The Science Behind Lifinity
Technology designed to support the way your body naturally produces energy, adapts and recovers.
Lifinity uses red light, near-infrared light and pulsed electromagnetic fields (PEMF) across selected devices. These technologies have been studied for their interaction with cellular signalling, mitochondrial activity and biological responses to physical energy.
No miracle claims. Just technology grounded in published science.
Red Light
660 nm Photobiomodulation
Your cells can respond to light. Red light at 660 nm sits within the wavelength range widely studied in photobiomodulation — the use of low-intensity light to influence biological processes.
Why it matters: a simple, non-invasive technology that can become part of a regular recovery, wellness or scalp-care routine.
Research reviews describe:
- Interaction between light and mitochondrial processes
- Changes in cellular energy-related signalling
- Modulation of nitric-oxide and redox pathways
- Biological responses that depend on wavelength, dose and treatment conditions

Near-Infrared
850 nm Near-Infrared Light
850 nm — light beyond what we can see. Near-infrared uses longer wavelengths than visible red light and has different optical characteristics within biological tissue.
Selected Lifinity BioFlex devices combine 660 nm red light with 850 nm near-infrared. The BioFlex Core Pro specification confirms both wavelengths.
Why it matters: near-infrared is commonly investigated where light needs to interact with tissue beyond the most superficial layers, making it particularly relevant to body-focused recovery and wellness applications.
Published photobiomodulation research describes red and near-infrared light as being capable of influencing mitochondrial activity, cellular redox signalling, tissue oxygenation-related responses and cellular signalling associated with energy metabolism. The response depends heavily on wavelength, intensity and total dose.
Neo Hair Revive does not contain near-infrared. It uses Red Light + PEMF only.

PEMF
Pulsed Electromagnetic Fields
Your body is not only chemical — it is also electrically active. PEMF devices produce changing electromagnetic fields. Researchers have studied how these fields may interact with electrically responsive biological processes, including cellular signalling and ion movement.
Why it matters: PEMF gives the body a different physical stimulus from light, allowing selected Lifinity products to combine photobiomodulation with electromagnetic technology in one wearable system.
A systematic review examining thousands of laboratory observations found that PEMF exposure can influence biological responses across different cell types. Outcomes depend strongly on:
- Frequency
- Field strength
- Exposure duration
- Cell type
- Treatment parameters
PEMF should never be treated as one generic technology. The parameters matter.

Red Light & Hair
One of the areas with human clinical research. Neo Hair Revive uses 660 nm red light + PEMF and does not contain near-infrared. Its technical specification lists 98 LEDs alongside the PEMF system.
A 24-week randomised, double-blind, sham-controlled multicentre trial reported that the active low-level light device produced a statistically significant improvement in hair-density measures compared with sham treatment in the studied population. A systematic review and meta-analysis of randomised trials also found that low-level light therapy produced greater improvements in hair-growth measures than sham devices across the studies included.
This research supports low-level light therapy as a technology category for pattern hair loss. It does not mean that every device produces identical results or that every user will respond in the same way.

Why Lifinity Combines Technologies
Different signals. One simple routine.
Red Light is photonic energy. Near-Infrared is longer-wavelength photonic energy used in selected BioFlex devices. PEMF is a pulsed electromagnetic stimulus. They do not work in exactly the same way.
Our approach is to combine complementary technologies where appropriate and make them simple enough to use consistently at home. The goal isn’t more technology. It’s useful technology that fits into your life.
Everyday Use
What Does That Mean for You?
Recover — create a regular recovery routine around training and demanding days.
Recharge — make time for your body rather than treating recovery as an afterthought.
Stay consistent — wearable technology makes short sessions easier to incorporate into normal life.
Think long term — use technology alongside the fundamentals of sleep, movement, nutrition and recovery.
The value isn’t one dramatic session. It’s making positive wellness habits easier to repeat.

Science without the hype
Our Science Standard
We believe you should know why a technology is inside your device. That’s why Lifinity focuses on published research, transparent specifications, realistic expectations and consistent use.
Research performed using another device does not guarantee identical outcomes with a Lifinity product, and individual responses vary.
The technologies we use are not chosen simply because they sound impressive. They’re chosen because there is real science worth exploring — shown on this page, beneath the relevant claims, without sending you away from the site.
