Shark Cryoglow: One minute review
Whether you have fine lines, rosacea, acne or puffy under-eyes, Shark’s CryoGlow can address a wide range of skincare concerns. It combines LED face mask technology with Peltier-effect cooling pads that could replace your weekly trips to the salon.
CryoGlow is my first foray into light therapy technology. While I’m eager to see further studies into the long-term benefits (and potential risks), I must say, I’ve been impressed with Shark’s first skincare device.
Of course, it’s not fully effortless. I spent over seven hours strapped into the CryoGlow in my two months of testing, using one of its three settings almost every night to put it through its paces.
It’s not been without its drawbacks. I travel a fair amount, spending half my time at my partner’s home and half at mine, plus going on press trips, and, unfortunately, CryoGlow is bulky and inflexible. The device isn’t built for effective packing, and can’t be put in a checked bag owing to its lithium-ion battery. Battery life might prove to be irritating, too, especially over time and if you’re following the advised daily-use routine.
That being said, it’s still a whole lot more convenient and cost-effective in the long run than weekly trips to your salon to receive the same treatment. If, like me, you’re a regular under-eye mask wearer, this is a much more sustainable way to minimize your puffy eyes.
The biggest question, of course, is whether or not CryoGlow delivers results. For me, the answer is a tentative yes; after over two months of consistent testing, my acne has noticeably reduced outside of hormonal outbreaks, my fine lines seem reduced and, in defiance of my terrible sleep schedule, my under-eye puffiness has lessened. Best of all, the routine of it all encourages me to moisturize daily (the mask itself is quite drying) and means I have to use fewer pimple patches and eye masks.
Is it the sea-change I was hoping for? No, and the results aren’t long-lasting unless you continue to regularly use the mask after the initial eight-week regimen. Still, I’m pretty impressed with what I’ve seen, and it’s the best alternative I’ve found to regular, professional skincare treatments.
Shark Cryoglow review: Price and availability
- Announced and released in late 2024
- Costs $349 / £299
- Comfortably mid-range among LED face masks, plus with added benefits.
The Shark CryoGlow is available for $349 / £299 (as of writing, it’s not available in Australia) and can be purchased directly from Shark as well as a number of third-party retailers such as Amazon. In the UK, that marks a small increase in price in the few months since its launch, when it cost £249.
Out of the box, the CryoGlow comes with a travel bag, an extra set of InstaChill Peltier-effect plates and the mask itself with the attached remote. You can also buy a charging stand for the mask for $49.99 / £49.99, which gives the mask a tidy home.
In terms of value for money, the CryoGlow may be pricey, but it stands to benefit your beauty budget in the long run. Its biggest competition in home treatment comes from the likes of Currentbody, which costs $469 / £399 for its latest Series 2 model. While regular salon treatments can range from $25-200 / £25-200 each trip, which adds up quickly if you want to sustain the results.
Shark Cryoglow review: Design
- Solid and inflexible mask
- Attached remote
- Features Peltier-effect under-eye cooling plates
Unlike many of its competitors, Shark’s CryoGlow is a rigid, hard-shelled light therapy mask with added cushioning for comfort around the eyes and on the forehead. While it’s a little heavy and inflexible (675g) for my liking when it comes to travel, it’s still pretty comfortable in use, owing to the adjustable straps across the top and sides of the head that spread the mask’s weight, and its holes for the eyes, mouth and nose.
While these cutouts are sufficiently comfortable, I’d argue against using this mask while doing anything other than relaxing or maybe some light doomscrolling. The eye cushions adequately block out most of the light from behind the mask, but I found that after a few weeks of testing, I started to suffer eye strain and headaches, which I attributed to using screens in a dimly lit room while wearing the CryoGlow every evening. The contrast between the LED light bleeding into my periphery against the light on my TV or phone didn’t quite agree with my eyes, it seems. For wellness’ sake, I suppose it’s better to treat your skin routine more meditatively.
The remote is wired into the mask itself and features a small LCD screen, which lets you track and select your skincare routines and the time remaining during a treatment, and a dial for selecting options. The mask charges via a USB-C connector in the remote.
Under the hood, CryoGlow features 160 tri-wick LEDs, which translates to 480 light sources across the three light therapy programs (red, blue, and deep infrared light). Beneath the eye holes are the InstaChill cooling pads, which use the Peltier effect, a thermoelectric phenomenon that creates a cooling effect on the skin side of the cooling pads when powered, and fan technology to deliver under-eye bag-busting cooling. Clever stuff. By default, the mask features just one set of these cooling pads, but if you find it more comfortable, you can add the included second pair to bring the cooling closer to your face.
