# Benzoyl Peroxide

## Quick Summary

Benzoyl Peroxide is an OTC acne-care ingredient used in cleansers and leave-on products for inflamed-looking pimples and breakout-prone skin. Common OTC strengths include 2.5%, 5%, and 10%. It can be useful, but it may dry or irritate skin and can bleach colored fabrics or hair.

## What It Is

Benzoyl Peroxide is a common acne-care active found in rinse-off cleansers and leave-on products. It is often used when the breakout pattern includes inflamed-looking pimples rather than only blackheads or rough texture.

## Mechanism

Benzoyl Peroxide is used for acne-prone routines because it acts against acne-associated bacteria and helps reduce the look of inflamed breakouts over time. In consumer terms, it belongs in the lane of breakout control, not general brightening or hydration.
