Photonic / Light
Photobiomodulation / LLLT — Low-Level Light Therapy Evidence-supported · Evidence-supported
Specific FDA-cleared uses (e.g., oral mucositis, certain pain / wound indications).
Off-label · Insufficient-evidence
Broad / systemic 'all-light-heals', cognitive, anti-aging claims.
Real photomedicine: red/NIR light on cytochrome-c-oxidase, with FDA-cleared specific uses; broad/systemic claims remain frontier. Distinct from methylene blue, which is redox pharmacology, not photobiomodulation.
Origin & lineage
Mainstream photomedicine.
Claimed mechanism
Red / NIR light (600–1000 nm) → cytochrome-c-oxidase → ATP↑, ROS↓.
Plausibility
Plausible, grounded — real photoacceptor; biphasic dose and wavelength / penetration matter.
Evidence — grade B
Mechanism solid; ~12 systematic reviews 2019–23 mostly positive; GRADE low; strongest in oral mucositis.
Market
Makers: Joovv; Vielight; Erchonia; THOR; LiteCure.Models: Joovv panels; Vielight; Erchonia (510(k)s).Price: Consumer panels $500–2K; clinical $2–20K+.
Kernel — keep vs set aside Keep — real substrate
Real photoacceptor (cytochrome-c-oxidase); dose, wavelength and penetration are real, quantifiable levers.
Set aside — claim
'All frequencies heal' / broad systemic / anti-aging generalization is unsupported.
Regulatory status by jurisdiction Registration or clearance is a market-access fact, never proof of efficacy.
US — FDA FDA-cleared specific uses; consumer panels unregulated for disease. EU — MDR CE varies. Russia Not specified in source. China — NMPA Not specified in source. Australia — TGA Not specified in source.

It reports the mechanism, evidence grade, and regulatory status of physical and energy-based modalities, including the views and claims of third parties, with sources cited where they exist. Regulatory registration or clearance is a market-access fact, never proof of efficacy. Nothing here is an endorsement, a diagnosis, or a treatment recommendation.
