These Lactic Acid Lotions Are Perfect for Gentle Exfoliation

Exfoliation is a key component to glowing skin, and there are two main ways you can do it: via chemical exfoliation, like alpha hydroxy acids (AHAs), or physical exfoliation, like a scrub. Lactic acid falls under the first exfoliation umbrella and is kind of the unsung hero of the chemical exfoliation world though you probably think of salicylic or glycolic acid first.

However, lactic acid is a glow-inducing superstar in its own right because it manages to both exfoliate and hydrate skin making it unique among the chemical exfoliant heavy hitters. We tapped Joshua Zeichner, MD, Mount Sinai Hospital director of cosmetic and clinical research, to give us all the details on lactic acid lotions and what they can do for our skin.
