Acne is a common skin disease that causes pimples, which form when hair follicles under the skin clog. Most appear on the face, neck, back, chest and shoulders.
- Who: anyone, but it's common in teenagers and young adults.
- Serious? No — but it can leave scars.
Causes
No one knows exactly. Hormone changes, such as during the teen years and pregnancy, probably play a role.
Myths
- Chocolate and greasy foods: often blamed, but there is little evidence that foods affect acne much for most people.
- Dirty skin: blackheads and pimples are not caused by dirt.
- Stress: doesn't cause acne, but can make it worse.
If you have acne
- Clean your skin gently.
- Try not to touch your skin.
- Avoid the sun.
Treatments include medicines and creams.
