Pigment spots and age spots are an aesthetic problem. Unlike liver patches, which can turn into skin cancer over time, pigment spots are harmless. In the case of pigment spots, brownish skin discolorations occur, which are caused by a strong intercalation of skin pigments into the skin surface and the like. Also caused by long-term UV irradiation of the skin. They are also called sun spots. Solar spots (Lentigines solaris) or age spots (Lentigines senilis) are roundish to lenticular, brown hyperpigmentation which occur mainly at skin sites which are frequently exposed to the sun. On the back of the hand, on the sides of the forearms, on the forehead, on the forehead, and also on the décolleté. On the one hand, the decades-long influence of the UV radiation contained in it leads to over-active and intensified melanin being produced in the skin in order to protect the skin from the damaging influence of the UV radiation in the sunlight. On the other hand, the removal of the pigment also no longer functions smoothly. The result is that melanin accumulates in the skin and forms the unloved spots. In age spots, another dye is lipofuscin.
The so-called “pregnancy mask”, on the other hand, has its cause in the hormonal changes. These hyperpigmentation, which are usually referred to as melasma or Chloasma gravidarum / uterinum in the medical field, mostly affect the face and mainly the forehead, cheek and upper lip area. Pigment spots are harmless. However, it is important to distinguish them from malignant skin changes such as malignant melanoma (black skin cancer) and its precursors with a dermatologist.
