Also known as glycolic acid and hydroxyacetic acid, is an extract of sugar cane, sugar beet or grape. However, 99% of AHAs used in cosmetics come from laboratory synthesis.
In weak concentration (4% and less), AHAs increase moisture in the outer layers of the skin. In higher concentration -- above 4% -- and with an appropriate acidity level (pH 3-4), AHAs may have an exfoliating effect that reduces wrinkles and uncovers a younger, fresher looking skin. The most effective and scientifically proven AHAs are glycolic acid and lactic acid. AHAs may irritate skin. It is recommended to gradually increase tolerance to AHAs contained in products.
