Dr. Renú SpectraLift Advanced and The Light Salon Boost LED Face Mask (Boost Advanced), side by side. They share no listed wavelengths; Dr. Renú SpectraLift lists 280 LEDs and The Light Salon Boost lists 112. Published specifications only; neither is ranked.
Both list red and near-infrared light, the pairing used in several wrinkle studies.
Only the Dr. Renú SpectraLift lists blue light, which acne studies paired with red.
Sessions differ: 10–15 min versus 10 min. Session time alone does not set the dose; output matters too.
Six studies match both, including why red light may calm inflammation: the mechanism review.

LED count and output are not measures of effectiveness. Output figures use different, often unspecified measurement conditions. Prices keep their original currency and are not current offers.
The Dr. Renú SpectraLift lists 5 wavelengths and the The Light Salon Boost lists 2. More wavelengths is not the same as more effective.
No exact wavelengths in common, although some may sit in the same colour band.
6 of the 15 summarised studies match both. 4 match only the Dr. Renú SpectraLift and 0 match only the The Light Salon Boost.
Values shown are nominal wavelengths. The manufacturer page now gives approximate channel peaks of 630 nm red, 458 nm blue, 517 nm green and 850 nm near-infrared, nine modes, and 10–15 minutes, 3–4 times weekly. Earlier figures listed a 26.9–50.0 mW/cm² mode range.
Manufacturer specifications and price.
The manufacturer now sells this as the Boost LED Face Mask: 633 nm red + 830 nm near-infrared, 10-minute sessions, €450. LED Mask Specs lists it as Boost Advanced with 56 red and 56 near-infrared LEDs; the LED count was not found on the current page.
