Red and near-infrared light at specific wavelengths (630nm, 660nm, 850nm) penetrates skin up to 10mm deep, where it is absorbed by mitochondria — the cell’s energy powerhouses. This triggers increased production of ATP (cellular energy), which accelerates virtually every healing and regenerative process in the body: collagen synthesis, inflammation reduction, circulation improvement, and tissue repair. The benefits compound with frequency — the more consistently you use it, the more significant the effects.
