Laser Therapy (Low-Level Laser): How It Works and Who It Helps

Low-level laser therapy, also called photobiomodulation, uses light at specific wavelengths to try to reduce pain and inflammation. It doesn't cut or heat tissue like a surgical laser. Evidence supports it for a few conditions and is weaker for others, so it's an optional add-on rather than a core treatment.

How it's meant to work

Light at red and near-infrared wavelengths is absorbed by cells, and laboratory studies suggest it can affect cellular energy production and inflammatory signalling. In practice, a small probe or cluster head is held over the area for a set time. It's painless, and protective eyewear is worn.

What the evidence shows

Some trials show short-term pain reduction in conditions such as neck pain, knee osteoarthritis and certain tendinopathies, and it has been studied for oral mucositis and wound healing. Results depend heavily on dose, and many studies are small. Other trials find little benefit.

The honest position is that laser therapy may help some people as part of a broader programme. It shouldn't replace exercise, activity modification or medical care.

Precautions

Laser is not used over the eyes, over active cancer, over the thyroid, or over a pregnant abdomen. It's used with caution over tattoos and areas of reduced sensation. If you take medicines that increase light sensitivity, let us know.

Please confirm with the clinic whether laser therapy is currently offered before booking specifically for it.
