Acne is characterized by blockage of fat and keratinized epithelial cells of the excretory ducts of the sebaceous glands and hair follicles, as well as inflammatory processes in them. Rash localized mainly on the face, back, upper anterior chest, at least – in the neck and shoulder girdle. Their appearance is not connected, as previously thought, with violations of hygienic rules for skin care. The processes do not arise independently, but against the background of various changes and irregularities in the body. Therefore, the local manifestation of disorders of a general nature is called acne. It occurs in different age groups and is often a complication of mixed or oily seborrhea.
Existing methods and preparations for the treatment of acne in many people are effective only in cases of their correct use, which is possible with an understanding of the pathogenesis (developmental mechanism) of the disease and the causes of it.
