Quick Verdict
Shark CryoGlow LED Face Mask (FW312PL)
LED light therapy + under-eye cooling · 4.4★ on Amazon
CryoGlow combines red, blue and deep infrared LED light with something no other LED mask has: built-in, temperature-controlled under-eye cooling. Shark says it’s FDA-cleared and clinically tested by an independent third party. It has four treatments developed with dermatologists: a 6-minute Better Aging mode (red + infrared) to target fine lines and firmness, an 8-minute Skin Clearing mode (blue + infrared + red) for acne and redness, a 4-minute Skin Sustain mode for radiance, and an Under-Eye Revive mode with three chill levels.
- Covers anti-aging, acne and glow in one device
- Unique under-eye cooling feels great
- Short sessions: 4 to 8 minutes
- FDA-cleared and clinically tested
- Results take weeks of daily use
- Pricier than basic LED masks
- Not a replacement for in-office treatments
Best for: Anyone who wants an easy, at-home LED routine for fine lines, breakouts and puffy eyes.
Skip it if: You want fast, dramatic results; LED is slow and steady.

The 4 Treatments, Explained
- Better Aging (6 min): red and infrared light to target fine lines and firmness. Shark reports results from a 12-week study with daily use.
- Skin Clearing (8 min): blue, infrared and red light to reduce acne and redness without acids.
- Skin Sustain (4 min): a quick glow-boosting session.
- Under-Eye Revive (5–15 min): cooling technology with 3 chill levels to visibly tighten tired under-eyes.

How to Use It
- Start with clean, bare skin.
- Choose a treatment and put the mask on.
- Relax for 4–8 minutes; it shuts off automatically.
- Follow with your usual serum and moisturizer, such as ELEMIS Pro-Collagen.
- Use it consistently, ideally daily, for the best results.
Is the Shark CryoGlow Worth It?
If you’ll use it most days, yes. It replaces several single-purpose gadgets and costs far less than a course of professional LED sessions. If you’re unlikely to stick to a routine, the results won’t come, and the price is hard to justify.
