2025 · Randomised, sham-controlled, double-blind trialTwo sessions or three? A red-mask trial
Two weekly sessions did as well as three in this trial. Specialist photo scores did not show a difference from sham.
2023 · Randomised split-face trialRed or amber light for eye-area wrinkles?
The two colours gave similar wrinkle changes. Neither changed hydration or elasticity in this study.
2020 · Prospective controlled studyDoes a home mask add to a serum routine?
The mask group improved more, but this short study had no sham mask and included authors linked to a mask maker.
2020 · Randomised animal studyRed and near-infrared light on skin grafts in rats
Red light did more in this particular animal model. That does not establish the better wavelength for human skin.
