What The Research Shows
Red and near-infrared light therapy is one of the few wellness modalities with peer-reviewed clinical research behind it. Every claim below links to a published study.
Skin & Collagen
In a randomized controlled trial of 136 volunteers, red light treatment produced measurable improvements in skin roughness and increased intradermal collagen density — verified by ultrasound and blinded clinical photography.
Wunsch & Matuschka, 2014 →Muscle Recovery
A systematic review and meta-analysis of randomized controlled trials found photobiomodulation before exercise can improve muscular performance and reduce exercise-induced muscle fatigue in healthy people.
Vanin et al., 2018 →Joint Comfort
A meta-analysis of randomized controlled trials examining photobiomodulation for knee function, pain, and exercise tolerance in older adults reported measurable benefits across those outcomes.
Li et al., 2024 →Findings describe published research on red and near-infrared photobiomodulation as a modality. They are not claims about outcomes from any specific device. Ravlumi products are intended for general wellness use.
