skin cannot use it, it functions with water, not antifreeze.

3. The safety study data (MSDS) of propylene glycol shows that skin contact with propylene glycol can cause liver damage and kidney damage. In cosmetics, a typical composition includes 10-20% propylene glycol (note that propylene glycol is usually one of the first in the list of ingredients of preparations, which indicates its high concentration).

4. In January 1991, a clinical review was published by the American Academy of Dermatology regarding the association of dermatitis with propylene glycol. The report proved that propylene glycol causes a large number of reactions and is one of the main skin irritants even at low concentrations.

Research shows that this substance is mutagenic. It quickly penetrates the skin, destroys cellular proteins and is deposited in the body.

Stearomide propyl, EDTA tetrasodium salt - Stearamidopropyl Tetrasodium EDTA.

Forms nitrosamines in cosmetics. Nitrosamines are known carcinogens.

Styrene C8H8, phenylethylene, vinylbenzene - Styrene Monomer.

Carcinogenic, toxic, mutagenic. Irritating to skin and mucous membranes.

Talc - Talc

Obtained from magnesia silicate. It is believed that talcum powder is dangerous and toxic and should not be used in children as it can cause lung cancer. According to other sources, this applies only to talc mixtures containing lead.

Technical oil, Petroleum (mineral) oils - Mineral Oil (heavy and light).
This ingredient is derived from oil. It is a mixture of liquid hydrocarbons separated from gasoline. Used in industry for lubrication and as a dissolving liquid. When used in cosmetics as a moisturizer, the technical oil forms a water-repellent film and traps moisture in the skin. It is believed that by trapping moisture in the skin, you can make it softer, smoother and more youthful looking. The truth is that a film of technical oil retains not only water, but also toxins, carbon dioxide, waste and products of life, it prevents the penetration of oxygen. The skin is a living, breathing organ that needs oxygen. And when toxins accumulate in the skin and oxygen does not penetrate, the skin becomes unhealthy.

Studies have shown that the saturation of the skin with liquid trapped by the oil film slows down the growth and development of cells. The new skin cell migrates to the surface, where it is exfoliated and washed off. This process takes 20 days in young people and up to 70 days in older people. During this migration from the lower layers of the skin to the surface, the cell changes both structurally and in composition. These changes are necessary for the skin to remain healthy and act as a barrier and protector for the body.

When the skin is glued and the ducts overflow with a large amount of excess fluid saturated with toxins and wastes, the vital functions of the skin are disrupted. The cells stop developing normally and their growth slows down. Immature cells rise to the surface and cannot perform a barrier function. Such skin cracks and dries easily, becomes irritable and sensitive. Due to the slowdown in growth, the skin becomes weaker and thinner. Natural mechanisms of recovery and self-defense are weakened and harmful elements of the environment attack the skin faster and easier. In short, the skin shrinks quickly, becomes thinner and more sensitive, easily irritated. The youthful appearance of the skin and the glow fade as it loses its health. In fact, liquid is the only remedy for improving dry skin, but the wrong methods of moisturizing are very harmful and cause premature aging, not rejuvenation. Dr. T.G. Randolf, an allergist, discovered that this ingredient causes petrochemical allergies. Allergic reactions can be very serious, leading to arthritis, migraines, hyperkinesis, epilepsy, and diabetes. When taken orally, technical oil binds fat-soluble vitamins A, D, E and, preventing their absorption, removes them from the body. And, although only a very small amount is able to penetrate the skin, this trend is so dangerous that Adelle Davis in her "Let's eat right to stay healthy" says that she personally "is wary of using technical oil even in baby oils, cold creams and other cosmetic preparations "

Technical oil tends to dissolve natural sebum and increase dehydration. It is recognized as the most common cause of acne and various rashes in women using technical oil cosmetics. It was found that in the production of industrial oils, carcinogens are present in them, and in a strong concentration.

Tyrosine (alpha-amino-beta- (p-hydroxyphenyl) propionic acid) - Tyrosine.

Some tanning lotions contain tyrosine. Be sure that this will definitely be reflected in the advertising of a cosmetic product - an amino acid that enhances melanization (tanning) of the skin. But melanization is an internal process and smearing the lotion on the skin cannot affect it. Likewise, you can rub yourself with food to satisfy your hunger.

Manufacturers' claims of the effectiveness of tanning enhancers remain unconfirmed. Recent independent research has not supported these claims. It is doubtful that tyrosine can penetrate the skin to such a depth as to affect the melanization process.

Triclosan - Triclosan.

The latest advance in antibacterial chemistry. It is used in household cleaners and detergents, as well as in cosmetics.
Triclosan is a chlorophenol, a class of known carcinogenic chemicals. Irritating to skin. It is very toxic to the whole organism.
It has a negative effect on the liver, kidneys, lungs, brain, can cause paralysis, and reduces sexual functions.

Triethylamine - Triethanolamine (Trolamine, TEA).

