Acne is a common skin condition that affects most people at some point. It causes spots to develop on the skin, usually on the face, back and chest.
The spots can range from surface blackheads and whiteheads – which are often mild – to deep, inflamed, pus-filled pustules and cysts, which can be severe and long-lasting and lead to scarring.
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.
Signs and symptoms
Acne signs and symptoms vary depending on the severity of your condition
- Whiteheads (closed plugged pores)
- Blackheads (open plugged pores — the oil turns brown when it is exposed to air)
- 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)
Acne is caused when tiny holes in the skin, known as hair follicles, become blocked.
Treatment for acne depends on how severe it is. It can take several months of treatment before acne symptoms improve.
If you just have a few blackheads, whiteheads and spots, you should be able to treat them successfully with over-the-counter gels or creams (topical treatments) that contain benzoyl peroxide.
Some self-help techniques may also be useful:
- Do not wash affected areas of skin more than twice a day. Frequent washing can irritate the skin and make symptoms worse.
- Wash the affected area with a mild soap or cleanser and lukewarm water. Very hot or cold water can make acne worse.
- Don't try to "clean out" blackheads or squeeze spots. This can make them worse and cause permanent scarring.
- Avoid using too much make-up and cosmetics. Use water-based products that are described as non-comedogenic (this means the product is less likely to block the pores in your skin).
- Completely remove make-up before going to bed.
- If dry skin is a problem, use a fragrance-free, water-based emollient.
- Regular exercise cannot improve your acne, but it can boost your mood and improve your self-esteem. Shower as soon as possible once you finish exercising as sweat can irritate your acne.
- Wash your hair regularly and try to avoid letting your hair fall across your face.
