Cold Laser Therapy, also known as Low Level Laser Therapy (LLLT), is a revolutionary, non-invasive treatment that harnesses the power of light to promote healing, reduce pain, and enhance tissue regeneration. Unlike surgical lasers, Cold Laser Therapy does not cut, burn or destroy tissue. Instead it delivers low-intensity light to stimulate cellular repair and natural biological processes to relieve pain, promote healing, reduce swelling or stimulate and enhance cell function. The result is pain relief for a variety of conditions plus accelerated healing.
As well as Cold Laser Therapy’s technical name of Low level laser therapy (LLLT) the therapy is also known as photobiomodulation (PBM) as well as red light therapy.
In all cases, the treatment is non-invasive with the laser wavelength of light used emitting no heat, sound, or vibration.
Low Level Laser Therapy has been cleared by various regulatory bodies around the world for treating a range of medical conditions ranging from rheumatoid arthritis to oral mucositis. The therapy is also an excellent adjunct to many more traditional treatment approaches and growing in popularity. There are also some hard-to-treat conditions where cold laser is the goto solution.
