Secrets of youth: acids for your skin

Modern women are increasingly thinking about the composition of cosmetics and its effect on the skin. It is important to choose the right means to avoid unpleasant consequences. Alpha-hydroxy acids (AHA) for skin rejuvenation deserve special attention. Let’s find out what these substances are and how they work.

Alpha Hydroxic Acids: Ancient Rejuvenation Secrets

Alpha Hydroxic Acids (AHA) have been used for skin care since Cleopatra’s time in dairy baths. Today they are part of many moisturizers, tonics and lotions. AHA is obtained from sugars contained in milk and fruits. The most famous are glycolic and lactic acids that penetrate deeply into the skin. Also popular are apple, citric and acetic acid.

How alpha hydroxy acids work

Alpha hydroxy acids act as exfoliating agents, contributing to the renewal of skin cells. They stimulate collagen and elastin production, reduce wrinkles, make skin smooth and soft, and lighten pigment spots. To achieve the effect it is necessary to use cosmetics with AHA daily for several months. The optimal concentration of AHA is 5% to 8% and pH 3 to 4.

Side effects and precautions

AHA has two main side effects: skin irritation and increased sensitivity to the sun. Irritation can manifest red, burning, itching and pain, and in case of severe irritation on the skin may remain scars. AHA also increases skin’s sensitivity to ultraviolet light, which can increase photoaging. Therefore, when using cosmetics with AHA it is necessary to use sunscreen with SPF not less than 15.
