Benzoyl Peroxide is a common topical treatment used primarily for acne. It works by killing bacteria on the skin, reducing inflammation, and helping to unclog pores. This ingredient is often found in various over-the-counter creams, gels, and cleansers. When applied, Benzoyl Peroxide can cause dryness or irritation, so it's important to start with a lower concentration and gradually increase usage. It is effective for mild to moderate acne and is sometimes combined with other treatments for better results. Always consult a healthcare professional before starting any new skincare regimen.
