Dark spots are the sign of a pigmentation problem. They can take different sizes and shapes depending on the pathology. Among them, melasma (also known as pregnancy mask) appears as spots grouped together on certain parts of the face. Lentigines, hyperpigmented dark spots linked to age, affect areas that are frequently exposed to the sun.

Regardless of the type of dark spot, they can be caused by many different factors, not just skin ageing. Lightening skin treatments exist and can reduce their appearance.
