What the science says
Glycolic acid has strong evidence for signs of aging, as most studies found it improved fine lines, rough texture and dark spots in sun-damaged skin 1. Salicylic acid has some evidence for acne, reducing pimples, blackheads and whiteheads, and often working about as well as other common acne treatments 2. Glycolic acid also has some evidence for acne, with most studies reporting fewer blackheads and whiteheads, though stinging and peeling were the most common side effects 3.
