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 and launched to enormous consumer interest. At the time of writing, it has over 500 reviews on Boots alone with a 4.5-star average rating, making it one of the most reviewed LED face masks in the UK market. Available from Amazon, Boots, Argos, Currys, John Lewis, and Shark directly, it typically retails between £279.99 and £299.99.

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. The CryoGlow has disrupted the market by offering more technology for less money, and it is worth taking seriously.

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, so the metal cooling pads beneath your eyes feel genuinely cold against your skin.

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.

No other LED face mask currently available in the UK offers this feature. It is a genuine differentiator, not a marketing gimmick, and for anyone who deals with morning puffiness or dark circles, it adds real practical value to the daily 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’s clinical study with 59 subjects found that daily use produced more radiant, luminous skin in 4 weeks, with measurable improvements in fine lines and wrinkle reduction. The 630nm wavelength is well established in photobiomodulation research for stimulating fibroblast activity, which is the cellular mechanism behind collagen production.

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.

For those already taking bovine collagen supplements, combining oral supplementation with LED light therapy creates a complementary approach. The supplements provide the amino acid building blocks (glycine, proline, hydroxyproline) while the light therapy stimulates the cellular machinery to use them. We have covered this in more detail in our guide to red light therapy for collagen production.

The short answer: yes, the wavelengths used in the CryoGlow are scientifically relevant for collagen support. The clinical data showing improvements in fine lines within 4 weeks is consistent with what the broader research literature would predict. However, more significant collagen-related changes (skin firmness, elasticity, wrinkle depth) typically require 8 to 12 weeks of consistent use, which aligns with the CryoGlow’s 8-week programme structure.

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.

The CryoGlow wins on price, LED count, feature set, and review volume. 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.

For most UK buyers, the CryoGlow offers the best value. You get more LEDs, the unique cooling technology, blue light for acne (which neither competitor offers), shorter session times, and a remote control, all at a lower price point. 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. The shield design ensures even LED coverage across the face. 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.
