Cold Laser
Also referred to as Low-Level Laser Therapy (LLLT), cold lasers are not like surgical lasers that use heat to cut or cauterize tissue, and they also don't provide cooling effects. Cold lasers use low-intensity light to stimulate cellular repair without producing heat.
- Coherence and Precision: Cold lasers emit a coherent beam, meaning the light waves are synchronized and travel in a single direction. This allows the energy to stay concentrated as it travels deep into the body (up to 2-5 cm), rather than scattering like red and infrared light.
- Deep Tissue Targeting: Because it does not lose power through scattering, cold laser therapy is the "gold standard" for treating deeper issues like nerve regeneration, chronic joint pain (arthritis), and ligament injuries.
- Clinical Strength: Cold lasers have historically been used by medical professionals for rapid healing and long-term recovery, but many are becoming easier to use and have preset laser programs for at-home use.
