What topical ingredient is widely known for treating acne?

Benzoyl peroxide is a powerful topical ingredient that is widely recognized for its effectiveness in treating acne. It functions by penetrating the pores and releasing oxygen, which specifically helps to eliminate acne-causing bacteria, particularly Propionibacterium acnes. This mechanism not only contributes to reducing the number of breakouts but also helps to prevent the formation of new acne lesions. Additionally, benzoyl peroxide has anti-inflammatory properties that can reduce redness and swelling associated with active breakouts.

While other ingredients such as salicylic acid, glycolic acid, and retinol also play significant roles in acne treatment, benzoyl peroxide is particularly noted for its ability to tackle stubborn acne and is often used in combination with other treatments for enhanced effectiveness. Its ability to dry out excess oil and exfoliate dead skin cells further solidifies its reputation in acne management regimens.
