describe Product plugged in Does not come with USB cable in the package Features The laser therapy device treats the fungal nail infection onychomycosis, which combines pulsed laser radiation and blue light energy to produce a synergistic therapeutic effect. Laser irradiation will penetrate the infected nail plate and target the disease-causing pathogens on the nail bed. In this way, the infection will be greatly reduced and gradually eliminated. Lasers produce coherent light energy of sufficient intensity and specific wavelength that, when projected into tissue, is absorbed differentially by the target material, generating heat that can destroy the tissue. Other tissue components are unaffected and therefore not affected. The compact design is lightweight and small enough to carry anywhere. Plus with the added of portable power, you're guaranteed to have your nail fungus treatment on the go; even on the go. Acts fast and results; nail fungus medication requires just 7 minutes of treatment per affected nail per day to see incredible results in just a few weeks. No other treatment provides nearly the same results in such a short period of time. Revolutionary Home Treatment; An innovative device now allows you to treat fungal nail infections in the comfort of your own home. No more appointments or visits to the doctor,on your own time and anywhere you like. Treat onychomycosis easily and painlessly; just place it on the affected nail, press the button and it will work its magic for 7 minutes, the nail fungus remover will automatically turn off when finished.
