How to treat vitiligo with laser

summary

In the early days, I grew some small white spots on my hands and arms, and I didn't care much about them. But later, the area of white spots became larger, and the symptoms became a little more serious. One check was vitiligo. Next, I will tell you how to treat vitiligo with laser?

How to treat vitiligo with laser

First: ultraviolet treatment, also known as laser treatment, is generally not recommended. Laser treatment causes great damage to the skin. After long use, it is easy to burn the skin and cause skin atrophy. At present, there are many treatments for vitiligo, different conditions, individual differences, treatment methods are not the same, it is recommended to check clearly, and then symptomatic treatment, in order to achieve the desired therapeutic effect.

Second, ultraviolet radiation can directly kill pathogens or change the living environment of microorganisms and inhibit their growth and reproduction. The bactericidal effect of ultraviolet is related to its wavelength, and the bactericidal ability of different wavelengths is different. Those above 300 nm have almost no bactericidal ability. Those below 300 nm increase bactericidal ability with the shortening of wavelength. Those between 250 and 260 nm have the strongest bactericidal ability, and then decrease. This is called ultraviolet bactericidal curve.

Third: the sensitivity of various bacteria to different wavelengths of UV is different, Staphylococcus aureus to 253. 7 nm UV is the most sensitive. Ultraviolet radiation can accelerate the clearance of inflammatory mediators, alleviate hypoxia and acidosis. Generally, the improvement of blood circulation caused by ultraviolet erythema reaction is delayed, and blue violet light is the immediate effect.
