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.

Radiofrequency heats the dermis to trigger a collagen response over weeks, and microcurrent passes a current that works at cell level without heating anything, so they address different complaints.
This article compares the two on what decides the result you actually see, such as:
- what each one physically does to tissue
- why 42 degrees is the number that matters in radiofrequency
- what the published figures look like on each side
- session length, course length and cost compared
- which to buy for which complaint, and when to buy both
and many more!
We make one of these two technologies and not the other, which shapes what follows and is stated plainly throughout.
Key Points:
Radiofrequency passes current through tissue, meets resistance, and produces heat, with home devices capping at about 42 to 43 degrees Celsius.
Collagen denatures and contracts at roughly 60 to 65 degrees, so home radiofrequency is a slow remodelling stimulus rather than an immediate tightening.
Microcurrent passes a far smaller current that does not heat tissue, working at cell level instead.
Above the motor threshold, in the milliamp range, current contracts muscle, which is a third thing neither of the above describes.
NEWA's De Novo publishes 1 MHz, up to 10 W and a 42 degree cutoff, the clearest disclosure in the home radiofrequency category.
What radiofrequency actually does
Radiofrequency current passes through tissue, the tissue resists it, and that resistance produces heat. The target is the collagen in the dermis.
Home devices cap the temperature with a thermal sensor, typically at 42 to 43 degrees Celsius. Collagen denatures and contracts at roughly 60 to 65 degrees, which is why a home device is not shortening collagen on the spot.
What it is doing instead is applying a controlled sub-injury heat stress that prompts fibroblasts to produce new collagen over the following weeks, which is why these treatments run in courses and report results at eight to twelve weeks.
The FDA product code for these devices describes radiofrequency coagulation for wrinkle reduction, which tells you plainly what regulators consider the mechanism to be.
What microcurrent does
Microcurrent runs in the hundreds of microamps, far too low to heat tissue meaningfully or to depolarise a motor nerve.
Its claimed effects are cellular, and the evidence is real but modest. Saniee and colleagues examined microcurrent effects on facial skin, and the reported benefits run to texture and appearance.
So microcurrent and radiofrequency are not competing to do the same job by different routes. Radiofrequency is trying to change the structural protein content of the dermis; microcurrent is acting on cells without heat.
Neither of the two contracts a muscle, which is worth stating because both categories borrow lifting language freely.
The third thing, which is neither
Above roughly one milliamp with an appropriate pulse, current crosses the motor threshold and the muscle contracts.
Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness across 108 women over twelve weeks at that level, which is a change in the muscle rather than in the skin or its collagen.
That is our category, and it is a different answer again from either of the two in this comparison.
If you find yourself deciding between radiofrequency and microcurrent because your face has changed shape, the honest answer is that neither is aimed at your problem.
What each side publishes
On the radiofrequency side, NEWA holds a De Novo authorisation whose grant publishes 1 MHz, up to 10 W and a thermal cutoff at 42 degrees. That is the most complete disclosure in the home category and deserves credit.
TriPollar publishes no frequency, wattage or temperature cap for its home device, and Silk'n publishes only a 43 degree cap with no frequency or power.
On the microcurrent side, FOREO publishes 680 microamps, ZIIP 309, Therabody 500 and 7E 350 at a stated 500 ohm load, while NuFACE's figures appear only in filings.
Across both categories, most brands publish a feature list rather than a specification, which we have set out in the full table of 33 devices.
Practical differences
Radiofrequency sessions run longer, typically nine to fifteen minutes, and the protocols are demanding: NEWA's cleared protocol is four minutes across six facial areas, five times weekly for four weeks.
Radiofrequency needs a couplant gel for heat transfer, which is a genuine technical requirement rather than a commercial one, at $15.99 to $53 a bottle depending on brand.
Radiofrequency also carries the longer contraindication list, since it generates real heat: implants, fillers, pacemakers, recent procedures and heat-sensitive conditions all appear.
Microcurrent sessions are shorter, the conductor requirement is often avoidable, and the contraindication list is shorter though still real.
Which to buy
Pinch the skin on your cheek. If it feels thin and settles slowly, your complaint is skin quality and radiofrequency addresses it more directly than microcurrent does.
If the surface is holding but the shape has changed, that is contour, and neither of these two is the answer; muscle-level work is.
If your complaint is dullness, texture and looking tired, microcurrent is a reasonable and cheaper purchase.
They stack without conflict. If you own both, run them on separate days rather than stacking heat and current in one session, and follow each manufacturer's own guidance on spacing.
We do not make a radiofrequency device and have no plans to, so if that is what your skin needs, buy one from someone else. We have written about the devices we do not compete with for exactly this reason.
