EU list prices checked 22 August 2026 on each maker’s own European storefront. List price only — sale prices are ignored, because they change weekly. Dose is irradiance × session length; it can only be calculated for the three makers that publish irradiance. Price per LED is arithmetic, not a quality measure: LED counts are not comparable between masks because individual LED power differs.
Evidence notes
The Dr. Renú SpectraLift™ Advanced uses 280 LEDs at 465 nm, 530 nm, 630–660 nm, 850 nm, in sessions of ~10 min.
Publishes an irradiance figure and states spectrometer testing. Its own efficacy testing is brand-run. The 465 nm blue and 530 nm green are less evidenced than the red and near-infrared.
The Nanoleaf LED Light Therapy Face Mask uses 432 LEDs at 640 nm, 850 nm, in sessions of 10–20 min.
FDA cleared with the second-highest diode count here, but 640/850 nm sit slightly off the most-studied 633/830 nm peaks, and the build is less substantial than the silicone masks.
The Shark CryoGlow (FW312) uses 160+ (multi-zone) LEDs at 415 nm, 630 nm, 830 nm, in sessions of 8 min.
Two disclosed brand-run 12-week studies — more published data than most rivals here. The under-eye cooling is a comfort feature, not a light mechanism.
The Silk’n LED Face Mask 100 uses 100 LEDs at 463 nm, 592 nm, 633 nm, in sessions of ~10 min.
A cosmetic device rather than a certified medical one. Its 463 nm and 592 nm are less evidence-backed than the core red and near-infrared.
The Therabody TheraFace Mask Glo uses 504 LEDs at 415 nm, 633 nm, 830 nm, in sessions of 12 min.
Cites a 104-subject study, the largest the brand claims in the category — brand-run. The vibration is a comfort extra, not a skin mechanism.
