Only Shark CryoGlow lists near-infrared
Why it matters
Near-infrared is the clearest difference: only the Shark CryoGlow 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 6.4 min ageing · 8.4 min clearing · 4.3 min maintenance. Session time alone does not set the dose; output matters too.

Questions
Which has more wavelengths, the Dr. Dennis Gross FaceWare Pro or the Shark CryoGlow?
The Shark CryoGlow lists 3 wavelengths and the Dr. Dennis Gross FaceWare Pro lists 2. More wavelengths is not the same as more effective.
Do the Dr. Dennis Gross FaceWare Pro and Shark CryoGlow share any wavelengths?
Yes: 415, 630 nm.
Which research matches each mask?
4 of the 15 summarised studies match both. 0 match only the Dr. Dennis Gross FaceWare Pro and 6 match only the Shark CryoGlow.
Manufacturer page checked 2 November 2026 lists 100 red and 60 blue lights, but also says up to 100 lights. It describes red, blue and combined modes with a three-minute automatic shut-off. Its comparison table additionally lists 605 and 880 nm in the FaceWare column; the exact spectral configuration is unresolved, so the wavelength array keeps only the shared red/blue values. K183247 is a possible family match, not a confirmed retail-model match.
