Low level laser therapy principle:
    Low Level Laser Therapy (LLLT) is the therapeutic application of laser light at a low intensity. It is a non-invasive treatment that uses a light source that generates coherent (Laser) and non-coherent (LED) light wavelengths that are effective through photochemical reactions in cells, rather than through a thermal effect. These wavelengths are specifically in the red (visible) and near infrared (invisible) range. The visible light ranges, while beneficial, are limited by their shallow penetration of 1-3 mm. Invisible or near infrared light range penetrates much deeper (clinical results indicate up to 10 cm). The process enables Lasers to carry electrons throughout the body to restore damaged cells and the problems that arise from those damage cells, and to provide pain relief. Both coherent and non-coherent light with the same wavelength, intensity and dose provide the same biological response.

Applications:

Wound repair

Treatment advice:
  It's recommended to use 1-2 times a day for 4 weeks,20 minutes each
time (according to your physical condition).The light therapy must be
applied directly on the skin,without clothing covering and without
distance from the skin,and please try different modes:pulsed and
continuous may be different for different conditions (pulsed is better
than continuous for most applications except nerve regeneration),and
please note that the results will be better after 4 weeks of persistent
use at 100%full power 1-2 times a day.each time each part of the body
is irradiated for about 20 minutes.You will benefit from consistent use.
