Acids in cosmetics: why are they needed and which one to prefer

GLYCOLIC ACID

Theory

One of the types of fruit acids that are extracted both synthetically and from natural plant components – there is no significant difference between them. Glycolic acid has a fast and deep action, which is not typical for most AHAs: it penetrates the superficial layers of the facial skin due to its small molecular size.

“Glycolic acid in various concentrations in cosmetics can serve several purposes. For a light antiseptic effect, a concentration of up to 5% is enough, but if you need to lighten the skin tone and narrow the pores, then you should pay attention to a higher concentration – − 10%, – says Alesya Shishova, cosmetologist-aesthetician, member of the International Organization of Naturopaths, cosmetologist of the Art&amp brand ;Fact. – When fighting age-related skin changes, smoothing wrinkles, a concentration of 15-20% may be required. At the same time, in home care products, the PH content in the composition should not be extremely acidic – at the level of 3-4.5 in order to avoid a difficult rehabilitation period.

Glycolic acid is contained in three novelties of the Russian brand Art&Fact. Peeling foam, which is designed for oily, combination and problematic skin prone to rashes, gently but effectively cleanses the skin, preparing it for chemical peeling. Immediately after the foam should be applied tonic-exfoliant, which regulates the sebaceous glands, exfoliates dead skin cells and fights inflammation. And finally, the third stage of skin care – facial peeling serumwith 15% glycolic acid, 3% gluconolactone, 3% lactic acid and 2% salicylic acid. This homemade superficial chemical peel is an excellent prophylaxis for deep cleansing of skin with stage 1 or 2 acne (open/closed comedones, papules). The procedure evens out the texture and relief of the skin during recovery and recovery after treatment, lightening congestive spots and post-acne marks.

MANDEAL ACID

Theory

Mandelic acid is considered one of the most delicate. Due to its special molecular structure, it penetrates the skin more slowly, so cosmetologists recommend products with mandelic acid when caring for problematic, sensitive or oily skin.

This acid is obtained from bitter almonds, hence, in fact, the name. It has powerful antibacterial properties, exfoliating effect and the ability to activate metabolic processes in cells. This acid can be present in peels, serums, gels, lotions, masks and topical products and performs a cleansing, renewing and exfoliating function.

LActic Acid

Theory

< pstyle="text-align:start">Lactic acid is obtained by lactic acid fermentation of sugars, it is present naturally in our body. For example, when you work hard at the fitness club, and the next day all your muscles hurt, this is precisely the result of the production of lactic acid. Lactic acid is also found in our skin, and its reduction leads to dryness and flaking. Therefore, it can be used to moisturize, even out skin tone and texture.

SALICYLIC ACID

Theory

Salicylic acid is considered almost the main “fighter” against skin imperfections. That is why almost all acne, blackhead and oily products contain this ingredient. It was first obtained at the end of the 19th century, from willow bark, and since then they have been actively used as part of cosmetics. The only limitation in the use of salicylic acid is individual intolerance. And, of course, owners of sensitive and dry skin should also stay away from it.

Garnier Blackhead Cleansing Gel, in addition to its own salicylic acid, it also contains a cleansing zinc, known for its ability to regulate the production of sebum. As a result, the formula has a double effect: on the one hand, it deeply cleanses the pores and gives the skin a healthy look, on the other hand, it frees the pores from excess fatty secretions, eliminates oily sheen and narrows the pores. But before you deal with black dots, still find out in advance whether the increase in oily skin is caused by some serious reasons – for example, a violation of the functions of the endocrine system or intestines. Of course, if the cause is established, it is necessary, first of all, to try to eliminate it, that is, to cure the disease that
adversely affects the skin. If there are no such problems, then with the help of proper care and cosmetic preparations for oily skin, its appearance can be significantly improved.

AHA-ACIDS< /strong>

Theory
