Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all males and females during puberty; the only exception being teenage members of a few primitive isolated tribes living in Neolithic societies. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.Acne appears on the skin as...
- congested pores ("comedones"), also known as blackheads or whiteheads,
- tender red bumps also known as pimples or zits,
- pustules, and occasionally as
- cysts (deep pimples, boils).
You can do a lot to treat your acne using products available at a drugstore or cosmetic counter that do not require a prescription. However, for tougher cases of acne, you should consult a physician for treatment options.
