What skin issue can benzoyl peroxide effectively address?

Benzoyl peroxide is widely recognized for its effectiveness in treating bacterial acne. This is primarily due to its antibacterial properties, which help to eliminate the bacteria that contribute to the development of acne. It works by penetrating the skin and releasing oxygen, which targets the anaerobic bacteria responsible for acne formation, reducing inflammation and promoting the healing of existing blemishes.

In the context of the other options, chronic dryness, dehydration lines, and sun damage are not addressed by benzoyl peroxide. Chronic dryness and dehydration lines often require moisturization and hydrating ingredients, while sun damage typically necessitates protective measures like sunscreen and products that may contain antioxidants or retinoids to assist in repair. Therefore, the specific action of benzoyl peroxide in combating bacterial acne distinguishes it as the appropriate choice for this skin issue.
