Pigmentation spots are caused by certain skin cells called melanocytes, which produce the skin pigment melanin. Melanin is a natural UV protector and is responsible for our tan. When excessive melanin forms in certain areas, spots appear. There are various triggers that can promote overproduction of melanin: these mainly include sunlight, genetic predisposition, hormonal influences, aging processes, as well as skin injuries or inflammations. In natural cosmetics, there are various active ingredients that can help reduce hyperpigmentation and even out skin tone. These include AHA and BHA fruit acids, retinol / vitamin A, bakuchiol, vitamin C, niacinamide, or bisabolol. And very importantly: consistent sun protection.
