“Cold laser” is a nickname for low-level laser therapy or LLLT. The term differentiates from a surgical laser, which uses high frequencies of amplified light as an ultra-precise surgical cutting tool. A cold laser uses a lower frequency of amplified light. This laser beam doesn’t cut or burn the skin at all; instead, it passes right through it to a depth of up to several centimeters. There, the laser energy stimulates cell components called mitochondria to produce more of a substance called ATP. ATP is a vital raw material that gives cells the energy to repair themselves. By triggering ATP production, the cold laser helps damaged tissues heal more quickly and thoroughly.

The cold laser energy also relieves pain. The beam enhances circulation, helping excess fluid, inflammatory substances, and other waste products exit ailing tissues. This effect makes it a potent option for long-term pain management in inflammatory conditions.
