Benzoyl peroxide is a common ingredient in skincare known for its effectiveness in treating acne. It works by killing the bacteria that contribute to acne, reducing inflammation, and helping to unclog pores. Available in various concentrations, benzoyl peroxide can be found in cleansers, creams, and spot treatments. It is often used to address both inflammatory and non-inflammatory acne lesions. While it can be highly effective, it may cause dryness or irritation, so it's advisable to start with lower concentrations and gradually increase as tolerated. It's important to use sunscreen when using benzoyl peroxide, as it can make the skin more sensitive to sunlight. Overall, benzoyl peroxide is a widely used and well-established solution for managing acne breakouts.
