LED face masks · head to head

Dr. Dennis Gross DRx SpectraLite FaceWare Pro vs
Shark CryoGlow (FW312)

Two of the nine LED face masks in our comparison table, side by side. Every figure below is one the manufacturer publishes itself; where a brand stays silent the cell says so.

The short answer

The Dr. Dennis Gross DRx SpectraLite FaceWare Pro emits at 415 nm, 630 nm. The Shark CryoGlow (FW312) emits at 415 nm, 630 nm, 830 nm. The Shark CryoGlow (FW312) covers both red and near-infrared, the two ranges with the strongest published evidence for skin; the Dr. Dennis Gross DRx SpectraLite FaceWare Pro does not.

Neither brand publishes an irradiance figure, so the dose the two masks deliver cannot be compared from the specification sheets.

“Published irradiance” means the brand prints an output figure on its own product page. “FDA cleared” is not “FDA approved” — see the questions below.

Where they differ

Wavelengths
The Dr. Dennis Gross DRx SpectraLite FaceWare Pro emits at 415 nm, 630 nm. The Shark CryoGlow (FW312) emits at 415 nm, 630 nm, 830 nm. The Shark CryoGlow (FW312) covers both red and near-infrared, the two ranges with the strongest published evidence for skin; the Dr. Dennis Gross DRx SpectraLite FaceWare Pro does not.
LED count
The Dr. Dennis Gross DRx SpectraLite FaceWare Pro carries more diodes: 162 against 160. Diode count sets how evenly light reaches the face — a coverage figure, not an efficacy figure.
Published irradiance
Neither brand publishes an irradiance figure, so the dose the two masks deliver cannot be compared from the specification sheets.
Regulatory
Neither prints a searchable 510(k) number; both state their clearance without one. These devices are FDA cleared, not FDA approved — clearance is a safety and manufacturing signal, not proof of results.
Session and modes
The Dr. Dennis Gross DRx SpectraLite FaceWare Pro runs 3 min per session (red, blue or both). The Shark CryoGlow (FW312) runs 8 min (3 targeted programmes + under-eye cooling).
Fit and power
Dr. Dennis Gross DRx SpectraLite FaceWare Pro: rigid hard shell; corded controller. Shark CryoGlow (FW312): rigid, multi-zone; corded USB-C (cooling needs power).

Evidence notes

What the specifications don’t tell you

Dr. Dennis Gross DRx SpectraLite FaceWare Pro

The Dr. Dennis Gross DRx SpectraLite FaceWare Pro uses 162 (100 red · 60 blue) LEDs at 415 nm, 630 nm, in sessions of 3 min.

Pairs the best-evidenced anti-ageing (630 nm) and anti-acne (415 nm) wavelengths. No near-infrared. Evidence is brand-level.

Shark CryoGlow (FW312)

The Shark CryoGlow (FW312) uses 160+ (multi-zone) LEDs at 415 nm, 630 nm, 830 nm, in sessions of 8 min.

Two disclosed brand-run 12-week studies — more published data than most rivals here. The under-eye cooling is a comfort feature, not a light mechanism.

Questions

Common questions

What is the main specification difference between the Dr. Dennis Gross DRx SpectraLite FaceWare Pro and the Shark CryoGlow (FW312)?

The Dr. Dennis Gross DRx SpectraLite FaceWare Pro emits at 415 nm, 630 nm. The Shark CryoGlow (FW312) emits at 415 nm, 630 nm, 830 nm. The Shark CryoGlow (FW312) covers both red and near-infrared, the two ranges with the strongest published evidence for skin; the Dr. Dennis Gross DRx SpectraLite FaceWare Pro does not.

Neither brand publishes an irradiance figure, so the dose the two masks deliver cannot be compared from the specification sheets.

Which has more LEDs, the Dr. Dennis Gross DRx SpectraLite FaceWare Pro or the Shark CryoGlow (FW312)?

The Dr. Dennis Gross DRx SpectraLite FaceWare Pro carries more diodes: 162 against 160. Diode count sets how evenly light reaches the face — a coverage figure, not an efficacy figure.

Are the Dr. Dennis Gross DRx SpectraLite FaceWare Pro and the Shark CryoGlow (FW312) FDA cleared?

Dr. Dennis Gross DRx SpectraLite FaceWare Pro: FDA cleared 510(k) · CE. Shark CryoGlow (FW312): FDA cleared · CE/UKCA. Clearance under section 510(k) means the manufacturer showed substantial equivalence to a device already on the market and met safety standards — it is not FDA approval, and it is not evidence of efficacy.
