Explanation:
Detailed explanation-1: -UVA radiation is what makes people tan. UVA rays penetrate to the lower layers of the epidermis, where they trigger cells called melanocytes (pronounced: mel-AN-oh-sites) to produce melanin. Melanin is the brown pigment that causes tanning.
Detailed explanation-2: -What Causes Increased Melanin Production? UV-A rays from the sunlight penetrate into the lower layers of the epidermis and trigger the melanocytes to produce more melanin. Melanin is produced as a defence mechanism. Sunlight is the major cause of increased melanin production.
