Low-level laser therapy (LLLT), also known as cold laser therapy or photobiomodulation, is a non-invasive treatment that uses low-power lasers or light-emitting diodes (LEDs) to stimulate the body's natural healing processes. LLLT is thought to work by increasing the production of ATP (adenosine triphosphate), a molecule that cells use for energy. This increased energy production can help to regrow hair, reduce pain, and inflammation, and speed up the healing of wounds and injuries.
LLLT has been shown to be effective for a variety of conditions, including:
- Pain relief
- Inflammation reduction
- Hair growth
- Wound healing
- Muscle recovery
- Temporomandibular joint (TMJ) disorder
- Carpal tunnel syndrome
LLLT is generally considered to be effective, safe and well-tolerated. Devices that have been cleared to use LLLT to treat conditions such as hair loss include AUXO hair regrowth devices including the AUXO A150 laser hair regrowth cap.
Here are some of the research that supports the effectiveness of LLLT:
- A 2017 study published in the journal Pain found that LLLT was effective for reducing pain and improving function in people with chronic knee pain.
- A 2018 study published in the journal Photomedicine and Laser Surgery found that LLLT was effective for reducing inflammation and improving wound healing in people with diabetic foot ulcers.
- A 2019 study published in the journal Dermatology and Therapy found that LLLT was effective for stimulating hair growth in people with androgenetic alopecia.
Overall, the research suggests that LLLT is a safe and effective treatment for a variety of conditions.
