Red Light Therapy (Photobiomodulation Panels)
Grade A — RCTs across skin collagen, joint pain, wound healing, and emerging cognition trials.
The evidence
Red (~660 nm) and near-infrared (~830 nm) LED therapy has the largest RCT base of any consumer longevity device. Meta-analyses support skin collagen synthesis, wound healing, and joint-pain reduction. Transcranial PBM trials (Saltmarche, Chao) show signals for mild cognitive impairment. Dose matters more than brand: irradiance (mW/cm²) and total dose (J/cm²) vary widely across consumer panels versus the trial protocols they reference.
Our picks
Mito Red Light MitoMAX
Higher irradiance per dollar than Joovv; smaller clinical citation footprint but third-party-measured specs published.

Kosher Evidence Card
- Halacha — Shabbat
- LED activation is hav'arah by most poskim; non-medical use is not permitted. Pre-set timers raise grama questions.
- Halacha — Yom Tov
- Same as Shabbat for elective cosmetic or joint-pain use.
- Choleh Status
- Most longevity / cosmetic use does not meet the choleh threshold. Documented post-injury rehab is a different conversation.
- Clinic Notes
- Home panels avoid all mixed-gender clinic considerations.
- Test Before Use
- Use eye protection at recommended irradiance; review any photosensitizing medications (e.g., doxycycline, isotretinoin).
- Ask Your Rav About
- Weekday-only protocols; skin coverage during sessions; whether grama (indirect) switching arrangements change the analysis.
FAQ
Do I need both 660 nm and 850 nm?
Most trials use one or both. 660 nm is better-studied for skin and surface tissue; 850 nm penetrates deeper for joints, muscle, and transcranial work. Dual-wavelength panels cover both.
How long should a session be?
Most consumer protocols target 10–20 minutes at 6–8 inches, 4–6 days per week. Total weekly dose matters more than per-session length.
