Alpha-hydroxy acids (AHAs)
Skin care products containing alpha-hydroxy acids (glycolic, lactic, tartaric, and citric acids) have become increasingly popular in recent years. Lotions and Creams that contain alpha-hydroxy acids may help decrease fine lines, shrink enlarged pores, help correct pigmentation problems like age spots. Some side effects have been seen and include mild irritation and sun sensitivity. To avoid burning, sunscreen should be applied in the morning. Always start with a product that contains a maximum concentration of 10-15% AHA to help avoid skin irritation. You should only apply the skin care product every other day, gradually working up to daily application which will allow your skin to get used to alpha-hydroxy acids.
