Patient Information. Conditions Treated A-Z. What is Acne? Definition Acne is a skin condition that causes pimples or "zits. Alternative Names Acne vulgaris; Cystic acne; Pimples; Zits Causes Acne occurs when tiny holes on the surface of the skin become clogged. Each pore opens to a follicle. A follicle contains a hair and an oil gland.
The oil released by the gland helps remove old skin cells and keeps your skin soft. The glands can become blocked with a mixture or oil and skin cells, the blockage is called a plug or comedone. If the top of the plug is white, it is called a whitehead. It is called a blackhead if the top of the plug is dark. If bacteria become trapped in the plug, the body's immune system may react to it, causing pimples.
Acne that is deep in your skin can cause hard, painful cysts. This is called nodulocystic acne. Some things that may trigger acne include: Hormonal changes that make the skin oilier. These may be related to puberty, menstrual periods, pregnancy, birth control pills, or stress. To help prevent the oil buildup that can contribute to acne, wash your face once or twice a day with a mild soap and warm water. Don't scrub your face hard with a washcloth — acne can't be scrubbed away, and scrubbing may actually make it worse by irritating the skin and pores.
Try cleansing your face as gently as you can. If you wear makeup or sunscreen, make sure it's labeled "noncomedogenic" or "nonacnegenic.
And when you're washing your face, be sure you take the time to remove all of your makeup so it doesn't clog your pores. Acne isn't really helped by the sun. Although a tan can temporarily make acne look less severe, it won't help it go away permanently — and some people find that the oils their skin produces after being in the sun make their pimples worse. If you use hair sprays or gels, try to keep them away from your face, as they also can clog pores.
If you have long hair that touches your face, be sure to wash it often enough to keep oil away. And if you have an after-school job that puts you in contact with oil — like in a fast-food restaurant or gas station, for example — be sure to wash your face well when you get home.
It also can help to wash your face after you've been exercising. Many over-the-counter lotions and creams containing salicylic acid or benzoyl peroxide are available to help prevent acne and clear it up at the same time.
You can experiment with these to see which helps. Be sure to follow the instructions exactly — don't use more than you're supposed to at one time your skin may get too dried out and feel and look worse and follow any label directions about allergy testing.
Some people do find that they notice their breakouts get more severe when they eat too much of a certain food. If you're one of them, it's worth trying to cut back on that food to see what happens. Sometimes even though they wash properly and try lotions and oil-free makeup, people get acne anyway — and this is totally normal.
In fact, some girls who normally have a handle on their acne may find that it comes out a few days before they get their period. Acne vulgaris and acne rosacea. In: Integrative Medicine.
