I’ve had a Solawave red light therapy wand in one of my bathroom organizers for probably two years now. I really wanted to love it, but it just didn’t provide noticeable enough results for me to remember to use it. So it should say something that I never forgot to use the Shark CryoGlow red light mask in the few months that I was testing it — and beyond.

The Shark CryoGlow mask’s $349.99 price tag isn’t exactly cheap, but it isn’t expensive compared to the other top red light masks on the market. The price feels much fairer when the CryoGlow has a few unique flexes that separate it from popular competitors like the $395 Omnilux mask and $349 Solawave mask.

Shark hair tools like the FlexStyle have cemented themselves as formidable fixtures in the hair care world for years now. But the CryoGlow is Shark’s first attempt at esthetics — one carefully designed over time after input from dermatologists, evidence from clinical trials, and customer feedback about other red light devices on the market. I learned all about its lore at SharkBeauty’s launch event for the mask in January 2025, then brought one home to test for myself.

What does the Shark CryoGlow mask do?

The Shark face mask targets fine lines, acne, dark circles, and generally uneven skin texture. These are the main benefits of red light therapy (and blue light and infrared light), often yearned for when even the most devout skincare routines aren’t doing enough.

The CryoMask is lined with 160 interlocking tri-wick LED bulbs, spanning all corners of the face and even a little under the jaw. Everyone calls it an LED mask, but if you want to get fancy, it’s technically iQLED.

That 160 beats the 132 LEDs of the Omnilux mask or the 14 LEDs of the Solawave wand, so that’s noteworthy on its own — but the “tri-wick” thing is crucial, too. Tri-wick means that every single one of those bulbs can emit each wavelength, so you’re getting full-face light coverage regardless of the setting. Scientifically, this would be clocked in terms of irradiance: a measurement of power density at the source of the LED. The Shark CryoGlow hits a maximum radiance of 128mW/cm² compared to the 30mW/cm² of the Omnilux.

(The bulbs in several competing masks can’t all illuminate simultaneously because they’re either single-wick or bi-wick, meaning half turn off when their designated color isn’t being used.)

The nanometer measurement of each wavelength plays a huge role in skin penetration. The Shark CryoGlow uses a 415nm blue light targeting the skin’s surface layer and 630nm red light with 830nm infrared to travel to the deeper, cellular layer of skin.

So, what’s the difference between red light and blue light? All you really need to determine is the skincare concern you’d like to target, then scroll through the CryoGlow remote’s settings to choose one. Shark designed the two main settings to be used for an initial eight-week session with daily use.

• Better Aging mode: This mode stimulates collagen production and promotes plumping under the skin, making it the best setting for targeting fine lines and wrinkles. Here, the mask administers a combination of red and infrared light simultaneously for six minutes.

• Blemish Repair mode: This is used to kill acne-causing bacteria and improve skin clarity and texture on the top layer of the skin. Here, the mask administers a consecutive concoction of blue light with infrared for a few minutes, then blue and red light together for a few minutes, then red light + infrared for a few minutes. It takes eight minutes total.

• Skin Sustain mode: This is used to maintain your results and get a daily boost of brightness after your initial eight-week cycle is over. Skin Sustain administers blue light, red light, and infrared light simultaneously for a total of four minutes.

Each cycle’s timing was calculated based on the wavelength combination of that setting — it’s a much more precise approach than Googling “how long you should use red light therapy for.” During the science part of the discussion at the launch event, it clicked for me: The momentary swipe of a red light wand with a one-inch surface is a really small amount of true LED exposure. This cleared up a lot of my confusion about my lack of Solawave wand results when it worked well for other people.

The Shark mask isn’t super chill to wear, but it’s quick

I doubt there’s anyone out there researching the best red light mask to buy and expecting to not look like Dwight in that episode of The Office where he cuts off the CPR dummy’s face. It’s just part of the game.

Still, the Shark mask definitely isn’t the chicest or slimmest mask I’ve seen. It’s not foldable like some other models, and is also a little clunky when it comes to storage. The heavy packer in me could not take this thing in a suitcase, even though it comes with a carrying pouch.

There’s definitely no answering the door like this, but you know what? The horror fanatic in me does not mind casually walking around the apartment looking like Jason Voorhees for a few minutes (though I am a proud Michael Myers girlie at heart — argue with yourself).

The CryoGlow doesn’t necessarily feel heavy if you’re just scrolling on your phone while wearing it. But it does start to feel a little bulky if you’re performing a real task that requires looking down. I kept trying to feed my cats during morning CryoGlow sessions and had to strain my neck to accurately scoop the wet food into the bowls on the counter.

The mask itself is rechargeable and doesn’t need to be plugged into the wall while being used; instead, it needs to be charged about every three days. Though the remote and its cord mostly stay out of the way, it would be sick if it were cordless.

