We’ll admit the title ‘acid’ is a bit confusing; most acids conjure up notions of exfoliating peels, which does not closely resemble hyaluronic acid’s benefits at all. Name aside, remember that exfoliating acids like AHAs and BHAs do not occur naturally in the body and are sourced from things like citrus fruits and milk. These types of ingredients are generally used to exfoliate, treat hyperpigmentation, and calm acne. And some of these acids (like the lactic acid found in The Shortcut) are humectants too.
