The most important problem of vitiligo is the loss of melanocytes in the skin and hair follicles or the decrease in function of melanin production causing skin pigmentation loss white spots. From this point of view vitiligo lesions are mainly in the skin and not directly related to the blood.
The actual fact is that the actual person’s parts are closely linked to form an inseparable whole. The skin needs to be nourished by the blood, and the changes in the various components of the blood will also affect the structural integrity and normal function of the skin. From the current research results, some vitiligo patients have neuroendocrine and immune system changes, and there are antibodies against melanocyte components in the blood, and these antibodies can cause the destruction of skin melanocytes, which may be related to the formation of white spots. From this point of view, vitiligo patients do have certain abnormalities in their blood.
