The brown spots are often hereditary or caused by the sun exposure. There are 3 types :
- Lentigo : also referred to as age spots or sunspots. When we expose ourselves to the sunrays, the cells that produce melanin increase. This is the reason brown flat spots appear on areas that are most exposed to the sun, such as the face, neck, cleavage and the back of the hands.
- Melasma: also called the mask of pregnancy. These brown spots are caused by hormonal fluctuations, for example, following a pregnancy, oral contraceptive use, or hormone therapy. They may also be related to taking photosensitizing medications, genetics and sun exposure.
- Seborrheic keratosis: it is the only spot that is not caused by the sun exposure. It is a flat or raised growth and its texture sometimes resembles that of a wart. They are linked to genetics and appear after 30 years.
The effectiveness of many creams sold in department stores is limited if the condition is at an advanced stage. Only a doctor can diagnose a skin pigmentation disorder before it is treated, making sure that it is not a type of skin cancer such as melanoma. Knowing that it is possible to eliminate the appearance of the discoloured skin patch, during the consultation the doctor will be able to suggest the most appropriate treatment.
