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 The Light Salon Boost Advanced emits at 633 nm, 830 nm. Both cover red and near-infrared, the two ranges with the strongest published evidence for skin.
Both publish an output figure: the Dr. Renú SpectraLift™ Advanced states up to 50 mW/cm², the The Light Salon Boost Advanced states ~30 mW/cm² · ~18 J/cm² per session. Only three of the nine masks this site compares publish one at all.

“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 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. Renú SpectraLift™ Advanced emits at 465 nm, 530 nm, 630–660 nm, 850 nm. The The Light Salon Boost Advanced emits at 633 nm, 830 nm. Both cover red and near-infrared, the two ranges with the strongest published evidence for skin.
Both publish an output figure: the Dr. Renú SpectraLift™ Advanced states up to 50 mW/cm², the The Light Salon Boost Advanced states ~30 mW/cm² · ~18 J/cm² per session. Only three of the nine masks this site compares publish one at all.
The Dr. Renú SpectraLift™ Advanced carries more diodes: 280 against 112. 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. 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.
