Red Light Device Safety Basics: Eyes, Skin Sensitivity and Session Limits
Quick answer: Protect your eyes, check for light sensitivity, follow the session limits in your manual and stop if anything feels uncomfortable. When in doubt, ask your clinician before starting.
Home light devices are simple to use, but a few habits keep sessions safe. This is a general checklist and does not replace the manual for your device.
Safety checklist
| Area | Habit |
|---|---|
| Eyes | Close or shield your eyes and never stare at the light |
| Skin | Start with clean, dry skin and stop if it feels uncomfortable |
| Time | Use the timer and follow the manual |
| Heat | Stop if a device feels hotter than expected |
| Cables | Check cords and connectors before use |
Who should ask first
Talk to a clinician before using any light device if you are pregnant, have light sensitivity, use medications that affect light sensitivity or have a health question. Our safety and contraindications guide goes into more detail.
Using the AWA torch safely
The 3 in 1 torch is handheld, so keep the beam pointed away from eyes. See the eye protection guide.
