Narrow-band ultraviolet radiation of 311:
1. Stimulate melanocyte hyperplasia (in the skin and hair follicles in the white spot of vitiligo, some melanocytes can escape from autoimmune damage, and 311 ultraviolet light can stimulate the remaining melanocyte hyperplasia).
2. Promote the production of vitamin D3, which is closely related to the functions of melanocytes and keratinocytes.
3. Activate pseudocatalase. Studies have shown that when a lot of skin diseases, including vitiligo pseudo hydrogen peroxide enzyme function of local skin is insufficient, lead to accumulation of local skin oxygen free radical damage melanocyte, the pseudo catalase in the skin can remove oxygen free radicals, formed to settle down in the skin cutin cell, melanocyte, etc to provide a clean living environment, excimer laser can activate the pseudo catalase, remove harmful oxygen free radicals to improve skin melanin cell survival environment.
4. Stimulate keratinocytes to synthesize and secrete inflammatory cytokines, and indirectly promote melanocyte proliferation and melanin synthesis.
