Low-level laser therapy (LLLT), also known as cold laser therapy, uses low-power lasers or light to provide medical benefits. It is called “cold” laser because the light intensity is low enough that it does not heat or damage tissues.
Unlike high-powered lasers that are hot and invasive—capable of cutting tissue like a knife—low-level lasers are non-invasive and painless.
Uses of Low-Level Laser Therapy
LLLT is utilized for a variety of treatments, although its exact mechanisms are not fully understood. Common uses include pain relief, reducing inflammation from injuries or chronic diseases, promoting wound healing, and even stimulating hair growth.
Peer-reviewed research supports its effectiveness for these applications. Since LLLT is painless and well-tolerated by patients, its use is growing. It is also an FDA-approved therapy.
How Does Low-Level Laser Therapy Work?
During LLLT, specific wavelengths of light—between 600 and 950 nanometers—are applied to body tissue. The tissue absorbs this light, triggering cellular changes that reduce inflammation and promote healing.
What Does It Feel Like?
LLLT typically does not produce any sensations. There is no pain, heat, or vibration, which makes its therapeutic effects all the more remarkable. Research into low-level laser therapy is ongoing, with many clinical trials currently underway worldwide.
