What are alpha-hydroxy acids (AHAs) and how are they used in skin care products?

ANSWER

When you shop for makeup and skin care products, you may see other ingredients on their labels:

Alpha-hydroxy Acids (AHAs)

This group includes glycolic, lactic, citric, and tartaric acids. They're in many products.

They exfoliate the skin, reducing fine lines, age spots, acne scars, and uneven skin color. You can get peels with high concentrations of AHAs from a beauty specialist (esthetician) or dermatologist, but you can use lower concentrations -- between 5% and 10% -- in creams or lotions on a daily basis.
