Dr. Dennis Gross DRx SpectraLite FaceWare Pro and Silk’n LED Face Mask 100, side by side. They share no listed wavelengths; Dr. Dennis Gross FaceWare Pro lists 160 LEDs and Silk’n Face Mask 100 lists 100. Published specifications only; neither is ranked.
Neither lists near-infrared, so both rely on visible light.
Both list blue light, which acne studies paired with red.
Sessions differ: 3 min versus 10 min; page also lists 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 Silk’n Face Mask 100 lists 3 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 0 match only the Silk’n Face Mask 100.
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 lists red 25.04, blue 89.68, yellow 13.23 and purple 77.95 mW/cm². Purple blends red and blue. This corrects the baseline’s missing-output label. Measurement conditions are not harmonised across brands.
