How Does Benzoyl Peroxide Work?

Benzoyl peroxide works by peeling away the buildup of old skin cells and sebum that collect in the pores and cause acne. When applied to affected skin areas, benzoyl peroxide releases oxygen that is able to reach deep inside the clogged pore to break down the skin and sebum plug. It is very effective as both an antibacterial and antiseptic agent that quickly and easily kills acne-causing bacteria.
