A lightweight, foaming acne cleanser with 2% salicylic acid. This effective cleanser helps unclog pores and washes away dead skin cells, leaving skin feeling clean and refreshed. Includes calming menthol to help cool irritated skin. To effectively treat acne-prone skin, Obagi recommends using both salicylic acid and benzoyl peroxide as part of a complete and balanced acne treatment regimen. This has shown to be highly effective, with benzoyl peroxide actively targeting bacteria, while salicylic acid gently exfoliates.
