nb-uvb

In the past, most doctors used PUVA equipment. This method required PUVA treatment combined with psoralen drugs. However, his side effects were that most people could not stand the NB_UVB research team members by maximizing the release of narrow-wave UVB rays. The above problem is solved by minimally exposing the skin to other unwanted UV rays. (The wavelength of 311nm---312nm is the most effective part of natural sunlight)

This greatly reduces the chance of vit patients being injured by UV rays in the use of optical therapy. (At the same time, it avoids the side effects caused by taking psoralen drugs in traditional PUVA treatment, because NBUVB does not need any auxiliary drugs.) These make NB_UVB accepted and popularized by doctors and vit patients.

Moreover, NB_UVB can be used in the home, which also facilitates the treatment of vit. As for how to choose the type of equipment, radiation distance, irradiation time, and dose to be used according to each person's specific conditions.

NB_UVB eliminates other excess and harmful ultraviolet rays by releasing ultraviolet rays of effective wavelength (311 nm - 312 nm), while the radiation range of conventional UVB lamps (280 nm - 330 nm). Clinical studies have shown that the most effective treatment for vit has a ray wavelength of 295 nm - 313 nm, but if the wavelength is below 300 nm, it may cause skin cancer, burns, or other diseases, and 311 nm - 312 nm is considered to be the safest range.
