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.

If your jawline has softened because the muscle underneath has slackened, a device that contracts muscle can help; if it has softened because of skin quality or fat redistribution, it will not.
This article covers what actually decides the answer, such as:
- the three separate causes of a softening jawline
- how to work out which one you are dealing with
- why microcurrent alone rarely changes a jawline
- what the research measured, and where on the face
- what no device at any price will do
and many more!
The honest version of this question starts with your face rather than with a product list.
Key Points:
Three causes: platysma and muscle laxity, skin laxity, and fat pad redistribution, and most people over forty have a mix.
Only the first responds to electrical stimulation, and only to current strong enough to contract muscle.
Consumer microcurrent devices publish 200 to 680 microamps, which is below the level at which a muscle contracts.
The research on muscle thickness measured the cheek rather than the jaw, so the jawline case is an inference from mechanism rather than a direct measurement.
Significant skin laxity or fat redistribution is a surgical or procedural question, not a device question.
Three causes that look identical in a mirror
The first is muscle. The platysma runs from the jaw down across the front of the neck, and the muscles around the mouth and jaw lose tone with age like any other. When they slacken, the soft tissue they support sits lower.
The second is skin. Collagen and elastin decline, and skin that has lost recoil drapes rather than holds, which softens the line independently of what the muscle is doing.
The third is fat. The facial fat pads sit in compartments, and with age they lose volume and shift downward, so fullness that used to sit high in the cheek ends up along the jaw.
Most people over forty have some of all three, and the mix decides what will help. A device that addresses muscle will do nothing for fat redistribution, and no amount of consistency changes that.
Working out which you have
Lie on your back and look in a hand mirror. If the jawline looks substantially better lying down, a good part of what you are seeing is soft tissue position rather than skin quality, which is the muscle and fat category.
Pinch the skin on your cheek gently and let go. If it feels thin and settles slowly, skin quality is a significant contributor, and radiofrequency or light-based treatment addresses that more directly than current does.
Compare a photograph from ten years ago at the same angle. Fat redistribution usually shows as fullness moving downward rather than the whole face deflating.
None of this is a diagnosis, and if the change has been rapid or is one-sided, that is a reason to see a doctor rather than to buy a device.
Why microcurrent alone rarely does it
Ward and colleagues described the thresholds separating sub-sensory, sensory and motor current, and a muscle only shortens above the motor threshold.
Published consumer microcurrent figures run from about 200 microamps at the low end to 680 at the top, all below that threshold, and several of those manufacturers say so in their own materials.
So a microcurrent device can improve how the skin looks and can produce a same-day fluid effect along the jaw, both of which are real, and it is not asking the platysma to do anything.
If a jawline is what you are buying for, the output figure and whether it crosses into the milliamp range is the specification that actually matters. The published figures for 33 devices set out where each one sits.
What the research actually measured
Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness in 108 women across twelve weeks of motor-level stimulation, using ultrasound.
The measurement was taken at the cheek rather than along the jaw, which matters and is usually left out when the study is quoted in jawline marketing, ours included until now.
The mechanism generalises reasonably, since muscle responds to work wherever it sits, and a direct jawline measurement would be better evidence than an inference.
We would rather state that limitation plainly than imply the study measured something it did not.
What helps, honestly
For the muscle contribution: a device that crosses the motor threshold, used three to five times a week for twelve weeks, working along the jaw from chin toward the ear rather than across it.
For the skin contribution: radiofrequency, light-based treatment, retinoids and sun protection, none of which we make, and we have written about the devices that do.
For the fat contribution: very little at home, and this is where surgical and injectable options genuinely outperform anything in a bathroom.
For all three: weight stability, sleep and sun protection do more than most people want to hear.
What no device will do
Remove a significant jowl that is primarily fat redistribution.
Tighten skin that has lost substantial elasticity, which is a procedural question.
Change bone structure, which sets the jawline you are working with in the first place.
Produce a result in two weeks, whatever a photograph taken minutes after a session suggests. Our piece on reading those photographs explains what you are actually looking at.
