Dr. Dennis Gross DRx SpectraLite FaceWare Pro and Dr. Renú SpectraLift Advanced, side by side. They share 630 nm; Dr. Dennis Gross FaceWare Pro lists 160 LEDs and Dr. Renú SpectraLift lists 280. Published specifications only; neither is ranked.
Near-infrared is the clearest difference: only the Dr. Renú SpectraLift lists it. Near-infrared (around 830–850 nm) appears in wrinkle and recovery studies, usually paired with red.
Both list blue light, which acne studies paired with red.
Sessions differ: 3 min versus 10–15 min. Session time alone does not set the dose; output matters too.
One studies match both, including red light and collagen density: a 136-person controlled trial.

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 Dr. Dennis Gross FaceWare Pro lists 2. More wavelengths is not the same as more effective.
Yes: 630 nm.
1 of the 15 summarised studies match both. 3 match only the Dr. Dennis Gross FaceWare Pro and 9 match only the Dr. Renú SpectraLift.
¹ Manufacturer lists 100 red + 60 blue lights, totalling 160, but the same page also says “up to 100 lights”. LED Mask Specs states 162. The page’s comparison table lists 630 nm red and 415 nm blue alongside 605 nm amber and 880 nm near-infrared, apparently across the brand’s device range; only red and blue are shown here.
Manufacturer LED breakdown/session; baseline wavelengths.
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.
