Combined 633 nm and 830 nm light for wrinkles around the eyes

What they did

Thirty-one people received nine treatments with a clinic Omnilux LED system that combined 633 nm red and 830 nm near-infrared light. The doses were high by home-device standards: 126 J/cm² of red and 66 J/cm² of near-infrared.

Moulds of the skin around the eyes were scanned at weeks 9 and 12. Photos were assessed and participants rated their satisfaction.

What they found

Skin-surface measurements showed significant changes by week 12. About half of participants (52%) improved their photoageing score by 25–50%, and 81% said their eye-area wrinkles had improved noticeably.

What it cannot tell you

There was no control or sham group, so some improvement could come from expectation or seasonal skin changes. The doses came from a professional panel, not a consumer mask. The authors themselves called for further work on treatment settings.

In short

Encouraging but early evidence for the red-plus-near-infrared pairing that many masks now use. Treat it as a signal, not proof.

Matching a wavelength is not the same as matching the study. Dose, irradiance, session length and schedule also differ, and a mask’s reported output is not independently measured. See how dose works and home vs clinic doses.
