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.

Forehead and frown lines are carved by repeated muscle contraction, so stimulating those same muscles is the wrong direction, and toxin is the treatment that matches the cause.
This article sets out what to check before you start, such as:
- which muscles make which line
- why toning works against you above the eyebrows
- the difference between a dynamic and a static line
- what the device is still worth doing on the forehead
- when to stop and see an injector
and many more!
This is the one region where we tell people to use the device less rather than more.
Key Points:
Horizontal forehead lines come from the frontalis lifting the brows, and vertical frown lines between the brows come from the corrugator and procerus pulling them together.
Those muscles are not weak; they are doing too much, which is why the standard treatment relaxes them rather than strengthening them.
A dynamic line appears only when you move and a static line is visible at rest, and the second one reflects skin damage rather than muscle position.
Botulinum toxin reduces the contraction that creates the line, and no home device replicates that.
The forehead is still worth including in a session at a low level for the skin and circulation side, not for toning.
Which muscle makes which line
The frontalis is a broad flat sheet across the forehead whose only job is to raise the eyebrows, and every time it fires the skin above it creases horizontally.
The corrugator supercilii pulls the brows together and down, creating the vertical lines between them that people call elevens.
The procerus sits over the bridge of the nose and pulls the inner brow down, adding the horizontal crease there.
Decades of those contractions fold the skin in the same places until the fold stays when the muscle relaxes.
Why toning is the wrong direction
Everywhere else on the face, the argument for stimulation is that better muscle tone supports the tissue above it.
On the forehead the muscle is not failing to support anything; it is actively creating the crease every time it contracts.
Adding contractions to a muscle whose contractions carved the line is working against the result you want.
Ward and colleagues in 2009 set out the thresholds separating sub-sensory, sensory and motor stimulation, and the forehead is the one region where staying below the motor threshold is deliberately the point.
Dynamic and static lines
Raise your eyebrows and look at the lines that appear, then relax completely and look again.
Lines that vanish when you relax are dynamic, caused purely by movement, and they respond to anything that reduces the movement.
Lines still visible at rest are static, which means the skin itself has been folded often enough to hold the crease, and that is a collagen and elastin problem.
Static lines need skin treatment, meaning retinoids, resurfacing or filler, rather than anything to do with muscle.
What the device is still worth doing here
Keep the forehead in the session at a low level, below where you can feel a pull, for the circulation and conductive serum delivery rather than for toning.
Avoid the area between the brows entirely, since that is where the corrugator sits and where any contraction is counterproductive.
Keep the level well below your cheek setting, because the temporalis sits at the sides and overstimulating it is the most common cause of a post-session headache, covered in our article on headaches.
If the forehead is where you feel the session most strongly, your level is too high for that region.
What actually treats these lines
Botulinum toxin reduces the contraction and is the treatment matched to the cause, which is why it has dominated this specific indication for twenty-five years.
Retinoids and resurfacing address the static component by improving the skin that holds the crease.
Daily sunscreen prevents more forehead line formation than anything reverses it, which is unglamorous and true.
Filler is used sparingly in deep static frown lines and is a technical area where the practitioner matters a great deal.
Where that leaves the device
Buy a device for the lower two thirds of the face, where the toning argument actually holds, and treat the forehead as a region you pass over gently.
If forehead and frown lines are your main concern, an injector appointment will do more in twenty minutes than a device does in a year, and we would rather say so.
If you already have toxin in the area, timing for device use is set by your injector, as we cover in our article on injectable timing.
