Skin dyschromia (Greek Dys- + chroma - color, coloring) - changes in skin color. Skin pigmentation is caused by the presence of four pigments: brown - melanin, which is deposited mainly in the basal layer of the epidermis; yellow - carotene, which comes from food and accumulates in the keratinocytes of the epidermis; red - oxygenated hemoglobin (oxyhemoglobin), which ends up in the capillaries of the skin; blue - reduced hemoglobin (deoxyhemoglobin), which is found in skin venules.
Persistent skin dyschromia is a pronounced cosmetic defect, in which hyper- and depigmented spots in themselves are the main cause and stimulator of serious psychological disorders, which, in turn, support skin dyschromia. Often, it is the desire to get rid of dyschromia that is the only incentive that forces the patient to go to a medical facility. Therefore, to bring him out of a state of psychological maladaptation, one of the main conditions is the elimination of unevenness in skin coloring.
