Vitiligo is a very cruel disease, the treatment of this disease is not effective for every patient, because each person’s body quality is different, the changes that occur in the body of the drug effect is also different, so it is necessary to study more treatment methods to reduce the burden of patients. Studies have found that narrow wave UVB has better efficacy and less adverse effects on vitiligo.
Vitiligo is one of the world’s skin disease stubborn, the earth’s people of all colors, all kinds of ethnic groups can get this disease, medical professionals according to the incidence probability (1-2% of the population) calculation, our patients in more than ten million people. This is a very good way to get the most out of your life.
At present, the cause of vitiligo is still not very clear, subject to the limitations of technology and other reasons, the treatment of this disease is also more difficult, patients lose confidence in treatment and even despair, the medical profession is also racking their brains. With the development of science and technology, extensive communication in the medical community and a large number of clinical practice, scientists have researched a variety of treatment means, this disease in the early stage of the onset of treatment rate is still relatively high, using narrow-wave UVB phototherapy system to treat this disease, some patients have achieved good results.
UVB is a wavelength of 320nm-290nm ultraviolet light, is the most active part of the biological activity of ultraviolet light. It is found that UVB of about 310nm has the best therapeutic effect on skin diseases, and the erythema effect is relatively small, so the narrow wave UVB (narrowband UVB, NB-UVB) with a wavelength of about 311nm, which is produced after filtering out other wavelengths of UVB, can be produced and widely used in the treatment of skin diseases, and has achieved good efficacy in the treatment of vitiligo and psoriasis, which has been confirmed to be It is safe and effective, and can be applied to children as well.
There have been a large number of clinical studies at home and abroad, and it was found that the efficacy of narrow-wave UVB on vitiligo is better than that of PUVA method.
In the early stage of vitiligo, the efficacy of various treatments is good, with the prolongation of the disease, the efficacy will gradually decrease, so it is recommended to receive narrow-wave UVB treatment early.
