Why red light actually works
Photobiomodulation has been studied in over 5,000 peer-reviewed clinical trials. Here's a fraction of what the research shows.
Skin & Collagen
A 2014 randomised controlled trial of 136 volunteers showed significant improvements in skin complexion, texture and intradermal collagen density after 30 sessions of red light treatment.
Hair Growth
A 2013 double-blind study using 655nm red light therapy in 44 men showed a 39% increase in hair count after 16 weeks compared to sham treatment. Results replicated in women.
Muscle Recovery
A meta-analysis of 39 studies in Lasers in Medical Science concluded that pre-exercise red light increases muscle endurance and post-exercise red light reduces soreness and damage markers.
Cellular Energy
Red light at 660nm and 850nm is absorbed by cytochrome c oxidase in the mitochondria — stimulating ATP production, the energy currency that powers every cell in your body.
Sleep Quality
A 2012 study of female basketball players found 14 days of red light exposure significantly improved sleep quality, melatonin production, and endurance performance vs placebo.
Pain Reduction
The Lancet published a 2009 systematic review showing low-level laser therapy provides effective short-term pain relief for chronic neck pain — with effects comparable to standard pharmacological treatment.
