Shark spent decades building vacuums and hair tools before it ever touched skin care, so when the Shark CryoGlow launched at CES 2025, plenty of people raised an eyebrow. A vacuum brand making an LED face mask sounded like a stretch. A year and a half later, the device has earned genuine praise from beauty editors who tested it for weeks at a time, and it has become one of the more talked-about entries in a crowded LED mask market. This guide covers what the mask does, what it does not do, and the details most reviews leave out.
What Is the Shark CryoGlow?
This rigid, hard-shell LED face mask combines three types of light therapy with a built-in cooling feature for the under-eye area. It retails for $349.99 in the United States and runs higher in Canada, typically between $499 and $549 depending on the retailer.
Inside the mask sit 160 tri-wick LEDs, adding up to 480 individual light sources. Each tri-wick LED can switch between red, blue, or infrared light, which is how the mask delivers four separate treatment modes without needing separate attachments or panels.
The Four Treatment Modes Explained
Understanding what each mode does helps set realistic expectations before buying.
Better Aging (6 minutes)
Uses 630nm red light and 830nm near-infrared light to target fine lines and encourage collagen production. Shark’s own 12-week clinical study, run on 60 participants using the mode once daily, reported visible firming results.
Skin Clearing (8 minutes)
Combines 415nm blue light with red and infrared to reduce acne-causing bacteria and calm redness. A separate 12-week study with 59 participants backed this claim.
Skin Sustain (4 minutes)
A quick maintenance mode using all three wavelengths together, meant for daily upkeep once the main 8-week treatment cycle wraps up.
Under-Eye Revive (5 to 15 minutes)
This mode runs independently of the light therapy and focuses purely on the cooling pads, adjustable in length depending on how much de-puffing a person wants.
Shark recommends sticking with one primary mode, either Better Aging or Skin Clearing, for a full eight weeks before switching, since consistency matters more than variety for these treatments.
The Cooling Feature That Sets It Apart
The InstaChill cooling pads are the single biggest reason the Shark CryoGlow stands out from nearly every other LED mask on the market. Built-in pads sit directly under the eyes and offer three adjustable temperature levels, working either alongside a light therapy session or entirely on their own.
Independent testing found visible de-puffing within the first week of consistent use, with continued improvement noticeable by the four-week mark. This matters because under-eye puffiness is one of the top reasons people shop for LED masks in the first place, yet almost no competing mask addresses it directly. Devices from Omnilux and CurrentBody deliver strong light therapy, but neither offers active cooling as part of the experience.
How Shark CryoGlow Compares to Other LED Masks
Price comparisons get thrown around a lot, so here is a clear side-by-side using publicly listed prices at the time of writing:
| Device | Price | Cooling Feature? |
|---|---|---|
| Shark CryoGlow | $349.99 | Yes, built-in |
| Dr. Dennis Gross DRx SpectraLite | $455 | No |
| Therabody TheraFace Mask | $599 | No |
| Solawave Wrinkle Retreat | $349 | No |
| HigherDose Red Light Mask | $349 | No |
At the same price point as Solawave and HigherDose, this mask includes a feature neither of those masks offers, which explains why several reviewers specifically called out the cooling pads as the deciding factor in their recommendation.
Real Numbers Most Articles Skip
Most coverage of this mask repeats the same marketing language without digging into the actual specs. Here is what the hardware delivers:
- Irradiance: Roughly 73 mW/cm² of red light output, which sits on the higher end of dermatologist-recommended power levels for meaningful skin change.
- Battery life: A full charge typically lasts about a week of daily treatments before it needs to be plugged back in via USB-C.
- Weight and fit: The mask weighs about 1.5 pounds and uses an elasticated strap that goes around the back and over the top of the head, which keeps it more secure than lighter, flexible mask designs.
- FDA status: The device is FDA-cleared, not simply FDA-registered. Cleared status means the manufacturer submitted data showing the device is safe and effective for its stated use, which is a meaningfully higher bar than registration alone.
What Nobody Tells You About Owning One
After combing through reviews, retailer feedback, and forum discussions, a few practical realities rarely make it into glossy product write-ups.
