Red light (660nm) is absorbed near the surface — the skin and tissue right over the area. Near-infrared (850nm) is invisible to the eye and travels deeper, toward muscle and connective tissue. Photobiomodulation research has studied both wavelengths for decades; combining them covers the area at two depths in a single session.

Reviews are from verified purchasers. Individual experiences vary.
Use it every evening for two months. If it isn't part of your routine by then, send it back — we'll refund every cent, and we'll pay the return shipping. Plus a full 1-year warranty on the device itself.
Every RedGlow device runs the same 660nm + 850nm wavelengths — and every one includes the 60-night trial.
