Benzoyl Peroxide
What is Benzoyl Peroxide?
Benzoyl peroxide is an organic peroxide compound, typically a white crystalline powder, derived from benzoyl acid. In skincare, it belongs to the anti-acne active category, commonly found in gels, creams, lotions, spot treatments, and facial washes. It works by decomposing on the skin to release oxygen, which destroys acne-related bacteria such as Cutibacterium acnes thriving in oily environments. This oxidative action also breaks down excess sebum and dead skin cells, promoting clearer pores through mild exfoliation. As an oxidizing agent, it supports its role in blemish control products, both rinse-off cleansers and leave-on applications, with formulations stabilized for safety and efficacy in targeting oily, congestion-prone skin.
