The application of NB-UVB phototherapy to dermatological treatment is a milestone event in dermatological therapeutics. The application of NB-UVB has epoch-making significance, especially in vitiligo treatment, before this method was introduced, doctors tried all kinds of methods such as oral medication, topical medication, epidermal transplantation, melanocyte transplantation, etc., but each method has its limitations and the efficacy is always unsatisfactory. The narrow-spectrum UVB of 311nm has a weak response to treat erythema and eliminates the cancer-inducing and photoaging effects produced by broad-spectrum UVB. A large number of clinical studies and data (MATE analysis) show that the average recolored area is >50% after 30 treatments with 311nm NB-UVB.
Nowadays, NB-UVB is more popular in the field of dermatology treatment, if you are lucky enough to live near a large hospital, using large NB-UVB phototherapy instrument to treat the best effect, but friends located in remote counties and towns do not need to be pessimistic, many large hospitals are equipped with home type phototherapy instrument, the effect is also quite satisfactory and very convenient to use. 311nm narrow spectrum medium wave UVB in the hands of professional doctors is a favorable The actual fact is that you can find a lot of people who have been in the marketplace for a long time, and you’ll be able to find a lot of people who have been in the marketplace for a long time. Otherwise, there will be excessive local treatment response and rapid development of lesions; if the dose is insufficient, it will not play a therapeutic role, but cause adverse consequences.
2.Energy accumulation and sequential increase: NB-UVB restores skin color by upregulating tyrosinase activity, awakening inactive melanocytes to proliferate and promoting melanin formation. This process depends on the gradient change of energy accumulation of NB-UVB, in other words, the treatment dose is increased or decreased in an orderly manner to make it effective. This is the key to the success or failure of the treatment, so it needs to be used under the guidance of professionals.
3, treatment interval and end point: the treatment of any method is not constant, and so is NB-UVB treatment. If there are obvious erythema, blistering and other treatment reactions during the treatment process, it indicates that the dose is too large or the individual’s tolerance threshold for NB-UVB is too low. When no recoloration is seen after 30 consecutive treatments, the decision should be reported to the physician, and whether or not it is effective should be reported to the physician after 50 or more consecutive applications. Any unexplained changes in the local skin should also be reported to the physician. When the treatment area is completely recolored or used more than 100 times, the doctor should decide whether to terminate the treatment.
4. Keep your eyes open to avoid being cheated: In the internet era, various information is mixed, and unscrupulous businessmen often take advantage of people’s psychology of convenience and cheapness to sell counterfeit products, posing as NB-UVB with broad-spectrum UV lamps, which have clear effects of inducing skin cancer and causing photoaging.
