Less melanin means less protection from the sun’s rays. This raises the risk of wrinkles, uneven texture, and discoloration. Increased risk of skin cancer. The high risk of sun damage also increases your chances of developing skin cancer.

Does melanin decrease with age?

The number of melanocytes producing melanin per unit surface area of the skin decreases by about 10% to 20% per decade. The development of new melanocytic nevi also declines, from a peak between ages 20 and 40 to near zero after age 70.
