In This Review
Which Shark CryoGlow mask should UK buyers choose in 2026?
Important model distinction (checked 5 November 2026): This review covers the original CryoGlow FW312UK, not the newer Plus or Clinic. Shark now sells three different face-mask versions. Prices below are Shark UK’s advertised prices at the time of checking, not guaranteed checkout prices.
| Face mask | Shark UK price checked | Main difference |
|---|---|---|
| Original CryoGlow (FW312UK) | £239.99 sale (usually £299.99) | Four LED/cooling routines; three under-eye cooling levels. |
| CryoGlow Plus (FW350UK) | £339.99 | Shark claims wider LED coverage around the eyes and mouth, plus improved battery performance. |
| CryoGlow Clinic Face (FW425UK) | £379.99 | Under-eye heating and cooling, with additional customisable routines. |
Buying verdict: If adjustable cooling and the original LED routines meet your needs, the discounted FW312UK is the lower-cost choice. Consider Plus if extra coverage matters, or Clinic Face for hot-and-cold under-eye therapy. These are manufacturer feature comparisons, not our own head-to-head tests. See our wider UK LED face-mask comparison.
What Is the Shark CryoGlow?
The Shark CryoGlow is an at-home LED light therapy face mask made by Shark Beauty, the skincare arm of SharkNinja, the company behind Shark vacuum cleaners and Ninja kitchen appliances. If that sounds like an unusual pedigree for a skincare device, you are not alone in thinking that. But Shark has done something genuinely interesting here.
The CryoGlow is the UK’s first LED face mask to integrate under-eye cooling technology directly into the device. While other masks focus exclusively on light therapy, the CryoGlow combines 480 LEDs across three clinically relevant wavelengths with InstaChill Cold Technology: two active cooling points that sit beneath your eyes and help soothe, depuff, and tighten the under-eye area during treatment.
It was developed with dermatologists. Instead of relying on a fixed review count across retailer listings, compare recent customer feedback for the exact FW312UK model. Available from Amazon, Boots, Argos, Currys, John Lewis, and Shark directly, Shark’s website showed £239.99, reduced from £299.99, on 5 November 2026; prices, colours and stock can change.
For context, the CurrentBody Series 2 LED Mask costs significantly more, and the Omnilux Contour Face sits at a similar price point but without the cooling feature. Its under-eye cooling is a distinctive extra, but the right choice depends on fit, treatment modes and current price rather than LED count alone.
The Under-Eye Cooling Technology
This is the CryoGlow’s standout feature and the reason it has generated so much buzz. The InstaChill Cold Technology uses the Peltier effect, where electrical current passes through two different materials to create a temperature differential. One side gets cool, the other gets warm. Shark combines this with fan technology to expel the excess heat outward, and Shark says the metal under-eye pads deliver adjustable cooling during use. We have not tested how cold they feel.
There are three adjustable chill levels, and you can use the cooling feature independently (via Under-Eye Revive mode for 3 to 15 minutes) or combine it with any of the LED treatment modes. The cooling is controlled via the included remote control, which clips to your clothing for hands-free operation.
Why does under-eye cooling matter? Cold therapy causes blood vessels to constrict, which reduces puffiness and can temporarily tighten the skin. If you have ever held a cold spoon or ice cube under your eyes in the morning, you know the effect. The CryoGlow delivers this consistently and at a controlled temperature, rather than leaving you fumbling with melting ice.
Under-eye cooling remains the defining feature of the original CryoGlow, although Shark also offers it on the newer Plus and Clinic Face variants. How useful it is depends on whether you want temporary cooling alongside an LED routine.
The 4 Treatment Modes Explained
The CryoGlow offers four pre-programmed treatment modes, each combining different LED wavelengths for different skin goals. All can be paired with the under-eye cooling.
1. Better Ageing Mode (6 minutes)
Uses red LEDs (630nm) combined with deep infrared (830nm). This is the anti-ageing mode, targeting fine lines, wrinkles, and skin firmness. Shark cites an eight-week manufacturer study of 59 participants using its six-minute Better Ageing routine daily, reporting changes in the appearance of fine lines; results may vary and should not be treated as guaranteed. The 630nm wavelength is well established in photobiomodulation research for stimulating fibroblast activity, which is the cellular mechanism behind collagen-related mechanisms.
2. Blemish Repair Mode (8 minutes)
Combines blue LEDs (415nm) with red (630nm) and deep infrared (830nm). Blue light at 415nm targets the bacteria that contribute to acne breakouts, while the red and infrared wavelengths support healing and reduce inflammation. A separate clinical study with 60 subjects showed improved blemishes and reduced skin roughness within 4 weeks of daily use.
3. Skin Sustain Mode (4 minutes)
A maintenance mode that combines blue, red, and infrared LEDs in a shorter session. Designed to maintain results after completing an 8-week cycle of Better Ageing or Blemish Repair mode. Think of this as your upkeep routine once you have achieved the initial results.
4. Under-Eye Revive Mode (3-15 minutes)
Cooling only, no LEDs. Adjustable session length from 3 to 15 minutes with three temperature settings. This is for mornings when you want to depuff and refresh your under-eye area quickly without a full LED session. Useful as a standalone treatment or before applying makeup.
Does It Actually Boost Collagen?
This is BovineCollagen.co.uk, so let us address the collagen question directly.
The CryoGlow’s Better Ageing mode uses red light at 630nm and deep infrared at 830nm. Both wavelengths fall within the range that peer-reviewed research has shown to stimulate fibroblast activity and support collagen synthesis in human skin. A 2014 study published in Photomedicine and Laser Surgery found that participants using red and near-infrared light therapy saw significant improvements in skin complexion and collagen density.
The mechanism is well understood: red light at these wavelengths penetrates the dermis and interacts with cytochrome c oxidase in the mitochondria, boosting cellular energy production (ATP). This increased energy availability supports the fibroblasts, the cells responsible for producing collagen and elastin, to work more effectively.
There is insufficient evidence to claim this mask will deliver a particular collagen increase, and a change in skin appearance should not be treated as proof of one. Choose a face mask based on the intended use, eye-safety instructions, comfort, return policy and evidence for that specific model.
The short answer: research on red and near-infrared light is promising for some cosmetic skin outcomes, but the evidence for this exact device is more limited. Shark’s eight-week Better Ageing study reports changes in the appearance of fine lines, but manufacturer results should not be interpreted as guaranteed outcomes. The product’s stated routines and manufacturer study duration do not establish a universal timeline for collagen production.
Shark CryoGlow vs CurrentBody vs Omnilux
These are the three LED face masks most UK buyers are choosing between. Here is how they compare on the specs that actually matter.