- The design looks unsettling, and that is normal: Nearly every reviewer who tested it admitted the glowing, hard-shell design looks strange, even a little frightening, in photos. This is true of essentially every LED mask on the market, not a flaw unique to Shark.
- Storage takes up more space than expected: Because the shell is rigid rather than flexible, it does not fold flat like fabric-based masks. A dedicated storage bag comes included, but anyone with limited counter or drawer space should account for the bulk before buying.
- Skin reactions, while uncommon, do happen: A small number of buyers reported redness or irritation after several weeks of regular use, particularly around the cooling pad contact points. Anyone with highly sensitive skin should patch test and start with shorter sessions.
- Retail bundles vary significantly: Costco has periodically bundled the mask with a charging stand and a silk pillowcase, sometimes with an added store credit promotion, which can meaningfully change the value compared to buying direct from Shark.
- It should not be your only skin care step: Reviewers who saw the best results paired the mask with a consistent basic routine, cleanser, moisturizer, and sun protection during the day, rather than treating it as a stand-alone fix.
Who Should Consider This Mask
This device tends to make the most sense for people who:
- Want to address both fine lines and acne without buying two separate tools
- Deal with morning under-eye puffiness and have not found relief from creams or cold spoons
- Prefer a guided, remote-controlled routine over guessing at treatment times
- Are comparing options in the $300 to $400 range and want the most features for that budget
It may be less suited to anyone who travels frequently and needs something foldable, since the rigid shell is bulkier than flexible alternatives.
Safety Notes Worth Reading Before You Buy
LED light therapy is generally considered low risk, but a few precautions apply to this mask and similar devices:
- Avoid use if pregnant, without checking with a doctor first, since most manufacturers have not tested devices on pregnant users.
- Speak with a dermatologist first if taking photosensitizing medication or being treated for a history of skin cancer.
- People with epilepsy or certain inherited eye conditions should get medical clearance before using any flashing-light device.
- Stop use immediately if unusual irritation develops around the cooling pad area and allow skin to fully recover before trying again.

It is FDA-cleared, meaning the manufacturer submitted clinical data proving the device is safe and effective for its intended use, which is a stronger designation than simple FDA registration.
3. How long does it take to see results with the Shark CryoGlow?
Shark’s clinical studies measured results over 12 weeks, though many users report visible under-eye de-puffing within the first one to two weeks of consistent use.
4. Can I use the Shark CryoGlow every day?
Yes, daily use is recommended for the first eight weeks on either the Better Aging or Skin Clearing mode, followed by the shorter Skin Sustain mode for ongoing maintenance.
5. Does the Shark CryoGlow work for acne?
The Skin Clearing mode uses blue light to target acne-causing bacteria alongside red and infrared light to calm inflammation, with Shark’s clinical study reporting improved complexion over four weeks.
6. What makes the Shark CryoGlow different from other LED masks?
Its built-in InstaChill cooling pads are the main differentiator, since most competing masks in the same price range offer light therapy alone without any cooling feature.
7. Is the Shark CryoGlow comfortable to wear?
Most reviewers describe it as comfortable and secure thanks to its elasticated strap, though the rigid shell makes it bulkier to store than flexible fabric-based masks.
8. Can the Shark CryoGlow cause skin irritation?
Irritation is uncommon but has been reported by a small number of users, usually around the cooling pad contact points, so a patch test is a reasonable first step for sensitive skin.
9. Where is the best place to buy the Shark CryoGlow?
It is available directly from Shark, along with Sephora, Ulta, Costco, Sam’s Club, and Dermstore, with Costco occasionally offering bundle deals that add extra value.
10. Do I need other skin care products alongside the Shark CryoGlow?
Yes, reviewers who saw the strongest results paired the mask with a basic routine of cleanser, moisturizer, and daily sun protection rather than relying on the device alone.
Final Thoughts
The Shark CryoGlow earns its growing reputation by doing something most LED masks do not: pairing genuine light therapy with real cooling technology in one device. It will not erase every fine line or clear every breakout overnight, and the rigid design takes some getting used to, both on the face and in storage. But for anyone comparing options in the $300 to $400 range, the combination of three light wavelengths, four guided treatment modes, and built-in under-eye cooling makes a strong case for why this mask keeps showing up in serious skin care routines rather than fading out as a passing trend.
