Scars are formed in those places where there is the strong damage and fracture of tissues. In a skin it is the copulative tissue surrounding hair follicles, and sometimes - hypodermic cellulose.

Scars arise during response of tissues to damage, process of an adhesion of wounds. When something collapses, formed "hole" is closed up by those materials of which the copulative tissue is constructed. First of all, it is a collagen. Process of an adhesion and a cicatrization of each damage lasts about one month.

"Repair" of tissues descends in terminating stage of an inflammation. At an inflammation of a tissue are always damaged. When it is enough fracture greater, or process of an adhesion is broken, the former structure of a tissue sometimes is not recovered. The scar is formed on its place.

At acnes are formed two phylums of scars - atrophic and hypertrophic. The arrest of development means a deficiency of propagation, and a hypertrophy - excess. The strong or feeble ability of a copulative tissue form a collagen can to be a specific feature of the person. On different fields of a skin formation of a cicatrical tissue goes with different intensity, it depends on blood supply of the yielded area. For example, on cheeks occurrence of scars more possibly, than on temples.

At atrophic scars formation of a collagen goes with small intensity, it suffices only on repair of walls of "hole". Such holes are the flaws of the skin which have arisen after fracture of a follicle and a copulative tissue surrounding it, and even hypodermic cellulose. Fracture can be greater - and scars can be deep and wide. It is characteristic for heavy shapes of disease.

Besides attempts to squeeze out and dissect spots invoke additional damage of tissues - so, and occurrence of scars. Thus in a wound the infection contamination that else complicates an adhesion can be brought.

At hypertrophic scars formation of a collagen goes more strongly, than it is required, and the scar rises above a surface of a skin. The expressed hypertrophic scars-keloids it is possible to expect at the people predisposed to such response at a genetical level. They have inborn features of synthesis of a collagen and formation of a scar goes more longly - for example, at many people with a dark skin.

Most the poor in scars - that they do not peter. They remain for a long time, and without treatment for ever. Scars cannot dissolve. Any treatment of scars includes their physical removal - bodily or stratums.

During an aging people lose a dermal collagen, approximately on 1 % a year, since 40 years. Therefore at older persons some scars become more appreciable, and others - are less appreciable.

The main thing that it is necessary to remember about scars are that at acnes they arise only as a consequence of an inflammation. The one who can prevent the strong inflammation, can avoid and occurrences of scars.

The main thing to make it, yet late.
