# Red Light Therapy Protocols by Goal (2026)

> Goal-matched photobiomodulation patterns for skin, hair, pain, and recovery—dose math first, gadgets second.

*Published 2026-07-10 · Updated 2026-07-10 · By Julian Hart*

*Medical disclaimer:* Not a device prescription. Eye safety and medical screening matter; discuss new therapies with a clinician when you have eye disease, photosensitizing drugs, or active cancer care.

The short answer

Match **goal → evidence grade → dose parameters** (wavelength band, irradiance, time, distance). Skin and hair have clearer consumer-device trails than metabolic miracle claims. See our [red light guide](https://healthcanon.com/light-and-recovery/red-light-therapy-complete-guide).

This roundup ranks protocol patterns by indication—not brands. Fluence without irradiance and time is incomplete math.

## Protocol lock

Every item assumes eye protection norms and manufacturer distance charts. More minutes is not automatically better.
