Shark CryoGlow Review: Does This Under-Eye Cooling LED Mask Really Work?

 LED face masks have become a staple of the at-home skincare device category, but most stop at light therapy alone. 

The Shark CryoGlow takes a different approach by pairing red, blue, and infrared LED treatment with built-in under-eye cooling — a combination designed to address both visible aging and one of the most stubborn concerns in skincare: tired, puffy under-eyes. 

The CryoGlow represents one of the more feature-dense options currently on the market.

This review breaks down how the device works, what its clinical testing actually shows, who it's best suited for, and how it compares to other LED masks we've covered.

Shark CryoGlow Review: Does This Under-Eye Cooling LED Mask Really Work?

What Is the Shark CryoGlow?

The Shark CryoGlow↗ is an LED face mask developed by SharkNinja that combines two technologies in a single device: iQLED light therapy and InstaChill under-eye cooling. 

It was developed in collaboration with dermatologists and is FDA-cleared, with clinical testing behind its primary treatment modes.

Key Features

iQLED Technology: Uses precise tri-wick LED sequencing to deliver red, blue, and infrared light across the full face without gaps or hot spots.

InstaChill Cold Technology: Built-in cooling pads use the Peltier effect — combined with fan-assisted heat dispersion — to deliver adjustable cooling directly to the under-eye area.

Multiple Treatment Modes: Includes dedicated programs for anti-aging, blemish repair, and skin maintenance, each with a pre-set treatment duration.

Remote Control Operation: All modes, cooling levels, and session timing are controlled via an included remote.

USB-C Charging: Rechargeable lithium-ion battery with USB-C charging for cordless use.

How the Treatment Modes Work

The Shark CryoGlow↗ offers several pre-programmed treatments, each targeting a different concern.

Better Aging Treatment

A 6-minute session combining red and infrared LED light, designed to minimize the appearance of fine lines and firm sagging skin. 

That mode relies on the same general mechanism used across red light therapy devices — red light wavelengths are absorbed in the dermis, where they're believed to support collagen production and improve skin firmness over time.

Skin Clearing (Blemish Repair) Treatment

An 8-minute session combining blue, red, and infrared LED light, aimed at reducing acne and redness for a clearer, more even complexion. 

Blue light is commonly used in acne treatment devices for its effect on acne-related bacteria, while the red and infrared components support overall skin tone.

Skin Sustain Treatment

A shorter 4-minute maintenance session using red, blue, and infrared LEDs together, intended to preserve results between more intensive treatments and support overall skin radiance.

Under-Eye Revive Mode

A standalone cooling-only mode (no LEDs) running for 5, 10, or 15 minutes, designed purely for soothing, depuffing, and relaxation — useful as a quick reset in the morning or as a wind-down step at night.

Clinical Testing: What the Data Shows

One of the more notable aspects of  The Shark CryoGlow↗ is that its core treatment modes have been backed by dedicated clinical studies rather than relying solely on the general research behind LED therapy as a category.

The Better Aging Treatment was evaluated in a 12-week clinical study with 60 participants using the mode once daily, with improvement in fine lines and firmer skin reported by week 8.

The Skin Clearing Treatment was evaluated in a separate study with 59 participants, with clearer skin and reduced acne and breakouts reported after 4 weeks of once-daily use.

As with any skincare device, individual results vary based on skin type, consistency of use, and baseline skin condition. 

These studies reflect manufacturer-sponsored testing and should be considered alongside your own expectations and skin goals.

Pros and Cons

-Combines LED light therapy and under-eye cooling in a single device, reducing the need for separate tools

-Full-face tri-wick LED coverage avoids gaps or hot spots common in lower-density masks

-Multiple dedicated modes allow targeting different concerns (aging, acne, maintenance) without buying separate devices

-FDA-cleared and developed with dermatologist input

-Cordless, rechargeable design with remote control for ease of use

-Treatment time commitment across multiple modes may not suit those looking for a single quick daily step

-Not suitable for individuals on photosensitizing medications or with certain eye conditions — always review the safety information before use

This device is best suited for people who want to address more than one concern with a single tool — particularly anyone dealing with both visible signs of aging and under-eye puffiness or tiredness. 

It's also a strong option for those who've found single-purpose LED masks effective but want to add a dedicated acne-clearing mode or cooling step without purchasing multiple devices.

Safety Considerations

Before using The Shark CryoGlow↗ , it's important to review the manufacturer's safety guidance:

-Avoid use if taking medications or supplements that cause photosensitivity (such as isotretinoin or doxycycline)

-Avoid use if you have retinal or macular disease, ocular albinism, or other light-sensitive eye conditions

-Avoid use on skin that hasn't fully healed from recent facial treatments, including neurotoxin injections, dermal fillers, microneedling, laser treatment, or chemical peels

-Discontinue use immediately if you experience discomfort

As with any at-home device, consulting a dermatologist first is recommended if you have an existing skin condition or are unsure whether the device is appropriate for you.

Final Verdict

The Shark CryoGlow↗ stands out in a crowded LED mask market by addressing two concerns — visible aging and under-eye fatigue — in a single, clinically tested device. 

While it carries a higher price point than basic LED masks, the combination of full-face tri-wick coverage, dedicated treatment modes, and built-in cooling makes it a strong option for anyone looking to consolidate their at-home skincare device routine rather than managing several separate tools.
