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.

Every microcurrent device needs a wet conductive layer, and only some of them need that layer to come from the brand that sold you the device.
This article covers what actually decides the answer, such as:
- which brands require their own gel and which merely suggest it
- what a conductive layer has to do physically
- what each named gel costs, by size
- the ingredients that stop a product conducting
- when spending on a branded gel is genuinely worth it
and many more!
If your device takes any water-based serum, the bottle on your shelf is very likely fine.
Key Points:
A conductive layer must be water-based and stay wet for the session, which is a physical requirement rather than a brand one.
NuFACE's FDA file lists a conductive gel primer as a special requirement, and FOREO states BEAR 2 must be used with a conductive serum.
Skin Gym says gel is required, Solawave sells its activating serum separately at $38, and 7E supplies gel with the device.
PureLift devices are specified to work with any water-based serum you already own.
Prices run from $15.99 to $100 a bottle, and no brand publishes how many sessions a bottle delivers.
What the layer is actually for
Current travels through water and the salts dissolved in it, so the layer between the probe and your skin exists to carry the current evenly and to let the probe glide.
A dry or patchy layer concentrates the current into whatever small area still conducts, which is felt as a sting rather than a broad pull.
That is the whole of the job, and it is why a plain hydrating serum can do it as well as a branded gel in most cases.
We have written separately on how to test the serum you already own, which takes about two minutes.
Which devices require their own
NuFACE is the clearest case, since its FDA submission for the MINI+ lists a conductive gel primer under special requirements and the gel carries its own clearance.
FOREO states that BEAR 2 must be used with a conductive serum, and the device is designed around the brand's bottle.
Skin Gym's own FAQ says a conductive gel is required for proper conductivity and comfort.
Solawave describes its activating serum as what conducts the current and gives the wand its glide, then sells it separately at $38.
Droplette is the extreme case in this market: its own FAQ says the device is engineered to work exclusively with its capsules, so there is no choice at all.
Which devices leave it to you
PureLift devices are specified to work with any water-based serum you already own, and our Activator Serum is one option rather than a requirement.
7E Wellness supplies ReStore gel with its devices and states on its own 16 oz listing that the gel works with all microcurrent devices, which is a fair position.
Several radiofrequency devices need a slider or couplant gel for heat transfer rather than conduction, which is a genuine technical requirement rather than a commercial one.
Where you have the choice, the saving over two years is real, and we have set out what every branded gel costs in full.
What to look for if you are choosing
Water or aqua as the first ingredient, which is the single most reliable signal.
Humectants such as glycerin, hyaluronic acid, sodium hyaluronate, panthenol or aloe, all of which hold water at the surface.
Enough slip that the probe glides without dragging, since dragging makes people press harder than they should.
Avoid facial oils, balms, squalane-heavy formulas and anything with dimethicone or cyclopentasiloxane high in the list, because a barrier is the opposite of a conductor.
Alcohol-heavy toners conduct while wet and evaporate too fast to last a session.
When a branded gel is worth buying
When the manufacturer requires it, because using something else may void a warranty even where the physics would be fine.
When you have sensitive skin and have already found a formula that suits you, in which case continuity is worth more than the saving.
When the gel doubles as a treatment you would buy anyway, which several of them do.
What is not a good reason is a claim that the gel conducts better, since no brand publishes a conductivity figure for its own bottle.
How much to use
More than feels natural for skincare, because you are laying down a working layer rather than applying a treatment.
Skin should look visibly wet for the whole of a three-minute pass, and reapplying between sides is normal.
A facial mist over the top extends a layer that would otherwise dry.
If a session starts to feel sharp, add serum before you reach for the level control.
This comparison 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.
Prices and product requirements checked on 21 September 2026 against each brand's own shop and its FDA filing where one exists.
