Abstract:
With advance research over last few decades skin diseases like vitiligo,psoriasis,baby jaundice etc. are treated with phototherapy. The stable vitiligo can be treated with the excimer lamps based on excitation of molecule like XeCl. It is used in producing UVB with 308 nm wavelength which has high penetrating power and is found to be useful in accelerating melanin formation activity. The depigmented skin showing white patch can be repigmented to achieve normal skin colour. The UVB units are available in various shapes and sizes to cover entire body surface or targetting to a small skin area like fingers or toes. Skin care with light sources is in practice since quite long. Systematic study of lamps having different wavelengths made it possible to bifurcate the wavelengths to be used for various diseases.
