This 2.5% benzoyl peroxide is gel-based so it goes on clear and spreads easily. It is pharmaceutical grade, pH balanced, fragrance-free, and dye-free. It won"t "clump up" with moisturizers, and won"t turn white when you perspire. This treatment works best when used as part of The Regimen (acne.org/regimen). The Regimen is a step-by-step guide to clear skin.