Causes serious dermatitis on the skin of the face, makes it sensitive and allergic. Usually in cosmetics it regulates the pH balance. May contain nitrosamines which are highly carcinogenic.

Toluene, methylbenzene - Toluene (toluol).

Obtained from petroleum products. Reminiscent of benzen. Toxic. May cause anemia. Damages the liver. Irritating to skin and mucous membranes.

Humidifiers - Humectants.

Most moisturizers contain humectants. They are believed to attract moisture from the air. In fact, they draw moisture from the skin. Humectants including propylene glycol and glycerin act as humectants in humid environments. On the contrary, if you are in dry places, such as in the cockpit of an airplane or in a well-heated area, they draw moisture from the skin.

FDS - FDC-n (FD&C).

Available in various colors... Some are skin irritants, others are strong carcinogens. It is believed that there are still no levels of acceptable safe use for these products for each color category.

Phenoxyethanol - Phenoxyethanol..

Causes serious allergic reactions. Trade names - Arosol, Dowanol EPH, Phenyl Cellosolve, Phenoxethol, Phenoxetol and Phenonip.

Formalin DMDM, aqueous solution: 40% formaldehyde, 8% methyl alcohol and 52% water - Hydantoin DMDM..

May cause dermatitis. As a preservative, it can form formaldehyde, which is a dangerous carcinogen.

Phthalates, phthalic acid salts - Phthalates.

Dibutyl Phthalate - Diethyl Phthalate - Dimethyl Phthalate. Phthalates are widely used in cosmetics and perfumery. Interestingly, environmental laws regulate and control the use of phthalates as they are considered toxic.
In cosmetic products, there are not even warnings about their high toxicity.
They destroy the liver and kidneys, are very dangerous for the fetus, reduce the amount of sperm.

Fluoride, fluorine compound - Fluoride.

Dangerous chemical element. Especially dangerous in toothpaste. Scientists associate this element with the occurrence of dental deformities, arthritis, and allergic manifestations.

Fluorocarbons, perfluorocarbons - Fluorocarbons.

Usually used in hair sprays. Toxic to the respiratory tract.

Formaldehyde, methanal, formic aldehyde, formic acid aldehyde - Formaldehyde.

Used in nail polish, soaps, cosmetics and shampoos. Causes severe mucosal irritation. Trade name: DMDM ​​hydantoin or MDM hydantion.
Very toxic to the skin. Known carcinogen. Two substances from the formaldehyde family are used as preservatives in cosmetics: DMDM ​​(Dimethylol Dimethol Hydantoin) and Imidazolidinyl Urea. Toxic. Cause contact dermatitis.

Sodium cyanide, sodium cyanide, NaCN - sodium salt of hydrocyanic acid - Sodium Cyanide.

It is a poisonous, carcinogenic, mutagenic substance.

Placenta Extracts - Placental Extract - Placenta.

Placenta extract is dangerous in that, if all sanitary requirements were not followed upon receipt, it can cause very serious diseases. Is it worth risking your health ?!

Elastin (not to be confused with Cross-Linked Elastin) - Elastin.

Another ingredient touted as beneficial for skin and hair care. This substance is the structure that holds the skin cells in place. It is believed that as we age, elastin molecules break down and thus wrinkles form. In order to restore the skin, many cosmetic companies introduce elastin into their preparations.

Like collagen, elastin is obtained from cattle, and it also forms a suffocating film on the skin due to its high molecular weight. Elastin cannot penetrate the skin and, even when injected, does not perform its function due to the inappropriate molecular structure, because human elastin differs in structure from animal elastin.

Only one kind of cross-linked elastin is capable of penetrating and compatible with human skin. This form of elastin is called desmosin or isodesmosin.

Ethylene glycol, glycol, 1,2-dioxyethane, ethanediol-1,2 - Glycols.

They are used as humectants (substances designed to retain moisture in the skin). They can be of both animal and plant origin. They are also produced synthetically. Diethylene glycol and carbitol are toxic. Ethylene glycol causes bladder cancer. All glycols are toxic, carcinogenic and mutagenic.

Natural cosmetic

Natural cosmetics can be safely called, for example, the cream or mask that you made yourself from the natural products, plants, herbs you have.

As for the purchased industrial "natural cosmetics", it will only be more or less natural, which, in principle, is already quite good. But sometimes they can just lie.

There is no legal definition of the word "natural" that you see everywhere. The chemical definition of organic means that the compound simply contains carbon.

In cosmetics, the word "natural" can mean whatever the manufacturer wants. There are no legal obligations associated with this term. Often, "natural cosmetics" is just a publicity stunt.

There are no clear criteria for what a “natural” product can and cannot contain. Cosmetic preparations called "natural" can contain preservatives, dyes, and any other ingredients that cannot be called natural.

Thus, the products of the cosmetic industry the majority firms does not give the consumer what he expects. The benefits of such cosmetics, rather, psychological than the real one.
