Also, wear sun safe clothing and sunscreen, avoid excessive stressful situations and improve nutrition and diet to prevent the spread of vitiligo.

Is it good or bad to have melanin?

Melanin is a natural pigment found in most organisms including humans. People with high amounts of melanin tend to have darker skin, whereas people with less melanin have lighter skin. Melanin acts as a physical barrier that scatters UV radiations and reduces the UV penetration through the epidermis and protects from UV induced damage like sun-induced skin cancer.
However, melanin can also have toxic properties, especially after exposure to UVR. At present, the clinical significance of deleterious effects in carcinogenesis is not known.
