Brown patches of pigmentation as a result are the visible result of a
locally circumscribed overproduction and accumulation of the pigment
melanin, which is responsible for skin color. Melanin pigment-forming
cells of the skin, the melanocytes formed and passed on to the
surrounding skin cells. The strength of melanin formation is both
hereditary and determined by the age of the people and depends on
various environmental conditions (eg the UV rays of the sun), or
inflammation or irritation of the skin.
An overabundance of sunlight caused not only premature skin aging but also pigment irregularities. Certain substances called photosensitizers (perfumes, certain medications, St. John's wort), pimples, boils, abscesses, burns, surgery, laser treatments and sclerotherapy for varicose veins increase the risk pied hyperpigmented skin areas.
• Age:
From the 40th Age occur in clusters in the melanin formation of irregularities. With inadequate protection, the so-called liver spots increase in number, size and intensity with age.
• Pregnancy / Birth control pill / hormone replacement treatments:
Hormonal changes, eg during pregnancy, and estrogen treatments also favor the occurrence of pregnancy hyperpigmented areas of the face patches (chloasma, melasma =). The skin areas where the brown stains occur most often are the cheeks, forehead, upper lip and chin area, which is of smaller individual patches to all the areas mentioned anything is possible.
