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 is not vibration; a microcurrent device passes a very low electrical current through the skin to the facial muscles, while a sonic device simply shakes against the skin, and many devices that buzz in your hand have no microcurrent at all.
This guide clears up the confusion, such as:
- why microcurrent usually feels like nothing
- what sonic pulsation actually does
- devices that combine both
- how to check whether your device has real microcurrent
- which one works on a lifted look
and many more!
We make microcurrent devices, and we get this question from buyers who expected to feel a buzz and felt nothing.
Key Points:
Microcurrent is an electrical current, usually so low that you feel a light tingle or nothing.
Sonic devices use fast mechanical pulsations, which you feel clearly as a buzz or massage.
Vibration can feel pleasant and help with cleansing or massage, but it does not deliver current to the muscles.
Some devices combine both, such as FOREO BEAR 2 with microcurrent plus T-Sonic pulsations, and Medicube with sonic vibration alongside its electrical modes.
If a device only vibrates and needs no conductive gel, it is almost certainly not a microcurrent device.
Why people mix them up
Most people expect a beauty device to feel like it is doing something. Microcurrent often does not, because the current is measured in millionths of an amp and sits below or just at the level you can sense. Sonic devices are the opposite, with a strong, obvious buzz.
So when a buyer turns on a microcurrent device and feels nothing, they wonder if it works, and when they turn on a vibrating wand they assume it must be microcurrent. Neither assumption is safe. How microcurrent should feel is explained in our article on what microcurrent feels like.
What sonic pulsation does
A sonic device has a small motor that makes the head oscillate many times a second. Against the skin it feels like a fast massage, and in cleansing brushes it helps loosen makeup and oil.
That movement stays at the surface. It can feel relaxing and may help skin look fresher for a short while, but it does not send any current to the muscles, so it does not tone them.
What microcurrent does
A microcurrent device sends a low electrical current through a layer of conductive gel into the facial muscles. With regular sessions, that gives a firmer, more lifted look along the jaw, cheeks and brows.
A randomized controlled trial by Kavanagh and colleagues, published in 2012, measured the effect of facial electrical stimulation after twelve weeks of regular use. A full explanation is in our article on what a microcurrent device is.
Side by side
| Sonic vibration | Microcurrent | |
|---|---|---|
| Energy | Mechanical movement | Low electrical current |
| Feel | A clear buzz or massage | A light tingle or nothing |
| Needs conductive gel | No | Yes |
| Works on | Skin surface | Facial muscle tone |
| Typical use | Cleansing, massage | A firmer, lifted look |
Devices that combine both
Some devices put both technologies in one head. FOREO BEAR 2 pairs microcurrent with T-Sonic pulsations, and Medicube lists sonic vibration on its Booster Pro alongside electrical modes. In these devices the vibration is a comfort and massage feature, and the microcurrent mode is the part aimed at muscle tone.
Details are in our FOREO BEAR 2 review and our Medicube Booster Pro modes article.
How to check what your device really has
Look for the word microcurrent or a current figure in microamps or milliamps on the box or manual, not just words like lifting or toning.
Check whether the brand asks you to use a conductive gel. Microcurrent needs one, vibration alone does not.
Look for an FDA clearance for the specific device. Our guide to checking is in our FDA clearance guide, and the list of brands that really carry microcurrent is in our article on which brands have microcurrent.
Our devices run nanocurrent at level 1, microcurrent at level 2 and EMS from level 3 to 10, plus an Infuse pass, on one dial, with a ten minute session and no more than three minutes per side of the face, and they work with any water-based conductive serum.
Do not use any facial current device if you have a pacemaker or other implanted electronic device, if you are pregnant or if you have epilepsy, and skip broken or irritated skin. The full list is in our safety article.
Frequently asked questions
Is microcurrent just vibration
No. Microcurrent is a low electrical current; vibration is mechanical movement.
Why can't I feel my microcurrent device
Microcurrent is very low and often sits below what you can sense. A light tingle or nothing is normal.
Does sonic vibration lift the face
Sonic vibration works at the surface as a massage and does not tone the facial muscles.
Do I need gel for a sonic device
Usually not, but you do need a conductive gel for microcurrent.
Which devices combine sonic and microcurrent
FOREO BEAR 2 pairs microcurrent with T-Sonic pulsations, and Medicube adds sonic vibration to its electrical modes.
