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 Dr. Renú SpectraLift™ Advanced emits at 465 nm, 530 nm, 630–660 nm, 850 nm. The Dr. Renú SpectraLift™ Advanced 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.
Only the Dr. Renú SpectraLift™ Advanced publishes an irradiance figure (up to 50 mW/cm²). The Dr. Dennis Gross DRx SpectraLite FaceWare Pro does not, so the dose the two masks deliver cannot be compared.

“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 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.
Questions
The Dr. Dennis Gross DRx SpectraLite FaceWare Pro emits at 415 nm, 630 nm. The Dr. Renú SpectraLift™ Advanced emits at 465 nm, 530 nm, 630–660 nm, 850 nm. The Dr. Renú SpectraLift™ Advanced 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.
Only the Dr. Renú SpectraLift™ Advanced publishes an irradiance figure (up to 50 mW/cm²). The Dr. Dennis Gross DRx SpectraLite FaceWare Pro does not, so the dose the two masks deliver cannot be compared.
The Dr. Renú SpectraLift™ Advanced carries more diodes: 280 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. Dr. Renú SpectraLift™ Advanced: FDA 510(k) K253712, Class II · CE · ISO 13485 · IEC 60601 · IEC 62471. 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.
