If having a glowing, youthful complexion with improved fine lines, reduced discoloration, and a smoother texture is way up there on your priority list, you've come to the right place. 

In case you didn't

know already, there's a magical skincare ingredient out there that can do all that and then some. Seem too good to be true? According to dermatologists, it's not. This otherworldly ingredient, otherwise known as glycolic acid, is a chemical exfoliant AHA (alpha-hydroxy acid) that works almost as well as getting a professional facial. "It's a substance derived from sugar cane and is known for its exfoliating benefits," explains Marisa Garshick, a board-certified dermatologist. "It helps to get rid of dead skin cells and therefore brightens the skin."
