AnswerClick to flip back
A
Skin may vary frequently in the amount of melanin it contains.
💡 Explanation:
Ultraviolet radiation from the Sun stimulates melanocytes in the skin to produce more melanin, which in turn makes the skin browner. This seasonal tanning is most noticeable among light complexioned people. It has the effect of shielding the inner skin.
