Buyer comparison
Shark CryoGlow vs Ulike ReGlow
CryoGlow's defining feature is under-eye cooling alongside red, blue and near-infrared light. ReGlow's defining choice is a broader published output set—blue, yellow, red and near-infrared—without CryoGlow's cooling system. Choose by the feature you will use, not by an unsupported claim that more modes guarantee better outcomes.

Key differences and technology
| Decision point | Shark CryoGlow FW312 — Blue Frost | Ulike ReGlow UM10 |
|---|---|---|
| Published light specification | 480 LEDs: 415 nm blue, 630 nm red and 833 nm near-infrared. | 465 nm blue, 590 nm yellow, 630 nm red and 830 nm near-infrared outputs. |
| Distinctive hardware | Integrated under-eye cooling and eye shields. | Four published light outputs and a wearable mask format. |
| Evidence boundary | Technical and regulatory documentation is stronger than exact-product outcome evidence. | Technical and nonclinical documentation is stronger than exact-product outcome evidence. |
CryoGlow wins the cooling use case because ReGlow does not offer an equivalent integrated cooling feature. ReGlow wins the wavelength-flexibility use case on paper because it adds a published yellow output. That is a feature comparison, not proof of superior results.
Price and value
No stable governed price is recorded for either product. Use the live offers to compare the cost of the feature that matters: cooling on CryoGlow or the additional yellow-light option on ReGlow. Treat discounts as temporary and do not infer efficacy from price.
Evidence strength
The current governed evidence supports the identity, wavelengths, programs and safety framing of both devices. It does not support a universal outcome winner. CryoGlow has a clearer public FDA regulatory summary; ReGlow's exact-product clinical performance is also not established by independent controlled trials in the reviewed evidence.
Safety and limitations
Both are light-emitting home devices. Follow the exact manual, use the supplied eye-protection design as directed, and seek medical advice for photosensitivity, photosensitizing drugs or relevant skin conditions. ReGlow's extra output does not remove those precautions; CryoGlow's cooling is not a substitute for safe light use.
Best for—and who should skip
Choose Shark CryoGlow FW312 — Blue Frost if…
- Under-eye cooling is a real purchase priority.
- You want a public regulatory summary tied to the device family.
- Three core light bands cover your intended routine.
Choose Ulike ReGlow UM10 if…
- You want four published outputs, including yellow light.
- You prefer ReGlow's program flexibility over cooling.
- Its live offer is the better fit for your budget and intended use.
Who should skip or reconsider
- Skip both if you expect exact-device clinical certainty.
- Skip CryoGlow if you would not use the cooling feature but would pay more for it.
- Skip ReGlow if the added yellow output is not meaningful to your routine.
