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. Renú SpectraLift™ Advanced emits at 465 nm, 530 nm, 630–660 nm, 850 nm. The Therabody TheraFace Mask Glo emits at 415 nm, 633 nm, 830 nm. Both cover red and near-infrared, the two ranges with the strongest published evidence for skin.
Only the Dr. Renú SpectraLift™ Advanced publishes an irradiance figure (up to 50 mW/cm²). The Therabody TheraFace Mask Glo 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. 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.
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. Renú SpectraLift™ Advanced emits at 465 nm, 530 nm, 630–660 nm, 850 nm. The Therabody TheraFace Mask Glo emits at 415 nm, 633 nm, 830 nm. Both cover red and near-infrared, the two ranges with the strongest published evidence for skin.
Only the Dr. Renú SpectraLift™ Advanced publishes an irradiance figure (up to 50 mW/cm²). The Therabody TheraFace Mask Glo does not, so the dose the two masks deliver cannot be compared.
The Therabody TheraFace Mask Glo carries more diodes: 504 against 280. Diode count sets how evenly light reaches the face — a coverage figure, not an efficacy figure.
Dr. Renú SpectraLift™ Advanced: FDA 510(k) K253712, Class II · CE · ISO 13485 · IEC 60601 · IEC 62471. 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.
