Acné
Acné
Acné is a common skin condition that occurs when hair follicles under the skin become clogged. This often results in whiteheads, blackheads, or pimples, and usually appears on the face, forehead, chest, upper back, and shoulders. Acné is most common among teenagers, though it affects people of all ages.
Causes
There are four main factors that cause acné:
- Excess oil production
- Hair follicles clogged by oil and dead skin cells
- Bacteria
- Excess activity of a type of hormone (androgens)
Symptoms
Acné signs and symptoms vary depending on the severity of your condition:
- Whiteheads (closed plugged pores)
- Blackheads (open plugged pores)
- Small red, tender bumps (papules)
- Pimples (pustules), which are papules with pus at their tips
- Large, solid, painful lumps beneath the surface of the skin (nodules)
- Painful, pus-filled lumps beneath the surface of the skin (cystic lesions)
Treatment
Acné treatments aim to reduce oil production, speed up skin cell turnover, fight bacterial infection, or reduce inflammation. This helps to prevent scarring and prevent new acné from forming.
Prevention
While it's not always possible to prevent acné, there are steps you can take to help reduce its severity and prevent new breakouts:
- Wash your face twice a day and after sweating
- Use your fingertips to apply a gentle, non-abrasive cleanser
- Avoid certain products, such as facial scrubs, astringents, and masks
- Try not to scrub or pick at your pimples
- Keep your hair clean and off your face
- Avoid touching your face or leaning your face on objects
