Excimer Laser

The excimer laser uses a specific wavelength of 308nm and thus os a modified advance form of light therapy useful in various dermatology diseases. Traditionally light therapies used to be given either in the form of tablets followed by sun exposure or full-body light chambers. These had their own disadvantages especially in patients who didn’t require therapy for full body. Excimer laser creates a concentrated beam of ultraviolet light and is delivered in the form of painless shots over areas where the effect is needed. This makes excimer very targetted therapy.
