Dr. Dennis Gross DRx SpectraLite FaceWare Pro and Nanoleaf LED Light Therapy Face Mask, side by side. They share no listed wavelengths; Dr. Dennis Gross FaceWare Pro lists 160 LEDs and Nanoleaf Face Mask lists 432. Published specifications only; neither is ranked.
Near-infrared is the clearest difference: only the Nanoleaf Face Mask 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 5–10 min recommended. 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 Nanoleaf Face Mask lists 5 wavelengths and the Dr. Dennis Gross FaceWare Pro 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.
1 of the 15 summarised studies match both. 3 match only the Dr. Dennis Gross FaceWare Pro and 6 match only the Nanoleaf Face Mask.
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.
108 bulbs with four LEDs each. Manufacturer now lists output by mode and a 1–30 minute timer; recommended use is 5–10 minutes. Green is listed as 520 nm in one mode and 525 nm in blends. These update the older comparison snapshot. The 31 Oct 2026 page confirms 850 nm near-infrared in every colour mode and a 1–30 minute timer.