| Price | £239.99 Shark UK sale (5 Nov 2026) | Check live price | Check live price |
| LEDs | 480 | 236 | 132 |
| Wavelengths | 630nm, 415nm, 830nm | 633nm, 830nm, 1072nm | 633nm, 830nm |

The CryoGlow stands out for under-eye cooling, red/blue/infrared treatment modes and short sessions. Do not assume that more LEDs automatically make a mask more effective, and compare live prices before choosing. The CurrentBody Series 2 wins on wavelength breadth with the addition of 1072nm deep near-infrared, which penetrates deeper into tissue. The Omnilux has the longest track record and strong brand reputation in the clinical aesthetics space.
The CryoGlow is worth considering if under-eye cooling and short treatment routines matter to you. You get more LEDs, the unique cooling technology, blue light for acne (which neither competitor offers), shorter session times, and a remote control, but pricing varies by retailer and promotions. The CurrentBody Series 2 is the better choice if you specifically want the deepest possible near-infrared penetration (1072nm) and do not care about cooling or blue light. We have a full CurrentBody Series 2 review and an Omnilux vs CurrentBody comparison if you want to dig deeper into those options.
If your primary concern is collagen production specifically, the CryoGlow and CurrentBody are both strong choices. If you want to address acne alongside anti-ageing, the CryoGlow is the only mask of the three that includes blue light therapy.
Design, Fit & Usability
The CryoGlow is designed for a universal fit with forehead and temple padding, adjustable straps, and silicone eye shields for LED light blocking and comfort. Shark says the eye shields are designed to help protect the eyes; comfort and fit will vary. It is not the sleekest looking mask on the market, but it is functional and comfortable enough for daily use.
The remote control is a genuinely useful inclusion. It features an LCD screen that lets you select modes, adjust cooling levels, pause or end routines, and track your session history. It clips to your clothing with a belt clip, leaving your hands free during treatment. After each session, the remote displays your total sessions completed in that routine, and when you return it reminds you where you left off. This session tracking is a small but clever touch that helps with consistency.
Charging is via USB-C, which is convenient and universal. The mask comes with an LED protective cover for storage that also keeps the remote control and chill pads secure.
One practical consideration: the cooling pads need to be clean and the mask needs to sit flush against your face for the cooling to work properly. Begin each session with a clean, dry face for best results. Apply skincare products after your treatment, not before, as they can interfere with both the LED light delivery and the cooling contact.

Our Verdict
The Shark CryoGlow has earned its spot as one of the best LED face masks in the UK. Its 480 LEDs, three stated wavelengths and integrated under-eye cooling make it distinctive, although the best value depends on current retailer prices and your intended use.
The cooling system is a differentiator if under-eye puffiness is a priority, although the newer Shark Plus and Clinic models also include cooling features. The blue light mode for blemish repair is another meaningful advantage over CurrentBody and Omnilux, whose Series 2 and Contour Face models focus on red/near-infrared wavelengths.
When choosing between LED masks, prioritise a comfortable fit, realistic treatment time, eye protection, warranty and return terms rather than assuming that more LEDs automatically mean better results. For an alternative with a different light configuration, see our CurrentBody Series 2 mask review.
Shark’s UK guarantee extends to two years for eligible registered devices; purchases direct from Shark are normally registered automatically, while third-party purchasers should register within 28 days. Keep your proof of purchase and read the applicable terms.
If you want an LED face mask with a blue-light routine and under-eye cooling, the original CryoGlow is worth comparing against newer Shark models and other masks at their current prices.

The UK’s first LED face mask with under-eye cooling
- 480 LEDs across red, blue, and deep infrared wavelengths
- InstaChill under-eye cooling with 3 temperature levels
- Shark cites an eight-week fine-line study and four-week blemish study
- Compare current buyer reviews for FW312UK, not the newer Shark masks
