hey mate here is your answer,.....
changing of skin colour because of the UV rays of the sun
A suntan is your body’s attempt to protect itself from the sun’s damaging UV rays. Melanin is the chemical responsible for skin darkening or tanning. 

Always wear a hat, sun protective clothing, and sunscreen when outside. Sunscreen should be reapplied every two hours.
