The light, the devices and the research.
Made simpler to understand.
Why red light?
Researchers study red and near-infrared light in skin, scalp and post-exercise routines. The findings depend on the device and protocol tested, and do not establish results for every home-use device.
What it is
Red light therapy delivers red and/or near-infrared light to the skin. Researchers study how absorbed light may change cell activity — a process called photobiomodulation. See how it works
The science, made visual
Red light & near-infrared, explained.
Light-sensitive molecules in cells can absorb certain wavelengths. Researchers are investigating how this may affect mitochondria — the cell’s energy-producing structures — and cellular signalling. These mechanisms do not by themselves establish a product benefit.
- Red light — skin & scalp
Visible red light is studied for skin appearance and its interactions with hair follicles. Some studies report cosmetic improvements, but their findings apply to the tested devices and protocols rather than every red-light product.
- Near-infrared — deeper tissue & recovery
Invisible near-infrared light generally travels further into tissue than visible red light. Research explores its possible role in post-exercise recovery; this does not establish a soreness or recovery benefit for the devices sold here.
- Follow the device instructions
Distance, session length and frequency affect light exposure. Follow the instructions for your particular device; longer or brighter sessions should not be assumed to work better.
Find your setup
Different devices.
A routine that fits you.
Choose the coverage you need and a setup you can use regularly. Wearables hold the light close to one area; panels and lamps let you position it around different areas of the body.
Choose your area
Masks cover the face, caps and scalp wraps target the scalp, and body wraps fit around selected areas. Choose a panel or lamp for a freestanding device you can reposition.
Check the details
Compare wavelengths, coverage and recommended distance on the product page. Then check the practical details: straps and fit, power supply, and the space you need to use it comfortably.
Build your routine
Choose a regular slot — while reading, winding down or after exercise. Follow your device’s session time and frequency, and make the setup easy enough to repeat.

The research on pattern hair loss
This review found benefits from red light in studies of pattern hair loss. Different causes of hair loss and different devices should not be assumed to respond in the same way.

Light & post-exercise recovery
A review of 14 studies found reduced muscle soreness and improved recovery of strength at some time points after exercise. Four studies contributed to the pooled analysis; treatment protocols varied.
