What causes acne?

To date, the causes of acne are poorly understood. But we know that the lack of hygiene, poor diet and stress, no doubt, increase the expression of acne, they are not provoking factors of acne.

Hormonal background. In adolescents, acne start to occur as a result of amplification of hormone production. During puberty and boys and girls increased level of androgens - male sex hormones, including testosterone. Testosterone causes the body to produce more sebum - a waxy substance that promotes moisturizing of the skin. In addition, androgens increase the production of keratin - a substance involved in the formation of hair and nails.

Bacteria. Excess sebum clogs the hair follicles of the funnel, especially those that are located on the face, neck, chest and back. The clogged follicles begin to grow bacteria. This process causes the formation of a skin on the surface of ferrous or whiteheads, i.e. non-inflammatory acne. Sometimes the follicle wall collapse under the pressure build-up. If this happens, sebum flows into nearby tissues and form ulcers formation, ie inflammatory acne, and sometimes cysts. Ruptured cysts leave temporary or permanent scars.

Despite the fact that the increase in androgens during puberty is considered to be a normal process, some doctors believe that acne outbreaks are associated not so much with androgens, but with a response reaction of the skin to increase the production of sebum. Propionic acne bacteria staphylococci and formed in healthy hair follicles. If the clogged follicles collected a large number of these bacteria, they may produce enzymes that break down sebum and cause inflammation. Some people are more susceptible to this reaction, other - less. The level of sebum, causing some people have only a couple of spots, while others provoke the appearance of large areas of the rash or even acute cystic acne.
