Xtrac Excimer 308-nm laser is a laser light source that delivers a specific wavelength (308 nm) of ultraviolet B (UVB) radiation. This new technology is a further development of narrowband UVB that delivers energy at a wavelength between 311-312 nm and has proven to be beneficial in the treatment of vitiligo and psoriasis. In this article, I will introduce you the mechanism of excimer 308-nm laser therapy in treating vitiligo.
Excimer 308nm laser treatment system can be said to be the peak of the laser therapy in treating skin disease. It integrate the 308nmXeCI excimer laser light resource, 154Hz quasi-continuous nano modulation, The latest liquid light transmission (LLG) and many of the world's top technology and so on. The treatment system uses is XeCI excimer gases. Clinical study have shown that the single wavelength of 308 nm was detected in the induce the T lymphocyte apoptosis for vitiligo and lesions of posoriasis is the best wave length, 308nm also is the strongest wavelength, the deepest can penetrate the leather shallow 1.5 mm. the medical use this principle, the laser direct radiate to the lesion part of skin this will make some relevant biological and chemical changes, it will facilitate the synthesis of melanin. So it reaches the treatment goal by use this 308nm. The 308nm exciser laser treatment system imported from the American original device. It referred as 308. A single frequency excimer laser, the wavelength of 308 nm, 30 ns pulse width (ns), single pulse energy density for 2-3 mj (millijoule)/cm squared, using liquid laser, optical fiber transmission can form 2 x 2 cm squared square spot, namely single treatment area for 2 x 2 cm squared.
Additionally, it is recommended for patients suffering from vitiligo for a long time since they cannot apply topical steroids for a prolonged treatment because of the side effects, especially on face and intimate areas. You have to look for professional treatment.
