Cold laser is a noninvasive and non-thermal therapy in which a special type of light penetrates the surface of the skin as well as underlying tissues to stimulate natural healing in the body. The body's cells are exposed to photon energy, which in turn increases the cells' metabolism, helps to develop muscle tissue and collagen, improves blood circulation, stimulates tissue repair and the healing of wounds, and stimulates the nervous and immune systems.  Cold lasers are also used in acupuncture to stimulate the acupoints of the body without using needles.

The medical director of the Pain Clinic and Laser Center of Locarno, Switzerland, Zlatko Simunovic, M.D., F.M.H., writes: “Laser therapy [LLLT] is a natural and biological therapy, because even from early ages, man has considered the light of the Sun to be responsible for his health.  Human kind simply cannot live without the light, a fact proved by evident lack of light in the sick cell.”

Laser light restores health to just such an ailing cell.
