Pimples are often associated with puberty, when hormone levels are changing, but even adults can develop acne. KidsHealth.org describes a pimple as a skin pore that becomes clogged with sebum, a naturally occurring oil that lubricates the skin and hair. Redness and protruding white-headed bumps are common signs of a pimple. When the pimple becomes infected or begins to heal, it can itch. Proper skin care can alleviate the itch and prevent infection. When itching is intense, persistent or is accompanied by pus, a skin infection is likely to blame. A skin infection should be treated by a health care professional.
Wash the skin with a mild, non-drying soap once or twice per day. The University of Maryland Medical Center suggests removing all dirt or makeup and washing after exercise.
Rinse the skin with warm water. For itchy patches of pimples, wet a wash cloth with warm-to-hot water and place it over the area for five to ten minutes. This can soften the skin and encourage pus to leak from the pimple. Rinse the skin again with warm water before patting dry with a fresh towel.
Apply a small amount of over-the-counter acne treatment to the pimples. The University of Maryland Medical Center recommends products containing benzoyl peroxide, sulfur, resorcinol or salicylic acid. These products can kill bacteria and help dry the pimple.
Apply a thin layer of oil-free moisturizer to the skin. When possible, use a product that has sunscreen to protect the skin affected by acne from further damage.
Contact a health care professional if daily cleansing and acne treatment do not improve itching. This can be a sign of a skin infection that requires oral or topical prescription-strength antibiotics.
