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 Therabody TheraFace Mask Glo emits at 415 nm, 633 nm, 830 nm. The Therabody TheraFace Mask Glo 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 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.
Questions
The Dr. Dennis Gross DRx SpectraLite FaceWare Pro emits at 415 nm, 630 nm. The Therabody TheraFace Mask Glo emits at 415 nm, 633 nm, 830 nm. The Therabody TheraFace Mask Glo 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 Therabody TheraFace Mask Glo carries more diodes: 504 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. Therabody TheraFace Mask Glo: 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.
