Vitiligo patients develop white patches on the skin due to melanin deficiency as a result of the destruction of melanocytes in the skin. The early stage can be asymptomatic or simply show a localized lightening of the skin color. It is usually dotted or patchy, without scales on the surface, and the boundaries with the surrounding skin are not obvious, and most of them do not have self-conscious symptoms such as redness, swelling or pain. The actual fact is that you can find a lot of people who are not able to get a lot of money for the actual money. Vitiligo can appear on any part of the body, especially on exposed, frictional or skin folds, such as the face, neck, back of the hand, forearm, etc. The most important thing is that you can get a good idea of what you want to do. When early vitiligo occurs on the face, it needs to be distinguished from pityriasis simplex, generally through Wood’s lamp irradiation, observe whether grayish white light, if it appears, usually that is early vitiligo. Because vitiligo may be related to autoimmune system diseases, genetics, neurochemicals and other factors, so vitiligo patients are often accompanied by autoimmune diseases such as hyperthyroidism, autoimmune polyglandular syndrome, there may also be a family gathering phenomenon, but not all vitiligo patients will have the above conditions. If you need to work in an exposed environment, you should do a good job of sun protection and try to avoid exposure to the sun, trauma and other risk factors that can trigger vitiligo. Also proper supplementation of vitamin B, vitamin E and folic acid and antioxidants are helpful to prevent vitiligo.
