Vitiligo is a kind of depigmentation skin disease. Human skin is composed by epidermis, dermis, subcutaneous tissues and appendant organ. It can be divided to baser layer, prickle cell layer, granular layer, the transparent layer and stratumcorneum from inside to outside. These five layers are constituted of angle of yuan cell and dentritic cell. Dentritic cell has three kinds, and one of it is melanin cell. Melanin cell can take advantage of tyrosine to compound melanin under the promotion of tyrosinase. Because of the decrease and disappearance of tyrosinase activity of melanin cell in skin and hair follicle, there will be depigmentation disease in epidermis, which will be the direct reason to arouse leucoderma. And the melanin cell will be damaged and can not produce melanin any more. Also some experts find that vitiligo patients have a lower content of trace elements, such as copper, zinc, iron and etc. So it may be caused by the decrease of microelement and biological enzyme metabolism abnormity. In the treatment process, patients should have a correct understanding of vitiligo symptom and causes, then you can get specific treatment.
