Description
Mariana Bezerra Miranda and colleagues give a 2026 systematic review of LED light care for chronic leg wounds. Long lasting leg wounds heal slowly and return often, at high cost. LED photobiomodulation uses low light to nudge tissue repair, with no cuts and low cost. Proof from trials was mixed, so the team pooled randomized trials, the strongest trial type.
Six trials met the bar, with searches in four databases to May 2026. Light colours spanned red to near infrared, and doses spanned a wide range. Most trials hinted at gains: smaller wound area, better wound bed and more blood flow, most in diabetic foot ulcers. One trial at the highest dose showed no gain. Dose may have a sweet spot, so set dose rules are the next step.
