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 Silk’n LED Face Mask 100 emits at 463 nm, 592 nm, 633 nm. The Silk’n LED Face Mask 100 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 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.
Questions
The Dr. Dennis Gross DRx SpectraLite FaceWare Pro emits at 415 nm, 630 nm. The Silk’n LED Face Mask 100 emits at 463 nm, 592 nm, 633 nm. The Silk’n LED Face Mask 100 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 Dr. Dennis Gross DRx SpectraLite FaceWare Pro carries more diodes: 162 against 100. 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. Silk’n LED Face Mask 100: CE marked cosmetic device — no FDA clearance for this model. 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.
