Red light therapy buying guide: 8 things to check
Use this checklist before you buy any at-home red light therapy device.
Talk to your doctor before you start, especially if you are pregnant, take photosensitizing medication, or have a skin or eye condition. See safety and contraindications.
1. Choose the type
Panel, pad, belt, hat, face mask or wand. Match it to the area you want to cover (see the table below). For the face, read mask vs wand.
2. Check the wavelengths
Brands usually list red (about 630–670 nm) and near-infrared (about 810–850 nm). Compare devices that list similar wavelengths.
3. Check the power figure, and how it was measured
Irradiance (mW/cm²) only means something with a measuring distance. Third-party measurements are more trustworthy than marketing figures.
4. Check the coverage area
A bigger panel covers more at once. A pad covers one spot. Make sure the size suits what you want.
5. Look for a timer and auto shut-off
It helps you stick to the maker's recommended session length.
6. Eye protection
Panels and face-height devices should come with goggles. Never look straight into the lights.
7. Warranty, return window and shipping
A long return window lets you try it at home. Check it ships to your country and lists the right electrical safety marks.
8. Talk to your doctor
Especially if you're pregnant, take photosensitizing medication, have a skin or eye condition, or have an implanted device.
