A 2023 randomized controlled trial published in Photobiomodulation, Photomedicine, and Laser Surgery found that red light therapy at 660 nm reduced periocular wrinkle volume by up to 30% after just 10 treatment sessions.
Red light penetrates the dermis and stimulates fibroblasts to produce more collagen and elastin, leading to measurable improvements in skin texture, firmness, and fine lines.
Participants also reported significant improvements in skin hydration with no adverse side effects reported.
