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 Dr. Dennis Gross DRx SpectraLite FaceWare Pro emits at 415 nm, 630 nm. The Nanoleaf LED Light Therapy Face Mask emits at 640 nm, 850 nm. The Nanoleaf LED Light Therapy Face Mask covers both red and near-infrared, the two ranges with the strongest published evidence for skin; the Dr. Dennis Gross DRx SpectraLite FaceWare Pro does not.
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 Dr. Dennis Gross DRx SpectraLite FaceWare Pro uses 162 (100 red · 60 blue) LEDs at 415 nm, 630 nm, in sessions of 3 min.
Pairs the best-evidenced anti-ageing (630 nm) and anti-acne (415 nm) wavelengths. No near-infrared. Evidence is brand-level.
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.
Questions
The Dr. Dennis Gross DRx SpectraLite FaceWare Pro emits at 415 nm, 630 nm. The Nanoleaf LED Light Therapy Face Mask emits at 640 nm, 850 nm. The Nanoleaf LED Light Therapy Face Mask covers both red and near-infrared, the two ranges with the strongest published evidence for skin; the Dr. Dennis Gross DRx SpectraLite FaceWare Pro does not.
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 162. Diode count sets how evenly light reaches the face — a coverage figure, not an efficacy figure.
Dr. Dennis Gross DRx SpectraLite FaceWare Pro: FDA cleared 510(k) · CE. Nanoleaf LED Light Therapy Face Mask: FDA cleared · CE. 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.
