Science-backed red and near-infrared light therapy devices. What the research supports, which wavelengths work, and which panels are worth buying.
More red light therapy guides coming soon.
The two clinically supported wavelengths are 660nm (red light, penetrates skin surface) and 850nm (near-infrared, penetrates deeper tissue). Panels combining both wavelengths deliver the broadest range of benefits.
For face and skin: 6–12 inches. For deeper tissue benefits: 12–24 inches. Irradiance (mW/cm²) drops with distance, so closer is more potent. Most manufacturers specify dose at 6 inches.
10–20 minutes per session is the standard protocol for most body areas. Exceeding 20–30 minutes per area is not proven to add benefit and may cause transient redness.
Yes for most people. Avoid looking directly at the lights without eye protection. Not recommended during pregnancy or for people with photosensitive conditions or those taking photosensitizing medications.
