CAUSES
It typically presents in adolescence, affecting 80% of this population group. due to an interaction between hormones, sebum and bacteria living on the skin or inside of it and also in the hair. During puberty, increases the activity of the sebaceous glands of the skin with excessive sebum production. Often the fat dry, scaly debris and bacteria accumulate in the pores of the skin forming a pimple, which prevents the sebum from hair follicles to flow through the pores. If the blockage is incomplete blackheads are formed; if it is complete, white spots appear.
However there are some special forms of acne that can affect new-borns or adults exposed to certain industrial products (occupational acne), or people taking certain medications such as oral corticosteroids (acne drug-induced), making them less frequent clinical forms the classic teenage acne.
SYMPTOMS OF ACNE
Acne signs and symptoms vary depending on the severity of your condition:
* 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)
Why treat acne?
Myths about acne are as common as the skin problem. One common myth is that you have to let acne run its course.
Dermatologists know that letting acne runs its course is not always the best advice.
Here's why:
* Without treatment, dark spots and permanent scars can appear on the skin as acne clears.
*Treating acne often boosts a person’s self-esteem.
* Many effective treatments are available.
Risk factors
Risk factors for acne include:
- Hormonal changes. Such changes are common in teenagers, women and girls, and people using certain medications, including those containing corticosteroids, androgens or lithium.
- Family history. Genetics plays a role in acne. If both 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 oily lotions and creams or with grease in a work area, such as a kitchen with fry vats.
- Friction or pressure on your skin. This can be caused by items such as telephones, cellphones, helmets, tight collars and backpacks.
- Stress. This doesn't cause acne, but if you have acne already, stress may make it worse.
