How does excimer light treat vitiligo

summary

Vitiligo is a localized or generalized depigmentation of skin and mucous membrane disease caused by local pigment cell destruction. Generally speaking, there is no significant gender difference in the incidence of this disease. The incidence rate of people with deep skin is higher than that with lighter skin. At present, the pathogenesis of this disease is complex, and the treatment methods are various. In the past, the disease was mainly treated with oral and topical drugs, but the curative effect was not sure. So 308 excimer therapy for vitiligo is more and more common. Now let's share it.

How does excimer light treat vitiligo

First, we often say that 308m excimer light belongs to the category of UVB, and its excimer filter blocks the unnecessary short wave ultraviolet light, so the light purity is higher, which shortens the treatment time in clinic, improves the treatment effect and increases the treatment safety compared with drug method and surgical method.

Second: in recent years, narrow-band ultraviolet B (NB-UVB) has been widely used in the clinical treatment of vitiligo with its good curative effect and less adverse reactions. It has obvious advantages in the treatment of vitiligo, such as fast onset, good curative effect, less adverse reactions, high safety, low treatment cost and so on.

Third: the wavelength of 08nm excimer laser is more single, but its light spot is small due to the limitation of its light source, so it can not be used for large area skin lesions, and the maximum area of 308 excimer laser spot is 264 cm2. Because of the need of optical fiber transmission, the cost of consumables is high. 308nm excimer light has no consumables. The purpose of clinical treatment is to control the development of skin lesions and promote the recovery of leukoplakia.

matters needing attention

The energy loss of 308n excimer laser is large due to the conduction of optical fiber, while the energy loss of 308n excimer laser directly irradiated by lamp is small. Although the effect of this method in the treatment of vitiligo is good, not all patients are suitable for this method. Patients should use it reasonably according to their own condition to have a certain curative effect.
