Low-intensity laser therapy
Cold laser therapy is low-intensity laser therapy, or laser therapy that uses low levels of light to stimulate healing. Unlike surgical or aesthetic lasers, the technique is called "cold" laser therapy because the low levels of light are not enough to heat your body's tissue. When compared to other forms of laser therapy, the level of light is not strong enough to destroy tumors and coagulate tissue.
Low-level light is applied directly to the problem area. The tissue then absorbs the light. In a basic sense, this leads to a biological or chemical reaction to red and near infrared light. Damaged cells have a physiological reaction that helps promote their regeneration.
During the procedure, you'll feel the device against your skin, but it creates no heat, sound, or vibration. Even better, it is completely noninvasive and painless. Most of the time, one treatment will take only a few minutes.
The main uses for cold laser therapy are tissue repair, relief from aches and pains, minor injuries and sprains, skin rejuvenation, wound healing, acupuncture, and inflammation.
