Daniel Grinberg, MD, FACS, ist ein von der Ärztekammer zertifizierter Hals-Nasen-Ohren-Arzt und Kopf-Hals-Chirurg bei ENT and Allergy Associates in West Nyack, NY. Er erwarb seinen medizinischen Abschluss an der Columbia University College of Physicians and Surgeons, absolvierte seine Facharztausbildung in Hals-Nasen-Ohren-Heilkunde am New York University Medical Center und ist Assistenzprofessor an der Mount Sinai School of Medicine. Er ist Fellow sowohl des American College of Surgeons als auch der American Academy of Otolaryngology.
Dr. Grinbergs Perspektive als Kopf-Hals-Chirurg bietet den Lesern von PureLift LAB eine erweiterte klinische Sichtweise — er verbindet die EMS-Anwendung zu Hause mit der zugrunde liegenden medizinischen Anatomie mit derselben wissenschaftlichen Genauigkeit, die wir auf jede Gerätespezifikation anwenden.

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.

The honest answer is that almost nobody publishes enough information for the question to be answerable, and that the strongest setting you own is rarely the one you should be using.
This article covers what actually decides the answer, such as:
- what the published figures across the category actually are
- why a current figure without a load is not a specification
- the difference between raw output and what reaches tissue
- why the highest setting is usually the wrong setting
- what to ask instead of which is strongest
and many more!
We publish the highest figures in this comparison and we still think strength is the wrong thing to buy on.
Key Points:
Published consumer microcurrent outputs run from about 200 microamps to 680 microamps, all far below the level that contracts a muscle.
Ya-Man files 3.22 mA at 500 ohms with the FDA, and PureLift publishes 7 mA at 500 ohms on Face and Pro and 9 mA on Pro Plus and GLOW.
A milliamp figure with no stated load cannot be compared with one that has a load, which rules out most of the category from any honest ranking.
Pulse width matters as much as current, because charge is current multiplied by duration, and almost nobody publishes it.
Comfort decides whether you keep using a device, and an unused device delivers nothing whatever its ceiling.
What the figures actually are
Among the devices that publish anything at all, Solawave gives about 200 microamps, ZIIP publishes 309, NuFACE files 335 with the FDA, 7E publishes 350 at 500 ohms, Therabody gives 500, Skin Gym quotes a range to 500 and FOREO publishes 680.
Every one of those sits in the microamp band, thousandths of the current that produces a muscle contraction, and most of those manufacturers acknowledge as much. 7E states plainly in its own FAQ that true microcurrent cannot cause a physical or visual manipulation of the muscle.
Above that band, Ya-Man's FDA filing for the Medi Lift PLUS publishes 3.22 mA at 500 ohms, and PureLift publishes 7 mA at 500 ohms on Face and Pro, 7.7 mA on Pro Edition and 9 mA on Pro Plus and GLOW.
We have collected every figure we could find, and where each one is published, in one table covering 33 devices.
Why the load is the whole problem
Current through skin depends on the resistance it meets, so the same device measured into a low resistance reads higher than into a high one, and both readings are honest.
That is why a figure quoted without a load is not a specification. It is a number with no conditions attached, and two devices quoting the same number can behave completely differently on a face.
Of 33 devices we track, six publish an output figure on their own product page and two state the load. So a ranking of the strongest device in this category would mostly be a ranking of marketing confidence.
When you ask a brand for output, ask for the load in the same sentence, and treat the answer as informative either way.
Raw output against delivered charge
Tissue responds to charge, which is current multiplied by the duration of the pulse, so a device quoting a high current with a very short pulse is doing something quite different from one quoting the same current with a long one.
PureLift publishes a 4 microsecond pulse width across the range, which is short, paired with a higher current. Ya-Man's filing gives pulse widths from 52 to 192 microseconds at a lower current. Those two devices are not simply stronger and weaker than each other.
Almost nobody else in the consumer category publishes pulse width at all, which makes a genuine comparison impossible even between two brands that both quote milliamps.
Ward and colleagues set out the thresholds separating sub-sensory, sensory and motor stimulation, and crossing into the motor band is what changes the category of effect rather than the size of the number.
Why the top setting is not the target
Everything above the level you find comfortable goes unused, because sessions that feel unpleasant stop happening, and a device in a drawer has an output of zero.
Papaiordanidou and colleagues found stimulation conditions that produced fatigue rather than gain, which is a reminder that harder is not a synonym for better in any stimulation protocol.
Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness across twelve weeks at motor-level stimulation, and the variable that did the work was repetition across three months rather than maximum intensity.
The right target is a firm, comfortable level you can hold for three minutes a side, raised gradually as tolerance builds.
What comfort engineering actually is
A fixed-frequency signal at a given intensity feels harsher and fatigues faster than a modulated one, which is why we run PDM underneath the current across 361 frequency points rather than holding one frequency.
Waveform, pulse shape and electrode geometry all change how a given current feels, which is why two devices at the same milliamp figure are not interchangeable.
None of that shows up in a strength ranking, and all of it decides whether you are still using the device in week ten.
Better questions than which is strongest
What is the output and at what load, so the figure can be compared with anything else.
What is the pulse width, since charge rather than current is what tissue responds to.
Does the device cross the motor threshold at all, because that decides whether muscle work is on the table or only skin-level effects.
What is the clearance number, which takes two minutes to check and we have written out how to do it.
And, least technically but most usefully: will you still be using it in three months.