The thing is, no Shark CryoGlow session lasts longer than eight minutes. You’re not really being inconvenienced for long. The fans are whooshing right in your ear, but it’s not so loud that you can’t hear a conversation or watch TV. Honestly, the hardest part of wearing it is sitting there with air-dried skin without something moisturizing on it — Shark recommends a clean, dry face for light to best penetrate, but the itchy feeling post-cleansing makes me want to tear my whole face off.

Shark CryoGlow results after three months

I kind of stopped giving a shit about how I look without makeup after my frontal lobe developed. But the CryoGlow marks a time in my life when I genuinely feel cute bare-faced. I truly feel like there’s more of an inherent glow and evenness to my skin after my full CryoGlow session than I’ve ever had before.

But I know everyone is most interested in the full transformation, so fine, I’ll give you a “before” picture. But before I expose myself like that, I’m entitled to show the “after” picture first.

I promise my skin is smooth in this photo — the only leftover “spots” are discoloration from previous giant pimples. I’ve accepted the fact that I need to pay for more microneedling to uproot those.

Does the Shark mask work on acne?

Every little kid dreams of growing up, having a mental breakdown about adult acne at age 30, and publishing a close-up photo of it in an online article for work. But I have to showcase the full transformation to show that yes, the Shark CryoGlow mask really does keep acne formation at bay.

For context, I’m 30 years old and never really struggled with acne… up until about four years ago. It’s been a battle to keep my chin, jawline, and cheeks clear since then. I was living in fear of waking up with a new pimple cooking after I had just gotten the last one to simmer down. Mine were in areas typically associated with fluctuating hormones.

All of that was happening while never skipping my nighttime skincare routine and attending a few microneedling appointments, my last of which was three months before I started testing the Shark mask. While I do believe my religious Tretinoin use has improved the texture of my skin, it was outnumbered by hellbent acne. The only true slowdown of pimples I experienced started a month into using the CryoGlow. I went from a new painful crater popping up almost every day to maybe one or two every two weeks.

(The only other changes I recently made were spritzes of hypochlorous acid after waking up or going outside, and taking a Zinc supplement after TikTok suggested that could help with acne.)

The CryoGlow is excellent at fighting bacteria that causes acne and reducing redness of the ones that do exist, it doesn’t really reduce acne scars or deep leftover red spots — and doesn’t claim to. Those just seem to be stubborn little marks that probably require an in-office facial treatment.

Does the Shark mask work on fine lines?

Yes, the Shark mask made the fine lines in some areas of my face less noticeable.

The needlelike presence of my forehead wrinkles had become increasingly prominent in the last few years of my 20s. Makeup was making the texture even more noticeable, especially when it began creasing after a few hours. I finally started getting occasional forehead Botox about two years ago, and let me tell you: Botox is that girl. But the baby wrinkles soon creep back in, and keeping up with it gets expensive.

I’m fully convinced that the Shark CryoGlow mask was key in mellowing out my forehead lines enough to keep me out of the Botox chair for months longer than I’m “supposed” to. (For context: My last Botox appointment was five months before testing the Shark CryoGlow, and I did not get any Botox treatments while testing the mask.)

Concealer and powder were blending so much more seamlessly than they previously did when I was overdue. There’s nothing like that post-Botox forehead plumpness, but the CryoGlow provided the next best thing for me — a smoothness that no serums in targeted Instagram ads are going to achieve.

Unfortunately, the CryoGlow didn’t have the same blurring effect around my crow’s feet. God forbid you’re someone who LAUGHS.

Does the Shark mask work on under eyes?

I definitely think I look less like a corpse on the days when I use the CryoGlow’s under-eye chill pads. This is where the “Cryo” part of the title comes in: the mask is mimics cryotherapy, which can lower inflammation of the tissue using targeted low temperatures. The chill pads can cool at three different levels of chilly during an LED session, or can be used without lights.

The CryoGlow’s de-puffing effects don’t feel super long-lasting — keep in mind that this is more of an elevated ice roller routine each morning than a heavy-duty under-eye treatment. You can’t expect hollowness to permanently fill out, but I can vouch for the brightening effect. At any rate, the cool metal plates feel amazing when you’re a zombie in the morning.

Is the Shark CryoGlow Mask worth it?

Shark’s face mask visibly proved its worth in my skincare routine, and I’d recommend it to just about anyone.

The way my acne cleared up during the eight-week period was easily the most palpable result. I’m not saying you’ll never get a pimple while using the mask, but I do think the CryoGlow’s red, blue, and infrared concoction is extremely effective at mitigating the amount of acne popping up. Similarly, because its wavelengths can dig further into the skin than topical skincare, it’s a more powerful tool for dulling fine lines than any retinols or retinoids I’ve tried. With less-dead under eyes as the cherry on top, I am glowier and more comfortable bare-faced now than I was pre-mask.

The Shark CryoGlow mask may or may not be able to accomplish these exact results for everyone from scratch. It probably depends on the skin you’re working with to start, and the consistency of the rest of your skincare routine. The CryoGlow is definitely a slight financial investment up front, but most people deep in skincare mode know that no route to glass skin is cheap. Plus, regular CryoGlow use could end up saving you money over time.
