Checked 31 October 2026 · Alphabetical order

What is different

Shared wavelengths: 630 nm
Only Dr. Dennis Gross FaceWare Pro: 415 nm
Only Dr. Renú SpectraLift: 465, 530, 660, 850 nm
LED count: 160 vs 280
Session: 3 min vs 10–15 min
Near-infrared: Only Dr. Renú SpectraLift lists near-infrared

Why it matters

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.

Dr. Dennis Gross DRx SpectraLite FaceWare Pro

Full specifications
Manufacturer source

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.
