What is the primary cause of vitiligo?

The primary cause of vitiligo is related to genetic factors. Vitiligo is a skin condition characterized by the loss of pigment cells (melanocytes), leading to lighter patches of skin. While the precise cause of vitiligo is not fully understood, it is believed to be an autoimmune disorder where the immune system mistakenly attacks the melanocytes. Genetic factors play a significant role in the development of the condition, as it is often seen to run in families. This suggests a hereditary component that may predispose individuals to developing vitiligo.

In this context, sun exposure, peeling, and infections do not have a direct role in causing vitiligo. While UV exposure can affect the skin's appearance and may impact those with existing vitiligo, it does not initiate the condition itself. Peeling refers to the exfoliation of skin, which is not a cause of vitiligo, and infections, although they may trigger or exacerbate symptoms in some skin conditions, do not contribute to the initiation of vitiligo. Understanding the genetic basis of vitiligo can help in recognizing the need for appropriate management and support for individuals affected by this condition.
