UV Phototherapy and vitiligo

Type:Uv phototherapy Time:2018-10-25 15:09:42 Vitiligo may not be strange to everyone.I heard that ultraviolet light therapy can treat vitiligo, is it true?? Vitiligo is a common and frequent pigmented skin disease characterized by local or generalized pigmentation to form white spots. It is an acquired disease. White patches formed by skin pigmentation. The reduction or even disappearance of the number of melanocytes in the skin leads to the occurrence of vitiligo, and the specific mechanism is not clear. It is currently believed that there are several possibilities: abnormalities in nerve cell function produce substances that are toxic to melanocytes, and the immune system of the body functions to attack and destroy the defects of melanocytes or melanocytes themselves, forming some pairs in the process of melanogenesis. It has its own toxic by-products, and patients with vitiligo may have certain genetic defects, making melanocytes vulnerable to destruction. Ultraviolet light therapy stimulates the proliferation and migration of melanocytes. When melanocytes absorb UV energy, they can also stimulate the activity of tyrosinase, accelerate the oxidation and polymerization of tyrosine, and increase the principle of melanin synthesis to treat vitiligo. At the same time, keratinocytes can be promoted to release melanocyte proliferation and differentiation factors such as endothelin-1, fibroblast growth factor and the like to treat vitiligo. It can be seen that in the treatment of vitiligo, ultraviolet phototherapy still has a better therapeutic effect. When using the therapy device, I hope that everyone can use it in strict accordance with the instructions to avoid unnecessary trouble.
