Dr. Dennis Gross DRx SpectraLite FaceWare Pro and Therabody TheraFace Mask Glo, side by side. They share 415 nm; Dr. Dennis Gross FaceWare Pro lists 160 LEDs and Therabody Mask Glo lists 504. Published specifications only; neither is ranked.
Near-infrared is the clearest difference: only the Therabody Mask Glo 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 12 min full routine. Session time alone does not set the dose; output matters too.
Four studies match both, including leds in dermatology: what 31 randomised trials add up to.

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 Therabody Mask Glo lists 3 wavelengths and the Dr. Dennis Gross FaceWare Pro lists 2. More wavelengths is not the same as more effective.
Yes: 415 nm.
4 of the 15 summarised studies match both. 0 match only the Dr. Dennis Gross FaceWare Pro and 6 match only the Therabody Mask Glo.
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.
Manufacturer confirms 504 LEDs, 415/633/830 nm and a 12-minute routine. Individual treatments run 4–12 minutes. Materials are PC/ABS and TPU; the original source’s semi-rigid description is replaced.
