How to avoid getting vitiligo?

Genes may affect whether people develop vitiligo, as may having other diseases or disorders like diabetes and autoimmune conditions. People with vitiligo often have sensitive skin; whether or not good skin care practices will one day be proven to help prevent vitiligo is unknown, but it is always a good idea to practice sun safety. This includes wearing a sunscreen with an SPF (sun protection factor) of 30 or greater, wearing sunglasses, staying out of the sun during peak hours, and wearing protective hats and clothing.

Then these might be the signs of Vitiligo. They are spotted white areas wherein the pigmentation of the skin is lost. This condition arises when the pigment cells, also known as melonocytes, are destroyed leaving no melanin pigment under the skin. It can be observed that these patches are in symmetry on the both sides.
