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 The Light Salon Boost Advanced emits at 633 nm, 830 nm. The The Light Salon Boost 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 The Light Salon Boost Advanced publishes an irradiance figure (~30 mW/cm² · ~18 J/cm² per session). 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 The Light Salon Boost Advanced uses 112 (56 × 633 nm · 56 × 830 nm) LEDs at 633 nm, 830 nm, in sessions of 10 min.
Publishes both a per-session dose and a verifiable FDA clearance number — rare transparency for a consumer brand.
Questions
The Dr. Dennis Gross DRx SpectraLite FaceWare Pro emits at 415 nm, 630 nm. The The Light Salon Boost Advanced emits at 633 nm, 830 nm. The The Light Salon Boost 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 The Light Salon Boost Advanced publishes an irradiance figure (~30 mW/cm² · ~18 J/cm² per session). The Dr. Dennis Gross DRx SpectraLite FaceWare Pro does not, so the dose the two masks deliver cannot be compared.
The Dr. Dennis Gross DRx SpectraLite FaceWare Pro carries more diodes: 162 against 112. 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. The Light Salon Boost Advanced: FDA 510(k) K191629 · 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.
