Two caveats sit alongside that: the clearance is held by the OEM and covers wrinkle reduction only, and in the EU the device is explicitly not CE-marked as a medical device.Fri, 18 Sep 2026 12:33:45 GMThttps://irradiancelab.com/devices/omnilux-contour-face/https://irradiancelab.com/devices/omnilux-contour-face/The most clinically cited consumer platform, running the best-evidenced 633/830 nm pairing. Publishes an irradiance figure, which most rivals do not.Fri, 18 Sep 2026 12:33:45 GMThttps://irradiancelab.com/devices/currentbody-skin-series-2/https://irradiancelab.com/devices/currentbody-skin-series-2/The official product page states UKCA registration and does not state FDA clearance — a point worth checking against how the device is marketed elsewhere. Stated weight of 1220 g appears to be packaged weight.Fri, 18 Sep 2026 12:33:45 GMThttps://irradiancelab.com/devices/therabody-theraface-mask/https://irradiancelab.com/devices/therabody-theraface-mask/Markets 648 LEDs as "3× more LEDs than the leading mask competitor". LED count is not dose: without irradiance, a higher count tells you nothing about delivered energy.Fri, 18 Sep 2026 12:33:45 GMThttps://irradiancelab.com/devices/shark-cryoglow/https://irradiancelab.com/devices/shark-cryoglow/The only mask here with a cooling function. Its FDA submission is the most technically detailed in the set, disclosing a full per-mode irradiance breakdown that appears nowhere in its consumer marketing.Fri, 18 Sep 2026 12:33:45 GMThttps://irradiancelab.com/devices/dr-dennis-gross-spectralite-faceware-pro/https://irradiancelab.com/devices/dr-dennis-gross-spectralite-faceware-pro/The only mask here running five wavelengths, and the only one whose advertised FDA clearance could not be traced to a public record. It publishes irradiance — but in the manual, not where buyers look.Fri, 18 Sep 2026 12:33:45 GMThttps://irradiancelab.com/conditions/wrinkles-and-collagen/https://irradiancelab.com/conditions/wrinkles-and-collagen/Red light at 633 nm and near-infrared at 830 nm produce small but measurable improvements in fine lines, skin texture and collagen density in controlled trials. Effects appear after 8–12 weeks of consistent use and are modest — visible in measurement, subtle in the mirror.Fri, 18 Sep 2026 12:33:45 GMThttps://irradiancelab.com/conditions/acne/https://irradiancelab.com/conditions/acne/Blue light near 415 nm is antibacterial against Cutibacterium acnes and reduces inflammatory lesions in controlled trials. The evidence is weaker than for topical or oral prescription treatment, and most consumer masks emit 460–470 nm rather than the 415 nm the trials used.Fri, 18 Sep 2026 12:33:45 GMThttps://irradiancelab.com/research/wunsch-matuschka-2014/https://irradiancelab.com/research/wunsch-matuschka-2014/Prospective, randomised, controlled, n=136.
