What is acne? What are the different types of acne?

Acne (acne vulgaris, common acne) is not just a problem for teenagers; it can affect people from ages 10 through 40. It is not unusual for women, in particular, to develop acne in their mid- to late-20s, even if they have not had breakouts in years (or ever). On the positive side, those few individuals who have acne into their 40s may well grow out of it. Acne can appear on the skin as any of the following:

1. congested pores ("comedones"),
2. whiteheads,
3. blackheads,
4. pimples ("zits"),
5. pustules, or
6. cysts (deep pimples, boils). The pus in pustules and cysts is sterile and does not actually contain infectious bacteria.

These blemishes occur wherever there are many oil (sebaceous) glands, mainly on the face, chest, and back.

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.
