Difesa naturaleThe human body has a fantastic ability: when exposed to sunlight, it produces melanine. It is a natural protection factor against ultraviolet rays and gives us that beautiful bronze suntan. Melanine is produced by melanocytes, which are found in the basal epidermal layer. Their role is the synthesis of melanine, which is then stored in melanosomes. The latter migrate into the epithelial cells, where they create a protective layer that reflects more than 70 % of ultraviolet rays.
