Acne
A skin condition characterized by whiteheads, blackheads and inflamed red pimples. Acne occurs when pores become clogged with too much oil and begin to collect dirt, debris and bacteria. Acne commonly appears on the face and shoulders but may also occur on the trunk, arms, legs and buttocks. Outbreaks are usually triggered by hormonal changes related to menstrual periods, pregnancy, birth control pills or stress; greasy or oily cosmetic and hair products; certain drugs; and high levels of humidity and sweating. A doctor or dermatologist should be contacted if self-care measures and over-the-counter medicines do not help after several months; the acne is severe or getting worse; or if scars develop after the acne has cleared up.
