Overview: Topical adapalene/benzoyl peroxide is a gel that is applied to the skin to treat acne. It contains two medicines that work in different ways to help manage acne. Common side effects include dry skin, stinging, redness, or irritation where the medicine is applied. This medicine can make you sensitive to sunlight.

Uses

What is topical adapalene/benzoyl peroxide used for?

Topical adapalene/benzoyl peroxide is commonly used to treat acne vulgaris. Acne vulgaris is a common type of acne that causes blackheads, whiteheads, and other types of pimples on your skin. It often appears on the face, chest, shoulders, and back.

Topical adapalene/benzoyl peroxide may also be used for other conditions as determined by your health care provider.

How does topical adapalene/benzoyl peroxide work (mechanism of action)?

This medicine, which is applied to the affected skin, has two ingredients: adapalene and benzoyl peroxide. Adapalene helps control skin cell growth and reduce inflammation (swelling) to prevent acne. Benzoyl peroxide kills bacteria (germs) and helps remove dead skin cells to keep your pores clear.
