CLAIM This three-step pack controls breakouts with a salicylic acid cleanser and treatment, and a lotion with niacinamide to help fade spots. EXPERT OPINION Salicylic acid unclogs pores and has anti-inflammatory effects, says Dr. Noëlle Sherber. The system doesn't contain benzoyl peroxide, which she says can irritate skin. OUR VERDICT This kit cleared up our skin within a week! In less than a month, even our scars on the chin looked lighter and less noticeable.
