According to the "Physicians Desk Reference," it is important to use sunscreen when using benzoyl peroxide, an active ingredient in many over-the-counter acne medicines. Kidshealth.org underscores the importance of this and adds that benzoyl peroxide can be drying to the skin. People with acne are sometimes hesitant to apply lotions and other products to their skin, fearing that they may exacerbate breakouts. However, keeping your skin hydrated and protected from the sun can often help when non-irritating, non-comodogenic products are used.
Wash hands with warm water and soap for 20 seconds. It is important to always have clean hands when caring for acne-prone skin, as surface bacteria can make acne worse. Dry hands well with clean towel.
Deposit whatever normal amount of benzoyl peroxide lotion you normally use into the palm of one hand. Add a dime-size amount of Cetaphil moisturizer with sunscreen and blend lightly with a cotton swab.
Apply the lotion mixture to your face and neck gently, in a light, circular motion with your fingertips. Avoid the areas surrounding your lips and eyes, which should not come into contact with with benzoyl peroxide. Blend the lotion mixture into skin until it is just absorbed, being careful to not rub the skin too hard or for too long.
