Prof. Dr. med. Ivo Buschmann ist Lehrstuhlinhaber für Angiologie an der Medizinischen Hochschule Brandenburg Theodor Fontane (MHB) und Klinikdirektor der Universitätsklinik für Angiologie am Brandenburgischen Universitätsklinikum. Er absolvierte seine medizinische Ausbildung an der Universität Hamburg, war Max-Planck-Gesellschaft-Stipendiat am Max-Planck-Institut für Herz- und Lungenforschung und hatte leitende Oberarztpositionen an der Charité Universitätsmedizin Berlin Campus Virchow inne, bevor er 2016 zum Lehrstuhlinhaber an der MHB berufen wurde.

Prof. Buschmann ist einer der führenden europäischen Experten für Arteriogenese – das durch Fluss angetriebene Wachstum und die Umgestaltung von Blutgefäßen – mit mehr als 150 begutachteten Veröffentlichungen und mehreren US- und EU-Patenten für Geräte, die das Wachstum von Kollateralgefäßen durch kontrollierte Scherkräfte-Therapie stimulieren. Seine Forschung verbindet mechanische und elektrische Stimulation mit vaskulärer Anpassung, Mikrozirkulation und Gewebeperfusion.

Die Beiträge von Prof. Buschmann bieten den Lesern von PureLift LAB eine gefäßbiologische Perspektive, die unsere bestehenden Autoren aus den Bereichen Klinik, Physiotherapie und chirurgische Anatomie ergänzt – und erklären, wie EMS-Stimulation nicht nur die Gesichtsmuskeln, sondern auch die Mikrozirkulation, die sie versorgt, aktiviert und warum eine intelligente Anwendung auf der Ebene des Blutflusses ebenso wichtig ist wie die Muskelkontraktion.

What's This About:

Shark CryoGlow delivers far more light than PureLift GLOW does, and GLOW does five things CryoGlow cannot do at all, so this is a comparison of different jobs rather than of better and worse.

This article compares the two on what decides the result you actually see, such as:

- 128 mW/cm² against 0.113 mW/cm², and why that is not the whole story

- what the cooling function is cleared to claim and what the page claims

- why neither wavelengths nor irradiance appear where you buy the mask

- what $349.99 against $999 actually buys in each case

- whether owning both makes sense, and in what order

and many more!

Every CryoGlow figure below comes from Shark's FDA filing, because the product page publishes none of them.

Key Points:

CryoGlow is $349.99, carries 480 LEDs at 630, 415 and 830 nm, and is cleared under K242796 for fine lines, wrinkles and mild-to-moderate acne.

Its filing publishes a total of 128 mW/cm² and delivered doses up to 431 J/cm², none of which appears on the page where you buy it.

On light alone CryoGlow delivers far more than GLOW's light layer at 0.113 mW/cm², and we are not going to argue otherwise.

CryoGlow carries no current of any kind, so nothing on it reaches muscle.

The under-eye cooling is cleared to refresh, invigorate and soothe the skin; the product page says it helps visibly tighten under-eyes, which the clearance does not cover.

What CryoGlow is

CryoGlow is a rigid LED mask with 480 LEDs in 160 tri-wick packages, four routines running from four to eight minutes, and a separate under-eye cooling session of five to fifteen minutes.

Shark's FDA filing under K242796 publishes red at 630 nm, blue at 415 nm and infrared at 830 nm, with a total irradiance of 128 mW/cm² across the modes and delivered doses that reach 431 J/cm² for the Better Aging routine.

Those are serious figures, the clearance is real, and at $349.99 with no gel and no consumables it is a straightforward purchase.

It is also the best-selling device of its kind, which is worth saying plainly rather than working around.

Where the figures live

None of the numbers above appear on the product page.

The page publishes weight, cord length, wattage and amperage, and not a single wavelength, irradiance or dose figure.

This is the pattern across the category, and it is the reason we wrote a separate piece on why an output figure without its measurement conditions is not a specification.

Credit where it belongs: the filing is detailed, and a buyer who knows to look can find everything. Most buyers do not know to look.

On light, CryoGlow wins

PureLift GLOW publishes 1.13 W/m² and 678 J/m² over a ten-minute session, which converts to 0.113 mW/cm² and 0.068 J/cm².

Against 128 mW/cm² and doses in the hundreds of J/cm², there is no version of the arithmetic where GLOW's light layer delivers more light, and we publish the conversion so you can check it.

Coverage runs the same way, since a mask treats the whole face at once while a probe treats what you hold it against.

If light is what you want, and specifically if acne or overall texture is the concern, CryoGlow at $349.99 is the better buy and costs a third of what GLOW does.

What GLOW does that CryoGlow cannot

CryoGlow has no electrical current, so nanocurrent, microcurrent and EMS are all absent, and nothing on the device reaches the muscle layer that holds the lower face up.

GLOW carries nine technologies on one dial: Infusion, iontophoresis, nanocurrent, microcurrent, EMS, PDM, PDM++, blue at 465 nm and red at 634 nm, reaching 9 mA at 500 ohms with the diamond-faceted probe.

Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness over twelve weeks of motor-level stimulation (10.1111/jocd.12007), and no mask at any irradiance produces that, because light is not current.

GLOW also runs a serum delivery pass, which CryoGlow has no equivalent of, and works with any water-based serum.

So the choice is between more light across more of the face, and light plus the muscle work plus the serum step in the same ten minutes.

The cooling function, and a claim worth checking

InstaChill is thermoelectric cooling of two contact pads under the eyes, with fans rejecting the heat, and three adjustable levels.

Shark's clearance describes the cooling as intended to refresh, invigorate and soothe the skin, and it sits outside the cleared treatment indication, which covers the LEDs for wrinkles and acne.

The product page says the cooling helps visibly tighten under-eyes in one use, and tightening is not what the cooling function is cleared for.

No temperature is published anywhere, on the page or in the filing, for the function the product is named after.

Cold constricts vessels and reduces the look of puffiness for a while, which is a real and pleasant effect, and it is not the same as tightening.

Owning both

These two devices stack rather than compete, and the order matters.

Run GLOW first on clean skin with a water-based serum, three minutes per side and no longer, then the Infuse pass.

Put the mask on afterwards and let it do the whole-face light dose on skin that has just had circulation brought to it.

Ten minutes plus eight minutes, three to five times a week, is a routine most people can hold.

Which to buy

Buy CryoGlow if acne or texture is the concern, if you want hands-free treatment, or if $349.99 is the budget and light is the priority.

Buy PureLift GLOW if the lower face has started to drop, because that is a muscle question, and if you want the light alongside rather than instead of the muscle work.

Buy CryoGlow first if you can only buy one and your skin concerns sit at the surface, and buy GLOW first if what bothers you is the shape of your face rather than its surface.

This comparison sits inside our full map of the category, where we set out all 33 devices we track, what each one carries and what each brand publishes: Nine Technologies on One Dial, What the Rest of the Market Actually Carries.
