A lightweight, foaming acne cleanser with 2% salicylic acid helps unclog pores and wash away dead skin and impurities. Cooling menthol leaves skin feeling refreshed. 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.
