- Wavelengths
- The Dr. Dennis Gross DRx SpectraLite FaceWare Pro emits at 415 nm, 630 nm. The Omnilux Contour Face emits at 633 nm, 830 nm. The Omnilux Contour Face 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 132. Diode count sets how evenly light reaches the face — a coverage figure, not an efficacy figure.
- Published irradiance
- Only the Omnilux Contour Face publishes an irradiance figure (~30 mW/cm²). The Dr. Dennis Gross DRx SpectraLite FaceWare Pro does not, so the dose the two masks deliver cannot be compared.
- 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 (rojo, azul o ambos). The Omnilux Contour Face runs 10 min (programa único, 3–5×/semana).
- Fit and power
- Dr. Dennis Gross DRx SpectraLite FaceWare Pro: carcasa rígida; controlador con cable. Omnilux Contour Face: silicona flexible; controlador recargable.