It’s worth highlighting that a vast majority of competitor products feature a more flexible form factor, which may be more accommodating for different face shapes and sizes. However, from what I’ve found so far in my own testing, consumer reviews and the opinions of my friends and family who’ve tried Shark’s mask, the hard shell, one-size-fits-all approach seems to be fairly universal. Plus, you benefit from the under-mask fans, which keep everything cool and refreshing in use.
Shark Cryoglow review: Performance
- Various treatments for different skin needs
- Three controllable coolness settings for the under-eye
- Battery life unimpressive
How it works
Shark’s CryoGlow has three light therapy routines that address different skincare goals: Better Aging, Blemish Repair and Skin Sustain Treatment. Each mode uses different LEDs to penetrate the skin.
Better Aging uses Red LEDs and Infrared over a six-minute cycle to reduce fine lines and firm skin, with a recommended eight-week course.
Blemish Repair adds Blue LEDs to the mix across an eight-minute routine to reduce blemishes, smooth skin and improve the appearance of pores after a four-week course.
Once you’ve completed a full treatment cycle, Skin Sustain combines all three light treatments into one, four-minute cycle designed to maintain the results.
Using the remote, you can add under-eye cooling with one of three intensity settings, or use the fourth treatment option, Under-Eye Revive, to de-puff your eyes for up to 15 minutes without LEDs.
I tried the Blemish Repair and Better Aging treatments in my time with the mask, starting with Blemish Repair for the full four weeks. Though my quest for a fully effective, adult acne-blasting solution continues, I did at least notice a reduction in my symptoms. With consistent, daily use, my pimples reduced in size, severity and redness. I have very large pores that were at least somewhat tightened and smoothed by the treatment, and, overall, my acne was quicker to heal, drying out much more readily than I’m used to.
For me, that’s worth it; I have found few solutions that are at all effective in making my acne easier to live with. However, it’s still a big investment for moderate results, and I can only anecdotally say it had a slightly noticeable effect on my skin. I’ll be using CryoGlow for as long as I can to see if the improvements continue, but as the search for my acne’s silver bullet continues, so might yours.
Following Blemish Repair mode, I took a two-week break to test how lasting the results are, and found my skin slowly returning to form towards the end of the break, when I picked up the mask once more to try Better Aging mode. As of writing, I’m just over halfway through the treatment, and I’ve seen some positive early results when it comes to fine line reduction – however, it’s worth noting these aren’t (yet!) too much of a problem for me. That being said, I do struggle with skin puffiness, especially when I’m run down, and the red light therapy proved effective in soothing my inflammation.
For me, easily the most effective part has been the InstaChill under-eye cooling. No longer do my puffy eyelids and under-eye bags betray my terrible sleep schedule, thanks to daily cooling treatments that leave me feeling refreshed and relaxed. I’ve been using single-use eye masks for a few months, and CryoGlow is both more effective and less wasteful; a double-whammy of cosmetic coolness.
The cycles of all of the CryoGlow treatments are relatively short, meaning it doesn’t feel too large of a commitment, but the short battery life only sees three or four treatments through, and if you’re regularly on the move you might find toting it around frustrating in the long term.
Overall, I’ve been really impressed with the Shark CryoGlow, but as with all beauty tech I’ll hazard that results may vary; mine were noticeable, yes, but it’s a big, daily commitment to ongoing skincare at a fairly high cost. That being said, it’s encouraged better skincare from me all-round, and is more affordable in the long-term than salon treatments, single-use eye masks and a whole lot of pimple patches.

How I tested
I’ve been using Cryoglow for months by the time I sat down to write my review, running a full course of its blemish-busting treatment and making it most of the way through its Better Aging Treatment.
In addition to the Treatments, I tried using the under-eye cooling pads at various temperature settings, testing from day-to-day to see how much (or little!) they reduced the dark circles under my eyes, as well as key specs like the battery life. I tried using the mask at different times of the day to see if it had much of an impact on the immediacy of the results, and even tried using it on a plane!
I’ve been writing for TechRadar for almost four years now, reviewing everything from beauty tech to smart home and wellness devices. I’ve tried different LED face masks, as well as various high-tech skin treatments, to build an idea of what good looks like, always factoring in important factors like price, comfort and longevity.
