The AHA from My Cosmetik also known as fruit acids are powerful exfoliating agents from the family of "enzymatic exfoliators". They stimulate cell renewal and skin microcirculation. They improve the appearance of the skin and make it more elastic. They even out the complexion, purify the skin, reduce wrinkles, spots and skin imperfections. AHAs are typically used for their potent exfoliating and antioxidant properties (depending on dosage). The exfoliating action is explained by the presence of fruit acids, which allows a skin peel without grain or mechanical action. This peel helps both tighten the skin pores and effectively remove impurities and dead skin. The skin then breathes better and regenerates itself more quickly. AHAs are also powerful antioxidants capable of fighting against free radicals, responsible for premature aging of the skin. The origin of the formation of free radicals can be very varied: pollution, tobacco, sun rays, stress, certain medications, etc. AHAs are high-end ingredients in your home cosmetics, to protect and beautify your skin. AHAs or alpha-hydroxy acids are acids obtained from fruits (lemons, blackberries, apples and grapes). They are mainly citric, lactic, malic, tartaric and glycolic acids. These active ingredients have exceptional antioxidant and exfoliating properties.
