The technique is called “cold” laser therapy because the low levels of light aren’t enough to heat your body’s tissue. The level of light is low when compared to other forms of laser therapy.

During this procedure, different wavelengths and outputs of low-level light are applied directly to a targeted area. The body tissue then absorbs the light. The red and near-infrared light causes a reaction, and the damaged cells respond with a physiological reaction that promotes regeneration.
