Le Prof. Dr. med. Ivo Buschmann est titulaire de la chaire d'angiologie à la Medizinische Hochschule Brandenburg Theodor Fontane (MHB) et directeur de la clinique universitaire d'angiologie à l'hôpital universitaire de Brandebourg. Il a effectué sa formation médicale à l'Université de Hambourg, a été boursier de la Société Max-Planck à l'Institut Max-Planck de recherche sur le cœur et les poumons, et a occupé des postes de consultant principal à la Charité Universitätsmedizin Berlin Campus Virchow avant d'être nommé titulaire de la chaire à la MHB en 2016.
Le Prof. Buschmann est l'une des principales autorités européennes en arteriogenèse — la croissance et le remodelage des vaisseaux sanguins induits par le flux — avec plus de 150 publications évaluées par des pairs et plusieurs brevets américains et européens sur des dispositifs stimulant la croissance des vaisseaux collatéraux par une thérapie contrôlée du taux de cisaillement. Ses recherches relient la stimulation mécanique et électrique à l'adaptation vasculaire, à la microcirculation et à la perfusion tissulaire.
Les contributions du Prof. Buschmann apportent aux lecteurs de PureLift LAB une perspective en biologie vasculaire qui complète notre expertise clinique, en physiothérapie et en anatomie chirurgicale — expliquant comment la stimulation EMS engage non seulement les muscles faciaux mais aussi la microcirculation qui les alimente, et pourquoi une administration intelligente est aussi importante au niveau du flux sanguin qu'à celui de la contraction musculaire.

Microcurrent itself has no established delivery mechanism, and two related technologies, iontophoresis and electroporation, do, which is why the answer depends on which mode your device is running.
This article sets out what to check before you start, such as:
- the two mechanisms that genuinely move ingredients
- why microcurrent is not one of them
- which ingredients can actually be driven and which cannot
- the measurement nobody in this category has published
- what to pair with a delivery pass and what to avoid
and many more!
We cite the delivery science because it is real, and we have never measured penetration on our own device, which we would rather say than imply.
Key Points:
Iontophoresis uses like charges repelling to push a charged molecule through the skin barrier, and it only works on molecules that carry a charge.
Electroporation uses brief electrical pulses to open transient pathways through the outer skin layer, which can allow larger molecules through.
Microcurrent is a pulsed current aimed at cellular activity and muscle, with no established transport mechanism of its own.
Molecular size, charge and the formulation base decide whether anything moves, which rules out a large share of skincare ingredients.
No brand in this category, ours included, has published measured penetration data on its own device.
Three different technologies, often sold as one
Iontophoresis
Direct current flowing steadily in one direction can carry charged particles along with it.
Place a negatively charged molecule under a negatively charged electrode and it is repelled away from the electrode and into the skin.
That is the entire mechanism, and it has been used clinically for decades, including for delivering local anesthetics and treating excessive sweating.
It only works on molecules that carry a charge, which is the limitation that most marketing omits. The technology itself is covered in our galvanic article.
Electroporation
Short, higher voltage pulses can briefly disrupt the lipid structure of the stratum corneum, creating temporary pathways.
Prausnitz and colleagues in 1993 demonstrated that applied electrical fields create these transient pathways, which is the foundational work in this area.
Because the pathways are physical rather than charge-dependent, larger and uncharged molecules can in principle move through.
Zhang and colleagues in 1999 examined how electrical approaches affect delivery of larger molecules through skin, and the consistent theme across this literature is that size, charge and formulation determine the outcome.
Microcurrent
Microcurrent is pulsed and runs in the microamp range, aimed at cellular activity rather than at transport.
There is no established mechanism by which it drives ingredients through the skin barrier.
When a brand claims its microcurrent device improves absorption, it is usually describing a separate iontophoresis or infusion mode, or it is describing nothing in particular.
What can actually move, and what cannot
Small, water-soluble, charged molecules are the realistic candidates. Vitamin C in certain forms, some peptides and certain minerals fall here.
Hyaluronic acid is instructive. The large molecular weight versions that sit on the surface and hold water are too big to be driven anywhere, while low molecular weight fragments are a different proposition.
Oils, silicones and anything in a heavy emollient base will not move and will not conduct either, so the session itself fails.
Large proteins such as collagen in a serum are far too big to cross intact skin by any of these mechanisms, with or without current, which is worth knowing before paying for a collagen serum to use with a device.
Which bases conduct at all is a separate practical question, covered in our article on testing your own serum.
The measurement nobody publishes
To claim improved absorption honestly you would measure how much of a named ingredient reaches living skin with the device and without it, on human skin, with the same formulation.
That measurement is routine in pharmaceutical development and essentially absent from this consumer category.
We have not done it either. We cite Prausnitz and Zhang for the mechanism and we have never measured ingredient penetration on a PureLift device.
Stating that gap is more useful to you than another paragraph of confident language, and it is the same position we take on ATP in our ATP article.
What to pair with a delivery pass
Reasonable candidates
Hydrating and soothing ingredients that do not depend on low pH, such as glycerin, panthenol and niacinamide at moderate strength.
Peptides, which are a plausible fit on size and charge grounds even though nobody has measured them on a consumer device.
A plain water-based conductive gel, which is the correct base whether or not you care about delivery.
What to keep away
Exfoliating acids, whose whole purpose is a controlled interaction with the outer layer. Driving one deeper is untested and the sting is reliable, covered in our article on acids and vitamin C.
Retinoids, for the same reason and with the same absence of evidence, covered in our retinol article.
Anything with alcohol, fragrance or essential oils, which irritate considerably more under current.
Anything oil or silicone based, which blocks the session entirely.
How to judge an absorption claim
Ask which mode is doing the work. If the answer is microcurrent rather than iontophoresis or electroporation, there is no mechanism behind it.
Ask which ingredient. A claim about delivery in general is not a claim about the serum you own.
Ask whether penetration was measured, and on what. The honest answer across this category is that it was not.
Treat the words infusion and delivery as descriptions of a mode rather than as evidence, including on our own pages.
Our devices run iontophoresis and an Infuse pass alongside nanocurrent, microcurrent and EMS, and the mechanism we rely on is the published one rather than a measurement of our own.
Frequently asked questions
Does microcurrent help serum absorb
Microcurrent itself has no established delivery mechanism. Iontophoresis and electroporation do, and those are separate modes that some multi-technology devices include.
What is the difference between iontophoresis and electroporation
Iontophoresis uses charge repulsion to push charged molecules through skin. Electroporation uses brief pulses to create temporary physical pathways, which can admit larger and uncharged molecules.
Which skincare ingredients work with microcurrent devices
Small, water-soluble, charged molecules are the realistic candidates. Oils, silicones, heavy emollients and very large molecules such as collagen will not move and usually block conduction as well.
Can you drive hyaluronic acid into skin with a device
High molecular weight hyaluronic acid is too large to cross intact skin by these mechanisms. It still works well as a conductive layer because it is water-based.
Has anyone measured how much more product a device delivers
Not in this consumer category, as far as we can find. The mechanisms are published in the pharmaceutical literature; device-specific penetration measurements are not.
