308 excimer laser treatment technology, its single 308nm wavelength is considered to be the best wavelength of ultraviolet light for vitiligo treatment, which can make the skin melanocytes increase in size, dendrites lengthen, tyrosinase activity increases, and melanocyte synthesis black ability is enhanced.
The 308 excimer laser light source, which acts directly on the white spot area, promotes T lymphocyte apoptosis and solves the problem of melanocyte destruction from the root.
The specific principles of excimer laser treatment for skin diseases are: 1, induce T-cell death and improve local immunity (the direct cause of vitiligo is the killing of melanocytes in the skin by T-cells settled in the skin).
2, stimulate melanocyte proliferation (skin and hair follicles will remain part of the melanocytes that escaped autoimmune damage, excimer laser can stimulate the residual melanocyte proliferation).
3.Improve local microcirculation and promote melanocyte synthesis of melanin.
4.Promote vitamin D3 and melanocytes, keratin-forming cell function is closely related.
5, activation of pseudo-peroxidase. Vitiligo within many skin diseases, local skin in the pseudo-peroxidase can remove oxygen free radicals, to settle in the skin keratinocyte melanin to provide a clean living environment, excimer laser can be activated by activating pseudo-peroxidase, remove the harmful oxygen free radicals living environment.
