Clearasil is a skin-care brand that treats and prevents acne. Invented in 1950, Clearasil was the first dermatological brand targeted toward teenagers to treat pimples and blackheads. Nowadays, Clearasil offers a wide variety of cleansers, cleansing pads, creams and gels for both teens and adults. Many Clearasil products contain acne-fighting ingredients such as benzoyl peroxide or salicylic acid.

Purchase Clearasil products designed for your skin type. Clearasil offers more than 20 products that target specific kinds of skin, including the oily or blackhead-prone. If you exercise frequently, you may want to try Clearasil's Deep Cleanse line. Use a cleanser for the entire face, and a cream or gel for on-the-spot treatment. To treat regular breakouts, try cleansing pads. These products should be available at your local drugstore or at sites such as Drugstore.com.

Wash your face nightly with a cleanser to remove pore-clogging dirt and oil. Massage the cleanser onto your face for 20 to 30 seconds. Then rinse with splashes of warm water.

Use a cleansing pad if you develop pimples and blackheads frequently. These pads remove any traces of the dirt and oil that clog pores and cause acne. Wipe one pad over your face and neck, up to three times per day. Do not wet the pads with water, and do not re-use them. If your skin becomes dry, cut back to only one pad per day.

Apply Clearasil cream or gel to problem areas where you have a pimple or might be getting one. Squeeze a small dollop of cream or gel onto your finger. You can also use a cotton swab to pinpoint trouble spots without drying the surrounding skin.
