Red Light Therapy Quick Reference Guide
A two-page plain-language reference for anyone considering red light therapy at home. The terms that matter, what the evidence actually supports for each use, who should pause and ask a physician first, with a checklist to work through before the first session.
Red light therapy has moved from the clinic to the living room faster than most people can keep up with. The marketing is confident, the device claims are broad, and very little of it tells you what the light is actually doing or where the evidence is valid. This guide is the short version every patient should read first.
It opens with the vocabulary: photobiomodulation, red versus near-infrared, irradiance, dose, biphasic response, and what FDA-cleared does and does not mean. Then a table setting out six common uses with an honest confidence rating for each, from acne, where home-use evidence is strongest, down to nasal and sinus symptoms, where it is preliminary and belongs alongside standard care rather than in place of it.
A do-and-do-not table follows, then, who should pause and ask first. Active cancer near the treatment area, pregnancy, thyroid uncertainty, photosensitizing medications, seizure disorders triggered by flicker, retinal disease. These are not rare, and a device that arrives at your door will not ask about any of them.
It closes with practical guidance on getting a fair trial — treating one goal at a time, tracking something objective rather than impressions, honoring the dose rather than assuming more is better, and thinking within a proper time frame. Also included: a seven-point checklist and a short list of symptoms that mean stop and seek advice.
Two pages. Print it and keep it with your device.
A companion Device & Protocol Guide covers device selection and starting protocols for each of my six selected uses.
