Clear acne and unclog pores with PanOxyl Clarifying Exfoliant 2% Salicylic Acid. Skin can become dry and lackluster when dead skin cells build up on the surface. Salicylic Acid, a Beta Hydroxy Acid (BHA), helps to dissolve dead skin and minimize the production of certain skin oils. Regular exfoliation removes the oil buildup, leading to a smoother, clearer and breakout-free complexion. This gentle leave-on exfoliating treatment contains the highest concentration of Salicylic Acid available over the counter.
