Salicylic Acid
Strong evidence for acne- It usually helped clear acne, though results were sometimes mixed and a few studies only showed it matched other treatments
- 30 studies back this, including large reviews
- It often worked about as well as tretinoin, adapalene, benzoyl peroxide, mandelic acid, Jessner's solution, and some light treatments
- Some studies found it worked better when used with other treatments than when those treatments were used alone
- Side effects were usually milder than with some comparison treatments, with less dryness and fewer side effects overall
