Acne vulgaris is a common skin disease particularly characterized for teenage period. For acne vulgaris occurrence is particularly important an increased secretion of sex hormones. A collection of dead skin cells, bacteria and dried sebum, leads to hair follicles clogging, which represents the beginning of the process of acne formation.
It seems to be in the form of white or black comedones (no inflammation) or as papules, pustules (inflamed present) and in serious cases also such as nodules and cysts.
Although acne are part of adolescence, can greatly affect the lives of adolescents and their self-esteem.
Acne vulgaris typically, occur in seborrheic areas of skin where there are more sebaceous glands and therefore more chances for oily skin: the scalp, forehead area just above the root of the nose, eyebrows, eyelids, nose crease to corner of mouth, the area between the chin and nose, on the chest, skin behind the ears, on the chest, between the shoulder blades, in groin and on the buttocks.
Comedones are small bulges with black cap (open, incomplete pore blockage) or white (closed, complete pore blockage). Comedones represent no inflammation form.
Papules or pustules (red and delicate bobbles) occur as skin inflammation in the hair follicle. Nodules and cysts are larger, painful bumps under the skin surface.
Acne vulgaris causes and risk factors
Sebaceous glands are located in the dermis, the middle layer of skin, and are attached to the hair follicles. On the surface of the skin secrete fat (mainly from triglycerides and fatty acids) and dead skin cells. If the follicles become clogged with dried fat, with dead skin cells and bacteria, the fat cannot be eliminated through the pores of the skin and the bacteria Propionibacterium acnes grow. These are as breakdowns of fat normally present in the hair follicle. The increase in breakdown products of fat leads to inflammation, resulting in pimples, cysts and sometimes as an abscess.
For acne occurrence are important mainly androgenic hormones (e.g. testosterone) and hereditary susceptibility to seborrhea (increased production of sebum).
Acne most commonly occur in young people between 13 and 15 age (80%), and sometimes even after 30 year. In the mid-twenty years, the production of hormones normally stabilizes and then these kinds of skin problems disappear spontaneously.
On the occurrence of acne can also affect other situations, where it is also a hormonal change (e.g., menstruation, pregnancy), or some drugs that stimulate the activity of sebaceous glands (especially corticosteroids and anabolic steroids) or use of some makeup, which clog the pores.
Less influence on the incidence of acne has oily food and chocolate. It also does not fully apply that is dirt that causes acne. Rubbing the skin and cleaning with aggressive soaps can only aggravate acne. Connection about gluten and acne.
