Glycolic acid, lactic acid, mandelic acid, and salicylic acid.

Only at night.

39-year-old board-certified dermatologist.

Not everything with the word acid is an exfoliating acid. I'm a 39 year old board certified dermatologist and let's break that down. What's an exfoliating acid? It's either an AHA or a bha. Things like glycolic acid or lactic acid or mandelic acid or salicylic acid. Those are the big ones on the market. Strongly recommend to you that you use them only at night, maximum three to four times a week so that your skin barrier does not get wrecked in the process and you don't look like a pizza.
