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 a steady direct current used to push charged ingredients into the skin, which is a delivery technology rather than a muscle one.
This article sets out what to check before you start, such as:
- what galvanic current actually is
- how it differs from microcurrent and EMS
- what iontophoresis means and why it matters
- where the deep cleansing claims overreach
- what we have and have not measured ourselves
and many more!
Galvanic is genuinely useful for delivery and has nothing to do with lifting, despite how it is often sold.
Key Points:
Galvanic current is direct current, meaning it flows steadily in one direction, unlike the pulsed currents used for muscle work.
Its established mechanism is iontophoresis, using like charges repelling to push a charged molecule through the skin barrier.
Microcurrent and EMS are pulsed and aimed at cells and muscle; galvanic is continuous and aimed at delivery.
The deep cleansing claim, where reversed polarity supposedly draws impurities out of pores, has far weaker support than the delivery claim.
We carry iontophoresis and infusion on all five models and we have never measured ingredient penetration on our own devices.
What galvanic current is
Galvanic current is direct current, a steady flow in one direction, named after Luigi Galvani and in use in skin treatment since the nineteenth century.
Unlike the pulsed currents used for muscle stimulation, it does not switch on and off, which is why it behaves so differently on skin.
Because it flows continuously, it can carry charged particles along with it, and that is the entire basis of its use in skincare.
It is the oldest electrical technology in this field and the one whose mechanism is best understood.
How it differs from microcurrent and EMS
Microcurrent is pulsed and runs in the microamp range, aimed at cellular activity rather than at visible muscle contraction.
EMS is pulsed at higher output and is aimed squarely at making muscle contract, which is why you can see it working.
Galvanic is continuous rather than pulsed and is aimed at neither; it is a transport mechanism.
Selling galvanic as a lifting technology confuses a delivery tool with a toning one, and that confusion is common in this category. Our side by side comparison is in our article on the two.
Iontophoresis, the mechanism that holds up
Like charges repel. Put a negatively charged molecule under a negatively charged electrode and the molecule is pushed away from the electrode and into the skin.
That is iontophoresis, and it works only for molecules that carry a charge, which rules out a great many skincare ingredients.
Prausnitz and colleagues in 1993 demonstrated that applied electrical fields can create transient pathways through the outer skin layer, which is the related mechanism known as electroporation.
Zhang and colleagues in 1999 examined how electrical approaches affect delivery of larger molecules through skin, and the consistent finding across this literature is that charge, size and formulation decide whether anything moves.
Where the claims overreach
The deep cleansing claim says that running the current in reverse polarity draws sebum and impurities out of pores, and it is used widely in salon marketing.
The evidence for pulling material out is far weaker than the evidence for pushing material in, and the two are presented as equally established.
Detox is used freely in this corner of the market and has no defined meaning in skin science.
We would rather describe galvanic as a delivery technology with a known mechanism and leave the rest alone.
What a galvanic pass feels like
A mild metallic taste if the current passes near the jaw, which is harmless and unrelated to the skin effect.
A faint prickling or warmth under the electrode, quite different from the pulsing of a muscle setting.
Nothing dramatic and nothing visible, which is why people often assume it is not working.
The sensation depends heavily on the conductive medium, and a drying layer produces the sharp spike covered in our article on sharp sensations.
What we carry and what we have not measured
All five of our models run iontophoresis and an Infuse pass alongside nanocurrent, microcurrent, EMS and the rest of the nine technologies on one dial.
We cite the delivery science above because it is the honest basis for the claim, and we have never measured ingredient penetration on a PureLift device.
That is a real gap in our own evidence and we would rather state it than imply the published mechanism is the same as a measured result on our hardware.
What each technology on the dial does, and what the rest of the market carries, is in our category overview.
This article 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.
