Shark CryoGlow LED face mask review: red light plus cooling, and the trade-offs
2 masks, $299.99 to $379.99. The CryoGlow is the cheapest way into an FDA-cleared mask with extras: under-eye cooling, a 2-year warranty and a 60-day return window, for $299.99. Its FDA file states the highest output of any mask we track, 128 mW/cm² in every mode, and clears it for both wrinkles and acne.
Two catches. Shark's product page doesn't give its wavelengths; you'll find them (415, 630 and 830 nm) only in the 510(k) summary. And the most common owner complaint is battery life.

Output: "claimed" is Shark's figure with no distance stated.
Verdict
you want a cleared mask for around $299.99 that handles breakouts as well as fine lines, with a long return window, and the cooling sounds like something you'd use.
you need a mask that lasts several sessions per charge, or you'd rather buy from a brand that puts its specs on the product page. The masks ranking has options that publish everything up front.
Alternatives worth considering
- HigherDOSE Red Light Face Mask, $349: 630 and 830 nm, 50 mW/cm² (red 26 + NIR 24) stated, a 120-day money-back guarantee. HigherDOSE mask review.
- Omnilux Clear, $395: 415 and 633 nm, cleared for acne only, with eye shields built in, 2 years device, 2 years controller. Omnilux Clear review.
- Bon Charge Red Light Face Mask, $349: 630 and 850 nm, 40.8 mW/cm² stated. Bon Charge review.
Specs: in the FDA file, not on the product page
The 510(k) summary lists red at 630 nm, blue at 415 nm and infrared at 830 nm (each ±10 nm), 480 LEDs in 160 three-color packages, and 128 mW/cm² total in every mode. Shark's product page gives none of those numbers; it names the colors and the minutes. That output figure is the highest among the masks we track; next is the Therabody TheraFace Mask at 73. Nobody independent has measured either, and no distance is given.
| Program | Light (FDA file) | FDA time | Shark says |
|---|---|---|---|
| Better Aging | Red + infrared, 64 + 64 mW/cm² | 6.4 min | 6 min |
| Skin Clearing | Three steps of blue, red and infrared | 8.4 min | 8 min |
| Skin Sustain | Blue, red and infrared | 4.3 min | 4 min |
The wavelengths line up with the studies: 630 nm red and 830 nm near-infrared are the pair most mask trials used, and blue at 415 nm is the acne wavelength (what the research used).
The cooling part
CryoGlow's twist is two chilled pads under the eyes, run on their own or alongside the light. Shark's page says the cooling helps "visibly tighten under-eyes in one use." The FDA file is more modest: the cooling is "for purposes of refreshing/invigorating/soothing the skin only and does not impact the device's safety or effectiveness" for wrinkles or acne (FDA summary). Treat it as comfort, not treatment.
Owners like it: on Amazon, 78 mention eye cooling (67 positive, 11 negative).
"I’ve been using this for almost a year and I still absolutely love this mask. It’s made of such amazing quality it’s super strong and durable. I love the eye cooling effect which is what sold me on it to begin with." 5-star review, Aug 2026, amazon.com
CryoGlow vs CryoGlow Plus
The CryoGlow Plus costs $379.99 against $299.99. Shark says it adds "120% improved LED coverage around the crow's feet area," light around the lips and "optimized battery performance" compared with an earlier model. The 510(k) summary names only "CryoGlow (FW3XXXX)"; the FDA listing database puts the Plus under the same number, K242796. The Plus page publishes no output, LED count or session times. If battery life is what put you off the original, the Plus is the one to look at; otherwise the original does the same job for less.
FDA: cleared for wrinkles and acne, filed by Shark
SharkNinja Operating, LLC filed K242796 itself, under product codes OHS (wrinkles) and OLP (acne); the FDA decision came on Nov 27, 2024. The indications, word for word: the mask "emits energy in the red and infrared light spectrum for the treatment of fine lines and wrinkles and in the red, blue, and infrared light spectrum for the treatment of mild-to-moderate inflammatory acne." Among the 21 cleared masks we track, only 3 brands filed their own (Shark, Therabody and FOREO); the rest were filed by a factory or another company. More on that: FDA-cleared LED masks.
Shark vs Omnilux
| Shark CryoGlow | Omnilux Contour Face | |
|---|---|---|
| Wavelengths | 415, 630 and 830 nm (FDA file only) | 633 and 830 nm |
| Cleared for | Wrinkles and acne | Full-face wrinkles |
| Stated output | 128 mW/cm² total | about 30 mW/cm² |
| Session | 4-8 min (Better Aging 6, Skin Clearing 8, Skin Sustain 4) | 10 min |
| Extras | Under-eye cooling | Matching neck mask sold separately |
| FDA 510(k) | K242796, Nov 27, 2024 | K191629, Sep 12, 2019 |
| Warranty | 2 years (Limited Warranty) | 2 years device, 1 year controller |
| Returns | 60-day money-back guarantee | 30 days for LED devices |
| Price | $299.99 | $395 |
Shark wins on price, acne coverage, return window and features; Omnilux keeps it simple and puts its wavelengths on the box. More in the Omnilux review.
How often to use it
Each program runs 4 to 8 minutes and switches off. The FDA summary lists Better Aging and Skin Clearing as daily for at least 8 weeks, with Skin Sustain daily after that. The clinical study Shark publishes ran 12 weeks of once-a-day use, with 60 people in Better Aging mode and 59 in Skin Clearing, per Shark's summary of it. More isn't better with LED light: researchers describe a "biphasic" dose response, and in one mask trial two sessions a week did as well as three (Bragato 2025; what trials show).

Questions people ask
How often should I use Shark CryoGlow?
The FDA summary lists daily use for at least 8 weeks for the anti-aging and acne programs. Each runs 4 to 8 minutes and stops on its own; follow the schedule in Shark's instructions rather than adding sessions.
Is the Shark LED mask a good one?
It's FDA-cleared for wrinkles and acne, well rated on Amazon (4.4/5), and well priced with a 60-day return window. The weak points: the specs live only in the FDA file, and owners often complain about battery life.
What is better, Omnilux or Shark?
Shark for price, cooling, acne and returns; Omnilux for simplicity and published wavelengths. Both use the 630 to 633 nm red and 830 nm near-infrared pair from the studies.
What are the downsides of using an LED face mask?
Results are small and slow, the evidence for wrinkles is limited, and eyes need protecting, especially from blue light. See benefits and safety.
