Which product is typically used to treat acne?

Benzoyl peroxide is a widely recognized ingredient specifically formulated to treat acne. It works through multiple mechanisms; primarily, it kills the bacteria known to cause acne—Cutibacterium acnes—on the skin. Additionally, this compound helps to reduce inflammation and unclog pores by promoting the turnover of skin cells, which can help prevent the formation of new acne lesions.

In contrast, while hyaluronic acid is beneficial for hydrating the skin and maintaining moisture, it does not directly target the causes of acne. Glycolic acid, an alpha-hydroxy acid, is primarily used for exfoliation and improving skin texture and tone, which can indirectly assist with acne but is not a primary treatment. Vitamin E is known for its antioxidant properties and skin healing benefits but lacks specific action against acne. Thus, benzoyl peroxide stands out as the most effective and commonly recommended treatment for acne among the options provided.
