During the summer, the whether is very hot, when we expose under sunshine too long, we are easily to get sunburn especially at outdoors. In this article I will introduce how does the sunburn cause the vitiligo? We know that vitiligo occurs when melanocytes die or stop producing melanin — the pigment that gives your skin, hair and eyes color. The involved patches of skin become lighter or white. The vitiligo may caused by the immune system attacks, and family history, or trigger by the sunburn, or stress.
Large amount of the clinical statistics indicates that incipient of the vitiligo is usually at the sunburn region. We know that the pathology of the vitiligo is mainly because of melancytes loss partial or total function, it leads that the there are less melancytes and black particles at the epidermis of skin, the basal layer of skin totally loss of the dopa pigment positive melancytes.
After exposure the blazing sun, the melancytes are hyperactive. It causes the melancytes over consumed and function declined. Moreover after the blazing sun burn, the cell will form some intermediate substance. When intermediate substance accumulates too much, it will damage the melancytes. So that’s why it will cause the melancytes.
Repeated exposure to UV radiation — whether from the sun or a tanning bed — increases your risk of premature skin aging and skin cancer, and vitiligo. here are some suggestions to prevent the sunburn.
