Vitiligo, also known as leukoderma, has complex and not yet fully understood causes. The main possible factors include: 1. Genetic factors: Genetic factors are considered an important cause of vitiligo. If there is a family history of vitiligo, the risk of developing the condition in offspring increases. 2. Autoimmune factors: The patient's immune system may attack and destroy melanocytes, leading to pigment loss and the formation of white patches. 3. Neurological and psychological factors: Psychological factors are closely related to the onset of vitiligo. Psychological trauma or excessive stress may affect the function of melanocytes. 4. Physical injury: Chronic friction, severe burns, or significant trauma to the skin may result in damage or destruction of melanocytes. 5. Vitamin deficiency: Deficiencies, especially in vitamin B12 and folic acid, may be associated with the development of vitiligo.
