The short version
The Dr Dennis Gross DRx SpectraLite FaceWare Pro is one of the best-known LED face masks in the UK, sold in Sephora, Liberty and Harrods and created by a genuine New York dermatologist. It is also around £465. The Lumovex Spectrum Pro is £149.99. This is an honest look at what that £315 difference actually buys you, and where each mask genuinely wins.
Short answer: the Dr Dennis Gross wins on brand heritage, retail presence and a 3-minute session. The Lumovex Spectrum Pro wins on LED count, wavelength range and price. If you care most about a named-dermatologist brand on a department-store shelf, the FaceWare Pro makes sense. If you care most about the spec sheet and the price, the Spectrum Pro is hard to argue with.

Price: £465 versus £149.99
This is the headline. The Dr Dennis Gross FaceWare Pro sits at around £465 at RRP, occasionally discounted to about £418 at Liberty. The Lumovex Spectrum Pro is £149.99, roughly a third of the price.
Some of that gap is real. Dr Dennis Gross is a well-known dermatologist, the brand has a shelf in every major UK beauty hall, and that retail presence and reputation carry a premium. The question worth asking is whether the premium is buying you a better device, or a better-known one. On the hardware, as the next sections show, the case for the premium is thin.
LEDs and coverage
The FaceWare Pro uses 162 LEDs (100 red, 62 blue). The Lumovex Spectrum Pro uses 328 LEDs. More LEDs at the same wavelength generally means more even coverage across the face, so the Spectrum Pro puts roughly twice the light points across your skin.
Both masks are face-only. Neither extends over the neck as standard, so on coverage the two are level, and the difference comes down to how densely each one covers the face. Here the Spectrum Pro has the clear edge on paper.
Wavelengths: what you actually get
This is the part that matters most and gets talked about least.
The Dr Dennis Gross manual lists five wavelengths (blue, amber, red, deep red and infrared). However, independent irradiance testing published in 2026 reported that in real-world measurement the device functions effectively as a red (around 630nm) plus blue (415nm) mask, with the near-infrared reading as negligible. We would encourage you to read that testing for yourself and treat the five-spectrum figure as a manufacturer claim rather than a measured output.
Why does this matter? Near-infrared light (around 850nm) is the deeper-penetrating wavelength most associated in published research with collagen-depth work and recovery, rather than surface-level skin effects. A mask that does not deliver meaningful near-infrared is doing a narrower job than its spec sheet suggests.
The Lumovex Spectrum Pro runs four wavelengths - green 525nm, yellow 590nm, red 660nm and a genuine near-infrared 850nm. The red is also deeper (660nm versus 630nm). So on the wavelength that arguably matters most for anti-ageing depth, the cheaper mask is the one actually delivering it.
One note in Dr Dennis Gross's favour: the blue 415nm light is genuinely useful for blemish-prone skin, and it is a wavelength the Spectrum Pro does not run. If blue light for breakouts is your priority, that is a real point of difference. If your goal is anti-ageing and skin recovery, the near-infrared question is the more important one.
Fit, session length and durability
The FaceWare Pro's headline convenience feature is a 3-minute session, the shortest in this comparison. It is a rigid, hard-shell mask with an adjustable strap. Reviews are broadly positive on results but a recurring complaint is that the rigid shell can press uncomfortably on the bridge of the nose.
The more common durability concern in reviews is charging failure reported around the 18-month mark, which falls just outside the 1-year warranty. For a mask at this price, that is the criticism that stings most.
The Lumovex Spectrum Pro uses longer, more frequent sessions in the usual 10 to 15 minute range, 3 to 5 times a week, and is a softer-fit design. It carries a 1-year warranty, a 30-day return window, free UK mainland delivery and UK-based support.
Eye safety
Both masks are designed to be used without goggles, and the FaceWare Pro is FDA-cleared in the US. That said, the blue light in the Dr Dennis Gross device sits near the eyes, and blue-light-near-the-eyes is a live debate in reviews even where a device is cleared. If eye safety is on your mind, our honest guide on whether LED face masks are safe for your eyes walks through red, near-infrared and the specific blue-light caveat.
Where each mask wins
Dr Dennis Gross FaceWare Pro wins on: brand heritage (a real, well-known dermatologist), retail presence (Sephora, Liberty, Harrods), the shortest session at 3 minutes, and a dedicated blue-light mode for blemish-prone skin.
Lumovex Spectrum Pro wins on: LED count (328 versus 162), a wider four-wavelength range, a genuine near-infrared 850nm and deeper red 660nm, and price (£149.99 versus around £465).
So which should you buy?
Buy the Dr Dennis Gross FaceWare Pro if a named-dermatologist brand and a department-store presence give you the reassurance you want, if you value the 3-minute session, or if targeted blue light for breakouts is your main goal, and the price is not a concern.
Buy the Lumovex Spectrum Pro if you want the stronger spec sheet for the money: more than double the LEDs, a wider wavelength range, a genuine near-infrared for depth, and roughly a third of the price. The trade-off you accept is a newer brand with a smaller review base than a name that has been in Sephora for years, and we are honest about that.

What LED light therapy may help with
The published research most often cited around LED masks suggests they may help support visible signs of skin ageing, skin comfort and the appearance of redness, post-treatment skin recovery and general radiance over consistent use. Results vary by individual, and most people describe noticing changes around the 8 to 12 week mark with regular use.
LED masks are not designed to treat, diagnose or cure any medical condition. If you have a skin condition, photosensitivity, are pregnant, or take medication that increases light sensitivity, speak to your GP before starting a routine.
Frequently asked questions
Is there a cheaper alternative to the Dr Dennis Gross FaceWare Pro?
Yes. The FaceWare Pro is around £465 for 162 LEDs. The Lumovex Spectrum Pro is £149.99 with 328 LEDs and four wavelengths, including a genuine near-infrared 850nm that independent testing suggests the Dr Dennis Gross device does not deliver at a meaningful level. The trade-off is brand heritage and retail presence, where Dr Dennis Gross is stronger.
Does the Dr Dennis Gross mask have near-infrared light?
The manual lists an infrared wavelength, but independent irradiance testing in 2026 reported the near-infrared output as negligible in real-world measurement, with the device functioning effectively as a red plus blue mask. Near-infrared (around 850nm) is the deeper-penetrating wavelength most associated with collagen-depth and recovery, so this is worth checking if that is your goal.
How many LEDs does each mask have?
The Dr Dennis Gross FaceWare Pro has 162 LEDs (100 red, 62 blue). The Lumovex Spectrum Pro has 328 LEDs across four wavelengths. More LEDs generally means more even coverage across the face.
Which mask is better for anti-ageing?
For anti-ageing depth, the wavelength that matters most is near-infrared. The Lumovex Spectrum Pro delivers a genuine 850nm near-infrared plus a deeper red 660nm, while independent testing suggests the Dr Dennis Gross device is effectively red plus blue. For blemish-prone skin, the Dr Dennis Gross blue 415nm mode is a genuine point in its favour. Results vary by individual in both cases.
Is the Lumovex Spectrum Pro CE certified?
Yes. The Lumovex Spectrum Pro is CE certified. It comes with a 1-year warranty, a 30-day return window and free UK mainland shipping.
