What causes acne?Acne vulgaris, the medical term for putting surface acne is the most common skin disease. It is so common that nearly eighty-five percent of the people will give rise some form of acne at some quantify between the ages of twelve and twenty-five years. Although there atomic number 18 several theories closely what causes acne, medical doctors generally agree that acne is a by-product of hormonal changes in the body.At puberty (that period of life when a child develops secondary winding sex characteristics), increased levels of androgens ( commonly referred to as the male hormone) cause the sebaceous glands to stick to much sebum. The sebaceous glands lie just beneath the skins surface. They produce an oily substance called sebum, the skins natural moisturizer. These glands and the blur follicles (the tube like structures from which hair develops) within which they be found are called sebaceous follicles. These follicles blustering into the skin through pores . When excess sebum combines with dead inept skin cells a hard plug, or comedo is formed. If comedones are open to the surface, they are called blackheads. Comedones that are closed at the surface are called washrag heads. Plugged follicles can buoy rupture internally, resulting in a discharge of their contents into the environ tissues. A comedo is the mildest type of acne.Moderate and severe rabble-rousing types of acne are the result of plugged follicles being invaded by the bacteria that normally lives on the skin. The role of the bacteria is unclear. Bacteria may act by causing chemical reactions in the sebaceous fluid, leading to the release of actually irritating compounds called fatty acids. These in turn cause inflammation that increases aptitude to infection. A pimple forms when the damaged follicle weakens and bursts open, releasing a substance (sebum, bacteria, and skin) into the surrounding tissues. Pimples that are near the skins surface and are inflame are cal led papules. When pimples are deeper they are called pustules. This process begins an inflammatory response that sets the tier for the development of acne.Specialists are unable to detect the exact cause of acne, exclusively there are many risk factors that have been identified with the constituent of developing acne. Diet does not cause acne, but certain foods can cause flare-ups. However, eliminating certain foods, particularly chocolates and fats, appear to improve some cases of acne. Teenagers are more likely to develop acne, due to hormonal changes they experience. Boys tend to develop more severe acne than girls, as well as more often.
