Glycolic Acid

Function: Exfoliant and humectant
Origin: Natural

Glycolic acid is a type of alpha hydroxy acid (AHA) that, like the other ingredients in this category, moisturizes and exfoliates the skin.

With its exfoliating power, glycolic acid helps slough off dead skin cells, which can lead to the improvement of several signs of aging, including sun damage, uneven skin tone, patches of rough and scaly skin, fine lines and wrinkles. Studies also show that glycolic acid dramatically increases skin hydration, including increasing the skin's natural hyaluronic acid content.
