White patches emerge as a result of melanin loss in vitiligo, a chronic skin disorder. This happens when melanocytes—the cells that make pigment—are harmed or killed. Vitiligo is frequently linked to autoimmune mechanisms, in which the body's immune system attacks its own cells, even though the exact reason is yet unknown. Its onset is also believed to be significantly influenced by oxidative stress, environmental variables, and genetics. People of any age or background might be affected by the disorder, which can progress slowly or quickly. Based on the distribution of depigmented areas, it can be roughly classified into segmental and non-segmental forms. Although vitiligo is not contagious and does not directly endanger physical health.
