Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. It causes whiteheads, blackheads or pimples. Acnes is most common among teenagers, though it affects people of all ages.
Effective acne treatments are available, but acne can be persistent. The pimples and bumps heal slowly, and when one begins to go away, others seem to crop up.
Depending on its severity, acne can cause emotional distress and scar the skin. The earlier you start treatment, the lower your risk of such problems.
Acne signs 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 under the skin (nodules)
- Painful, pus-filled lumps under the skin (cystic lesions)
it is usually appears on the face, forehead, chest, upper back and
Risk factors for acne include:
Age. People of all ages can get acne, but it’s most common in teenagers.
Hormonal changes. Such changes are common during puberty or pregnancy.
Family history. Genetics plays a role in acne. If both of your parents had acne, you’re likely to develop it too.
Greasy or oily substances. You may develop acne where your skin comes into contact with oil or oily lotions and creams.
Friction or pressure on your skin. This can be caused by items such as telephones, cellphones, helmets, tight collars and backpacks.
Acnes typically appears on your face, forehead, chest, upper back and shoulders because these areas of skin have the most oil (sebaceous) glands. Hair follicles are connected to oil glands.
The follicle wall may bulge and produce a whitehead. Or the plug may be open to the surface and darken, causing a blackhead. A blackhead may look like dirt stuck in pores. But actually the pore is congested with bacteria and oil, which turns brown when it’s exposed to the air.
Pimples are raised red spots with a white center that develop when blocked hair follicles become inflamed or infected with bacteria. Blockages and inflammation deep inside hair follicles produce cystlike lumps beneath the surface of your skin. Other pores in your skin, which are the openings of the sweat glands, aren’t usually involved in acne.
