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.

No. Microcurrent runs in millionths of an amp and works at cell level, while EMS runs in thousandths and contracts the muscle, and the two are separated by roughly a thousandfold difference in current.
This article explains what is actually happening, such as:
- the literal difference between a microamp and a milliamp
- where the motor threshold sits and what crossing it changes
- why brands use the two words loosely
- what each one is genuinely good for
- how to tell which one you are buying
and many more!
Both are legitimate; using the words interchangeably is what causes the trouble.
Key Points:
A microamp is a millionth of an amp and a milliamp is a thousandth, so one milliamp is a thousand microamps.
Microcurrent devices publish 200 to 680 microamps, which is below the level at which a facial muscle contracts.
EMS devices operate in the milliamp range and produce a contraction you can see in the mirror.
Several microcurrent manufacturers state plainly that their current cannot contract a muscle, which is the clearest confirmation available.
A device that names a mode EMS without publishing an output figure has told you nothing about which side of the line it sits on.
The literal difference
An amp measures the flow of electrical charge. A milliamp is one thousandth of an amp and a microamp is one millionth, so a thousand microamps make a single milliamp.
A microcurrent device publishing 500 microamps is delivering half of one milliamp. A facial EMS device publishing 7 milliamps is delivering fourteen times that, and the gap between a typical microcurrent device and a typical facial EMS device is roughly an order of magnitude or more.
That difference is not a matter of degree the way a brighter light is brighter. It is the difference between staying below a biological threshold and crossing it.
The threshold that separates them
Ward and colleagues described the three thresholds in electrical stimulation: sub-sensory, where you feel nothing; sensory, where you feel a tingle; and motor, where the nerve supplying the muscle depolarises and the muscle contracts.
Microcurrent by definition sits in the first two. EMS is defined by reaching the third.
That is why 7E Wellness states in its own FAQ that true microcurrent is sub-sensory and cannot cause a physical or visual manipulation of the muscle, and why Bio-Therapeutic describes its own output as imperceptible. Both are accurately describing their own products.
When a muscle contracts you can see it. That visibility is the simplest test any buyer can apply.
Why the words get mixed
Microcurrent is the term the market searches for, so it has commercial value regardless of what a device does.
EMS sounds more serious, so it has marketing value for devices that do not reach it.
The result is brands using both words on the same page, describing muscle toning while publishing figures that could not contract anything, which is the single most common confusion in this category.
Medicube's Age-R line lists an EMS mode and publishes no output figure for it, which means a buyer cannot tell which side of the threshold that mode sits on. That is a common position rather than an unusual one.
What each one is good for
Microcurrent: skin-level effects, texture, a fresher look, and the same-day fluid movement that follows any session. Real, modest and well suited to a preventative routine.
EMS: the muscle layer that holds the lower face up, which is what changes when a face loses contour rather than surface quality.
Kwak and colleagues ran both on one person, microcurrent on one side and stronger stimulation on the other, and found the microcurrent side improved eye-wrinkle volume and dermal density while the other side improved lifting measures.
That study is the cleanest demonstration that these are complementary rather than competing, and that neither replaces the other.
How to tell which you are buying
Ask for the output figure and the load it was measured at. A figure in hundreds of microamps is microcurrent; a figure in milliamps at a stated load is EMS territory.
Ask whether you should expect to see the muscle move. A manufacturer that says no is describing microcurrent, whatever the mode is called.
Check the FDA indications, which for both categories usually say cosmetic facial stimulation and will not settle the question, so the output figure is what matters.
The published figures for 33 devices sort every device we track into one band or the other.
Where our devices sit
PureLift runs both on one dial, which is the reason this distinction matters to us more than most: levels 1 and 2 are nanocurrent and microcurrent, and from level 3 the current crosses into the muscle band.
We publish 7 mA at 500 ohms for Face and Pro, 7.7 mA for Pro Edition and 9 mA for Pro Plus and GLOW, with a 4 microsecond pulse width.
The older comparison written from the EMS side is here, and covers the same ground for readers who arrive from that direction.
