It has also been found that vitiligo is genetically related, with approximately 30% of cases found to have a family member with the disease.

Causes of vitiligo

At present, the exact cause of vitiligo is unknown. But it is assumed that it may be related to autoimmune reactions. (The body produces antibodies to antigens involved in the process of melanin production) or may stimulate nerve endings to cause the secretion of substances that destroy melanin cells. Or in the process of melanin production, there may be some accumulation of metabolites (Metabolite) that have the effect of destroying melanin cells. It is also believed that vitiligo is related to genetics, making the color-producing cells weaker and more prone to damage.

Spots may also be found on the mucous membranes lining various organs, such as the mouth, gums, genitals, nipples. Ginkgo Biloba has a beneficial impact on vitiligo.
