Your Guide to
Faster Recovery

Red and near-infrared light therapy has real research behind it for muscle recovery and skin — and a lot of marketing noise on top. This category cuts through it: the wavelengths that actually matter (660nm and 850nm), irradiance (power at the skin) that determines whether a panel does anything, treatment distance and time, and which panels, masks, and wraps deliver versus which are underpowered. We flag the specs manufacturers bury. Start with the roundups for the standouts at each size and budget, then read the reviews.
