What is red light therapy and how does it work?

Red light therapy — formally known as photobiomodulation (PBM) — uses specific wavelengths of red and near-infrared light to stimulate cellular function. The light is absorbed by cytochrome c oxidase in the mitochondria, increasing ATP production, reducing oxidative stress, releasing nitric oxide, and modulating inflammation. Because mitochondria are present in virtually all cells, these effects are systemic — producing benefits across skin, muscle, joints, brain, and other tissue types.

What is the difference between red light (660nm) and near-infrared light (850nm)?

Red light at 660nm penetrates surface tissue and is primarily absorbed by skin cells, driving benefits like collagen stimulation, wound healing, and anti-inflammatory effects at the skin level. Near-infrared at 850nm is invisible and penetrates much deeper — reaching muscle, joints, tendons, and bone — making it the key wavelength for recovery, joint health, and deeper tissue regeneration. Joovv delivers both simultaneously for combined surface and deep tissue effects.

What makes Joovv medical-grade?

Joovv devices are independently tested and certified by Intertek to 8 IEC 60601 medical electrical equipment standards — the same framework applied to clinical medical devices. This includes standards for electrical safety, electromagnetic compliance, home healthcare environment use, photobiological safety, and risk management. Most consumer red light panels are not tested to these standards, regardless of marketing claims.

What benefits does red light therapy provide for athletes and biohackers?

For athletes, PBM accelerates recovery by reducing exercise-induced inflammation, clearing metabolic waste, and supporting muscle protein synthesis — reducing DOMS and improving return-to-training time. For longevity-focused biohackers, the key benefits are mitochondrial optimization, systemic anti-inflammatory effects, skin health and collagen support, sleep quality improvement (red light does not suppress melatonin), and emerging evidence for cognitive performance and brain health.

Who advises Joovv on the science?

Joovv's scientific advisory board includes Dr. Michael Hamblin (Principal Investigator at the Wellman Center for Photomedicine at Massachusetts General Hospital, Associate Professor at Harvard Medical School) and Dr. Cleber Ferraresi (physiotherapist, PhD in Biotechnology, Harvard/UFSCar). They bring over 500 combined peer-reviewed publications on photobiomodulation to Joovv's product development and protocol guidance.

How do I choose the right Joovv device?

Joovv offers a modular range from the portable Go 2.0 (targeted use, from $549) to full-body systems like the Solo 3.0 (from $1,699) and larger Elite/Max panels for complete front-and-back coverage. For most biohackers starting out, the Solo 3.0 provides sufficient coverage for full-body sessions. The modular design means panels can be combined and expanded over time. Joovv offers a buyer guide and product quiz on their website to help match device to goals.
