acne
a disorder of the skin, the commonest of which is acne vulgaris in adolescents, characterized by the presence of pustules and blackheads. SEBACEOUS GLANDS in the skin become overactive (becouse of hormonal influence) and there is a greater production of SEBUM and proliferation of bacteria, which cause infection. The hair follicles become blocked and pustules from, which eventually turn black. The condition usually resolves with time but can be eased with creams and sometimes antibiotics. Other forms of acne also occur, see ROSACEA .
Acne is a common skin disease that causes pimples. Pimples form when hair follicles under your skin clog up. Most pimples form on the face, neck, back, chest, and shoulders. Anyone can get acne, but it is common in teenagers and young adults. It is not serious, but it can cause scars.
No one knows exactly what causes acne. Hormone changes, such as those during the teenage years and pregnancy, probably play a role. There are many myths about what causes acne. Chocolate and greasy foods are often blamed, but there is little evidence that foods have much effect on acne in most people. Another common myth is that dirty skin causes acne; however, blackheads and pimples are not caused by dirt. Stress doesn't cause acne, but stress can make it worse.
If you have acne:
- Clean your skin gently
- Try not to touch your skin
- Avoid the sun
Treatments for acne include medicines and creams.
