Hyperpigmentation – diffuse or focal deposition of pigment in the skin, leading to a darkening of the color of the entire surface of the body or individual areas of the skin. Hyperpigmentation of the skin can be caused by various physiological and pathological causes, and therefore the following types are distinguished: freckles, melasma, chloasma, perioral pigmented dermatitis, secondary hyperpigmentation, etc. To determine the causes of hyperpigmentation, you need to consult a dermatologist, endocrinologist, or gastroenterologist. Treatment of hyperpigmentation may include treatment of major diseases and cosmetic procedures (chemical and laser peels, photo-rejuvenation, etc.). The term "hyperpigmentation" refers to an excessively intense coloration of certain areas of the skin in comparison with the color of the skin. This condition occurs due to an increased concentration of pigment substances contained in the cells of the epidermis.
