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 published study has measured facial fat before and after a course of microcurrent or facial EMS, so nobody can honestly tell you it causes fat loss or that it does not.
This article sets out what to check before you start, such as:
- what the facial stimulation studies actually measured
- why muscle thickness and fat are different questions
- why some people think their face looks hollower
- what genuinely reduces facial fat
- what we would need to measure to answer this properly
and many more!
We would rather tell you this has not been studied than give you a confident answer nobody has earned.
Key Points:
The facial stimulation trials measured muscle thickness, skin parameters and observer ratings, not adipose tissue.
Electrical stimulation at these levels has no established mechanism for breaking down fat; the technologies marketed for fat reduction work by cooling, heating or injected agents.
Facial hollowing over time is overwhelmingly explained by age-related fat pad changes, bone remodelling and weight loss, all of which proceed regardless of any device.
If your face is visibly slimming, look at your weight, your medication and your health before you look at a facial device.
Anyone claiming a facial toning device removes fat, or guaranteeing it cannot, is going beyond the evidence.
What the studies actually measured
Kavanagh and colleagues in 2012 ran the most cited facial stimulation trial, following 108 women over twelve weeks and reporting an 18.6 percent increase in cheek muscle thickness measured by ultrasound at the cheek.
That measurement was of muscle, and the study did not report adipose thickness as a separate outcome.
Other trials in this space measured skin elasticity, wrinkle depth, dermal density and blinded observer ratings.
So across the whole body of facial stimulation research, the question of what happens to facial fat has simply not been asked.
Why fat and muscle are different questions
Muscle responds to repeated contraction by adapting, which is the whole basis of the facial stimulation claim, and adipose tissue does not work that way.
The technologies marketed for fat reduction operate by controlled cooling, by heating adipose tissue to a damaging temperature, or by injecting an agent that disrupts fat cell membranes.
None of those mechanisms exists in a device delivering microamps or single-figure milliamps through the skin.
The absence of a mechanism is not proof of absence, which is precisely why we are declining to make a claim in either direction.
Why people think they see hollowing
Faces lose volume with age, and the loss is well described: the superficial and deep fat pads shrink and shift, the bone beneath remodels, and the overlying skin has less to sit on.
Anyone who starts a daily facial routine in their forties or fifties is also getting older during the months they are using it, and the two changes overlap.
Weight change is the other common explanation, and a few kilograms shows in the face before it shows anywhere people notice.
Medication that affects appetite or weight, including the GLP-1 drugs now in wide use, produces facial volume loss that has nothing whatever to do with a device.
What we would need to answer this
Ultrasound or MRI measurement of the facial fat pads at baseline and after a defined course, on the treated and untreated sides of the same face, with weight controlled.
A split-face design would handle most of the confounding, because each participant serves as their own control for age and weight.
That study has not been run by us or by anyone else in this category, as far as we can find.
It is a real gap, and this page exists partly to say so rather than to fill it with reassurance.
If your face is genuinely slimming
Check your weight first, because unintentional weight loss is the most common explanation and the most important one to act on.
Consider recent medication changes, particularly anything affecting appetite.
Unintentional weight loss, especially with other symptoms, is a reason to see a doctor rather than to adjust your skincare routine.
If you want facial volume restored, that is a filler or fat grafting conversation with a qualified practitioner, and no home device addresses it.
What we say about our own devices
We publish what our devices deliver, which is 7 mA at 500 ohms on Face and Pro, 7.7 mA on Pro Edition and 9 mA on Pro Plus and GLOW, with a 4 microsecond pulse width.
We claim cosmetic facial stimulation, which is what our clearances cover, and we have never claimed fat reduction.
We also have not measured facial fat on our own devices, and until someone does, this page will keep saying the question is open.
The broader map of what each technology can and cannot do 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.
