1.If your body makes too much melanin, your skin gets darker. 
2.If your body makes too little melanin, your skin gets lighter. Vitiligo is a condition that causes patches of light skin.
3.Melanin is the natural pigment that gives our skin, hair and eyes their color. 
4.Vitiligo is caused by a loss of pigment in the skin, due to destruction of pigment-forming cells known as melanocytes.
