How to identify brown spots (solar lentigines) ?
Brown spots (solar lentigines) are areas of hyperpigmentation that form light to dark brown spots visible on the surface of the skin. The hyperpigmentation observed is often the result of an accumulation of melanin, the pigment produced by melanocytes to protect the skin from the effects of the sun.
This accumulation in excess of melanin has several origins. It can be due to age: brown spots appear from the age of 30 and most often around the age of 45. Also, prolonged exposure to the sun, hormonal changes or genetic predisposition are the most common causes. Brown spots (solar lentigines) can appear several years after overexposure to the sun.
