Acne is a common skin condition that causes pimples. These bumps usually arise on your face. Acne can also appear on your back, chest, or shoulders.
Anyone can get acne. But it is most common in teens and young adults. For most people, acne goes away by about age 30.
Acne usually pops up when hair follicles under the skin become clogged with oil or other substances. This can lead to swelling and redness, or inflammation.
There are different types of acne, including whiteheads, which produce a white bump. Blackheads look black because air changes the color of oils in the clog.
The color is not caused by dirt. Severe nodular acne, sometimes called cystic acne, can cause deep, painful, pus-filled bumps.
Acne can usually be treated with over-the-counter products that you put on the skin. For more severe acne, health care providers may suggest prescription treatments.
Stress or certain foods do not cause acne, but they may make it worse. Pressure from sports helmets, tight clothes, or backpacks can also inflame acne.
If you have acne, take good care of your skin. Wash gently and avoid strong soaps or rough scrub pads. Resist the temptation to squeeze or pick at pimples. That can lead to scars or dark blotches. Choose oil-free cosmetics and hair care products.
