What is the primary cause of vitiligo?

The primary cause of vitiligo is actually linked to genetic factors, which play a significant role in the development of this condition. Vitiligo is characterized by the loss of skin pigment due to the destruction of melanocytes, the cells responsible for producing melanin. This process is often influenced by an individual's genetic makeup. Family history of autoimmune conditions can increase the likelihood of developing vitiligo.

Other factors such as sun exposure, peeling, or infections do not serve as primary causes of vitiligo. Sun exposure can exacerbate the appearance of vitiligo in affected areas but is not a root cause. Peeling, which might refer to skin exfoliation practices, does not contribute to or cause vitiligo. Similarly, while certain infections can influence skin health, they are not responsible for the onset of vitiligo. Understanding the impact of genetic factors is essential for recognizing the nature of this skin condition and how it manifests.
