Does the Shark CryoGlow Work? 12 Weeks of Daily Use

Who is the Shark CryoGlow for, and who should skip it?

The CryoGlow is built for adults who already have a skincare routine and want to add an at-home light therapy step rather than replace their products. If your concerns are early fine lines, occasional breakouts, or puffy, tired-looking under-eyes, this one device covers all three.

Skip it if you want instant results. The clinical results Shark cites come from 12 weeks of daily use. It is also not a fix for severe acne, which calls for a dermatologist. And if you only want a basic red light device, you would be paying for cooling hardware and extra modes you won't use.

What sets it apart from other LED masks?

The main difference is the under-eye cooling. Shark says the CryoGlow is the only LED face mask with built-in, temperature-controlled under-eye cooling. Clip-on chill pads sit under the eyes, and you pick one of three cooling levels for a 5 to 15 minute Under-Eye Revive session. Shark claims it visibly tightens the under-eye area after one use. Most competing masks offer light alone.

The mask also has some outside backing. It is FDA-cleared, and Shark says its independent third-party clinical testing covered 119 participants. Shark also calls it the most awarded LED mask in the US, based on its count of 2025 skincare awards from US beauty publications. That is the company's own tally, but it lines up with how often the mask appeared in editors' roundups this year.

In our video review, the remote stood out most in daily use. You choose treatments and cooling levels from a handheld remote instead of pressing buttons on the mask, which makes sessions easier while you're lying back on a couch.

What do the treatments and specs mean in practice?

The mask runs four treatments that Shark says it developed with dermatologists:

• Better Aging, 6 minutes: red and infrared light. Shark's 12-week study of 60 subjects using it once a day reported fewer fine lines and firmer skin.
• Skin Clearing, 8 minutes: blue, red and infrared light. A 12-week study of 59 subjects using it once a day reported less acne and redness, with no acids or prescriptions.
• Skin Sustain, 4 minutes: red, blue and infrared light, for general radiance and upkeep. In our video review, we treated it as the shorter mode to switch to after a full cycle of Better Aging or Skin Clearing.
• Under-Eye Revive, 5 to 15 minutes: cooling with three chill levels.

Physically, the mask measures 7.99 x 5.89 x 8.63 inches and weighs 1.49 pounds. It is a rigid shield that sits slightly away from your face rather than a soft, flexible mask that hugs the skin. In our video review, this helped the light reach the face evenly, but it also means you'll want to sit back or lie down during a session. The mask charges over USB-C, and the box includes the mask, clip-on chill pads, the remote and a charging cable.

The listing doesn't give LED wavelengths, LED count, battery life or charge time. If any of these matter to you, check the manufacturer's product page before you buy.

What are the limitations and trade-offs?

• Time: Sessions last 4 to 8 minutes, plus up to 15 minutes if you add under-eye cooling. Shark's results assume daily use for 12 weeks, so skipped sessions will likely mean weaker results.
• Not hands-free: Because the mask is rigid, it isn't something to wear while walking around or doing chores.
• Results vary: Shark's own footnotes say individual results may vary, and the studies involved fairly small groups of about 60 people each.
• Missing specs: The missing battery and wavelength details make it harder to compare with rival masks on paper.
• Routine order: Shark says to use it on a clean, dry face before applying any other skincare. That can mean rearranging your morning or evening routine.

How does it compare with the alternatives?

Buyers usually compare three types of products. Flexible silicone LED masks are lighter and easier to wear while moving around, but most offer light therapy only, with no cooling. Budget LED masks are much cheaper, but they rarely have FDA clearance or published clinical data, and their light output is often unclear. In-office red light sessions at a MedSpa are professionally run, but you pay per visit. If you'd go regularly, a daily at-home device can make more sense over time.

The CryoGlow's case rests on combining three things in one device: anti-aging and acne modes with published study details, plus under-eye cooling. If you'd otherwise buy a separate eye-cooling tool, that counts in its favor. If your budget for skincare devices is modest, it is more than you need.

What do owners say?

The CryoGlow has a 4.4 out of 5 rating from 1,029 Amazon ratings. It ranks #3 in Wrinkle & Anti-Aging Devices, which shows steady demand for a model first listed in March 2025. When reading reviews, look for owners who used it daily for at least 8 to 12 weeks. Short-term impressions say little about light therapy results.

Is it FSA or HSA eligible?

The listing says the FW312PL may be eligible for FSA and HSA benefits, depending on your health plan administrator's requirements. Your administrator may ask for extra documentation, such as a letter of medical necessity. Confirm eligibility with your plan before you count on it.

Final verdict: is the Shark CryoGlow worth it?

The CryoGlow is one of the better-documented at-home LED masks you can buy. It is FDA-cleared, has published clinical study details, and has an under-eye cooling feature that sets it apart from other masks. The remote makes daily use easier, and owner ratings are strong. The trade-offs are the daily time commitment, a rigid design that keeps you seated, and missing specs for battery and wavelengths. If you'll use it most days for a few months, it's worth it. Score: 7.8/10.
