LED face masks · head to head
Two of the nine LED face masks in our comparison table, side by side. Every figure below is one the manufacturer publishes itself; where a brand stays silent the cell says so.
The short answer
The Nanoleaf LED Light Therapy Face Mask emits at 640 nm, 850 nm. The Shark CryoGlow (FW312) emits at 415 nm, 630 nm, 830 nm. Both cover red and near-infrared, the two ranges with the strongest published evidence for skin.
Neither brand publishes an irradiance figure, so the dose the two masks deliver cannot be compared from the specification sheets.

“Published irradiance” means the brand prints an output figure on its own product page. “FDA cleared” is not “FDA approved” — see the questions below.
Where they differ
Evidence notes
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.
Questions
The Nanoleaf LED Light Therapy Face Mask emits at 640 nm, 850 nm. The Shark CryoGlow (FW312) emits at 415 nm, 630 nm, 830 nm. Both cover red and near-infrared, the two ranges with the strongest published evidence for skin.
Neither brand publishes an irradiance figure, so the dose the two masks deliver cannot be compared from the specification sheets.
The Nanoleaf LED Light Therapy Face Mask carries more diodes: 432 against 160. Diode count sets how evenly light reaches the face — a coverage figure, not an efficacy figure.
Nanoleaf LED Light Therapy Face Mask: FDA cleared · CE. Shark CryoGlow (FW312): FDA cleared · CE/UKCA. Clearance under section 510(k) means the manufacturer showed substantial equivalence to a device already on the market and met safety standards — it is not FDA approval, and it is not evidence of efficacy.
