My dermatologists recommended me to use adapalene at night and benzoyl peroxide in the morning. I used this product (adapalene) for about a year. It worked in a few months . I didn't have breakouts for months but after a year my acne came back. My dermatologists said my skin might be resistant to the product so she recommended another product, but, I still recommended to use this product to others that have mild to moderate acne.
