What the gurus are saying

This exfoliant wins praise for combining gentle lactic acid with moisturizing action, making it effective without being harsh. The formula blends both AHA and BHA actives, and comes in a generous bottle size. Those with sensitive skin or anyone new to chemical exfoliants may find the gentler lactic acid approach easier to start with than stronger actives.

"This one from REN is also really great, it has lactic acid, which is also an AHA but more gentle, and it also moisturizes as it exfoliates."

"It comes in this big bottle and it has alpha hydroxy acids and beta hydroxy acids, so glycolic acid and salicylic acid. I like to shake it into my palms and I actually leave this in my shower. So I finish my shower, I blot myself off with my towel, and then I go in with this. This one does have a little bit of a tingle when you apply it to the skin, but it's still gentle enough that I feel comfortable applying it neck down."
