Acne is characterised by lesions that appear on the face, neck, back, chest, and arms of an individual. They may be blackheads (comedones), whiteheads (pustules), Inflammation (acne vulgaris), and, in the more severe forms, cysts and scarring (acne conglobata).
Acne results from the Inflammation of blocked pores. Although most often present during puberty, due to over-secretion of oil by the sebaceous glands, acne can also occur in adulthood. Some speculate it is caused, at least in part, by genetic factors. One type of adult acne, rosacea, occurs most often in middle-aged people with fair Skin, and can be the result of alcohol abuse or a depressed Immune System.
In mild cases, frequent washing (but no more than three times a day) of the face and affected areas might clear up the condition. More severe cases of acne can require the attention of a dermatologist.
