Dr. Casale#LaRochePosayPartner Higher percentage BPO ‡ better. 10% benzoyl peroxide doesn't clear acne faster than 5%... Effaclar BPO is 5.5% micronized benzoyl peroxide, so the particles are small enough to get into the pore instead of sitting on the surface. Testing showed up to 63% less inflammatory acne in one week. #benzoylperoxide #acne #bpo @LaRochePosayUS #LaRochePosayUSA
