Acne vulgaris, commonly known as pimples or blemishes, is an unsightly skin condition which greatly affects self-esteem. Ance is characterized by the presence of open and closed comedones (blackheads and whiteheads, respectively). More severe acne includes erythema (reddening) and nodules (bigger collections of inflammation and, sometimes, pus under the skin). In normal skin, hair grows out of pores called follicles. The human body produces sebum (an oily substance) from glands at the bottom of the follicles which helps lubricate the hairs. Acne is caused by blockages of the hair follicles with oil and skin cells. There is also some involvement of a bacteria in the follicles called Propionibacterium acnes. Acne can occur all over the body but is most common in the areas of the body with the highest amounts of sebaceous glands: the face, back and upper chest. Acne typically worsens near puberty due to increases in androgens (a type of hormone) and affects most teenagers. For most people, the amount of acne will decrease with age. However, acne is a problem that can persist throughout life. Though no genetic link is known, acne seems to run in families. Acne is worsened by stress, poor hygiene, and hormonal changes such as those that happen with menstrual cycles in women or anabolic steroid use. Though people commonly believe that fatty foods and chocolate make acne worse, no evidence exists that dietary choices have an effect on the severity of acne. Acne can have effects on both physical appearance and self-esteem. Acne can have long-term effects on a person’s appearance, including scarring and hyperpigmentation (darkened discoloration of the skin).
