El Prof. Dr. med. Ivo Buschmann es Catedrático de Angiología en la Medizinische Hochschule Brandenburg Theodor Fontane (MHB) y Director Clínico de la Clínica Universitaria de Angiología en el Hospital Universitario de Brandeburgo. Completó su formación médica en la Universidad de Hamburgo, fue becario de la Sociedad Max-Planck en el Instituto Max-Planck de Investigación Cardiaca y Pulmonar, y ocupó cargos de consultor senior en la Charité Universitätsmedizin Berlin Campus Virchow antes de ser nombrado Catedrático en la MHB en 2016.
El Prof. Buschmann es una de las principales autoridades europeas en arteriogénesis — el crecimiento y remodelación de los vasos sanguíneos impulsados por el flujo — con más de 150 publicaciones revisadas por pares y varias patentes en EE. UU. y la UE sobre dispositivos que estimulan el crecimiento de vasos colaterales mediante terapia controlada de tasa de cizalladura. Su investigación conecta la estimulación mecánica y eléctrica con la adaptación vascular, la microcirculación y la perfusión tisular.
Las contribuciones del Prof. Buschmann aportan a los lectores de PureLift LAB una perspectiva de biología vascular que complementa nuestra autoría clínica, de fisioterapia y de anatomía quirúrgica existente — explicando cómo la estimulación EMS activa no solo los músculos faciales sino también la microcirculación que los abastece, y por qué la administración inteligente es tan importante a nivel del flujo sanguíneo como en la contracción muscular.

Galvanic current is used to move product into the skin and to loosen sebum, while microcurrent is aimed at the skin's own cells, and several devices quietly deliver the first while calling it the second.
This article explains what is actually happening, such as:
- what galvanic current does in a facial
- the two directions galvanic is run in, and why
- how iontophoresis fits into the picture
- why some devices blur the two terms
- which one you are actually buying
and many more!
Solawave, to its credit, describes its own current as iontophoretic rather than dressing it up as something else.
Key Points:
Galvanic current is direct current, used in facials to move charged ingredients into the skin and, in the other polarity, to loosen sebum before extraction.
Iontophoresis is the name for the ingredient-delivery use of galvanic current, and its effect on penetration has been measured.
Microcurrent is also a low current, and its claimed effects are on the skin's own cells rather than on product delivery.
Several consumer devices deliver what is functionally galvanic current while marketing it under the microcurrent name.
Neither galvanic nor microcurrent contracts a facial muscle.
What galvanic current does
Galvanic current is direct current, flowing steadily in one direction rather than pulsing, and it has been used in facials for over a century.
Run in one polarity it repels charged ingredients away from the electrode and into the skin, which is the basis of iontophoresis and of every product-penetration claim in this field.
Run in the other it is used in what estheticians call desincrustation, softening and loosening sebum in the follicle before extraction, which is why it appears on treatment menus for congested skin.
So galvanic is fundamentally about moving things: ingredients in, or sebum loose. It is not aimed at changing the skin itself.
What the evidence says about delivery
Zhang and colleagues measured the increase in vitamin C penetration produced by iontophoresis, which is the kind of quantified result this category usually lacks.
Electroporation is a related but distinct approach, using brief pulses to open temporary routes through the outer skin barrier, established by Prausnitz and colleagues in 1993.
Both are delivery technologies rather than treatments in themselves, which means their value depends entirely on what you are delivering.
A galvanic device with a poor serum is doing very little, and that is a genuine limitation rather than a quibble.
Where microcurrent differs
Microcurrent is usually pulsed rather than steady, sits in the hundreds of microamps, and is aimed at the skin's own cells rather than at moving a product through the barrier.
The claims are about texture, tone and appearance over repeated sessions, not about penetration.
There is genuine overlap in the sense that both are low currents applied to the face, and the honest distinction is intent and waveform rather than a hard physical boundary.
Neither contracts a muscle, which is the one thing both categories agree on when pressed.
Why the terms get blurred
Microcurrent is the term with search volume and cultural cachet, so it gets applied to devices whose function is closer to galvanic.
Solawave is the honourable exception worth naming: it publishes about 200 microamps at 10.5 Hz and describes its own current as the kind used in iontophoresis to help topical products absorb. That is an accurate description of what a galvanic-style current does.
Other brands describe the same function in lifting and toning language, which is where a buyer ends up disappointed.
If a device's main claim is that your serum works better, you are looking at a delivery device whatever the box says.
Which one you want
If your goal is getting more out of the serums you already own, a delivery-focused device is the honest purchase, and the results depend on the serum as much as the device.
If your goal is the skin's own texture and tone, microcurrent is aimed at that.
If your goal is contour, neither, and you want the muscle band instead.
Our own devices run both delivery technologies in the Infuse pass, electroporation-based Infusion and iontophoresis together, alongside the current bands, which is why we treat them as separate jobs rather than as one blurred claim.
A note on our own gap
We cite Zhang and Prausnitz for the delivery science, and neither study was run on a PureLift.
We have not measured how much more of an ingredient our Infuse pass delivers into skin, and until we do, our position on delivery rests on mechanism rather than on our own data.
That is the same shape of gap we point at in other brands, and we would rather write it down than hope nobody asks.
