Question

What is the most important function of melanin?

• A. Causes the skin to be cooler
• B. Increases the amount of blood vessels
• C. Strengthens the skin or eyes
• D. Absorbs harmful radiation

Answer 1

The correct option is D

Absorbs harmful radiation

Melanin is responsible for skin colouration and is an effective absorber of light. It is able to dissipate over 99.9% of absorbed UV radiation. This is the reason why lighter skinned people have more chances of suffering from skin cancer when compared to people with darker skin.
