Apart from aesthetic inconveniences, pigment spots (or hyperpigmentation) are harmless. They usually settle on the areas most exposed to the sun (face, décolleté and hands) from the forties, and sometimes earlier. Often mistakenly called “age spots”, they are above all a sign that the skin can no longer effectively counter the harmful effects of ultraviolet rays or (we have recently known) the blue light given off by digital screens. They are in fact caused by an excessive production of melanin in the epidermis in the places most damaged by these rays: the clusters of pigments thus formed migrate to the surface of the skin.
The good news is that it is possible to prevent the appearance of these marks or to make them less visible without going to the dermatologist.
