Question and answer
Q: Why is there an increased production of melanin when there is increased sun exposure?
A: Cells called melancytes that lie deep in the epidermis produce a pigenment, called melanin, that gives skin color. [ Exposure to ultraviolet light- from sun or tanning lamp-causes melanocytes to produce more melanin, which they pass along the skin above them, yielding suntan. ]
