Hyperpigmentation affects a growing number of people. Under the action of the sun, hormonal variations and/or aging, pigmentation disorders take the form of spots, but also loss of homogeneity. This concerns the areas most exposed to the sun, such as the face, décolleté, legs and back of hands. These spots are caused by an excess of melanin, irregularly distributed.
There are different types of spots: melasma (pregnancy mask) due to a hormonal disorder, lentigo (sun spot) and senile lentigo, which is age-related and can be aggravated by the sun.
