There are three types of pimples, according to Kids Health. Blackheads, whiteheads and pustules form when oil and bacteria get stuck in the pores and hair follicles, causing an irritation underneath the skin. A pore that is clogged with dirt and oil and is open at the top is called a blackhead. You can reduce blackheads and other pimples at home, or with the help of a dermatologist.
Acne Cleanser
To help encourage skin exfoliation and remove dirt and oil from the skin, use an over-the-counter acne cleanser on problem areas twice a day. In the morning and before bed, wash the skin gently with the cleanser and warm water, then dry the area with a clean towel. Over-the-counter acne cleansers that contain benzoyl peroxide, resorcinol, salicylic acid, sulfur or lactic acid as an active ingredient are particularly effective in reducing acne.
Topical Prescription Medications
If your acne does not respond to over-the-counter acne cleansers, consult a dermatologist. A dermatologist may prescribe a topical prescription acne medication, like retinol, adapalene or tazarotene. Topical prescription medications contain a stronger dose of medication than over-the-counter cleansers, but may also cause side effects of redness and peeling of the skin. Consult your dermatologist if peeling does not go away within one month.
Oral Prescription Medications
If over-the-counter and topical prescription medications are not effective, your dermatologist may prescribe an oral medication. Oral antibiotics may help reduce bacteria on the skin to prevent acne from spreading. Isotretinoin, a strong prescription medication, may be used if acne does not respond to any other medications. Isotretinoin may cause severe side effects, including depression and thoughts of suicide. Take isotretinoin only while under the supervision of a doctor.
