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.

Korean devices such as Medicube's AGE-R range tend to pack many modes and app features into one affordable head, while Japanese makers such as YA-MAN and MTG's ReFa have long specialized in EMS and massage devices, so the best choice depends on whether you want many skincare modes or focused muscle work.
This guide covers what to know before you buy, such as:
- how the Korean and Japanese device markets differ
- the best-known brands from each
- what each typically uses, microcurrent, EMS or massage
- what to check before importing a device
- how a made in Japan device fits in
and many more!
We make PureLift in Japan, so we know this market well and say plainly where other brands do well.
Key Points:
Korean devices are known for many modes in one tool, often combining delivery, microcurrent, EMS, sonic and LED.
Japanese devices have a long history in EMS and massage, from brands such as YA-MAN and ReFa.
Many popular Asian devices use EMS rather than microcurrent, so check what each mode actually is.
Imported devices may lack a US FDA clearance, a US plug or a US warranty, so check before buying.
PureLift is made in Japan under ISO 13485 and every model has its own FDA 510(k) clearance.
Two markets, two philosophies
Korea and Japan are the two biggest sources of beauty devices outside the US, and searchers often lump them together. In practice they have grown up with different priorities.
Korean brands move quickly and favor all-in-one tools, often with an app, many modes and a price that makes trying one easy. Japanese brands have a longer history in salon and home EMS and massage devices, and tend to focus on fewer functions with a strong emphasis on build quality.
Korean devices
The best-known Korean device is the Medicube AGE-R Booster Pro, which lists Booster, Air Shot, MC and Derma Shot modes along with sonic vibration and LED. Independent guides describe Booster as electroporation, MC as microcurrent and Derma Shot as mid-frequency EMS. The newer Booster Pro X2 adds AI, Dual and Mask modes.
Every mode is explained in our Medicube modes article, and the X2 is reviewed in our Booster Pro X2 review. How it compares with a US device is in our Medicube vs NuFACE article.
Japanese devices
YA-MAN is one of Japan's longest-running beauty device makers, and its Medi Lift EMS masks and handheld devices are widely sold. Our comparison is in our PureLift vs YA-MAN Medi Lift article.
MTG's ReFa range is best known for rollers, some with solar panels that the brand says generate a weak microcurrent. What rollers can and cannot do is in our pens, rollers and patches article.
Microcurrent or EMS, check every mode
Many of the most popular Asian devices rely on EMS, which makes muscles visibly contract, rather than microcurrent, which works at a much lower level. Both can tone, but they feel and behave differently, and a device marketed as microcurrent may mostly run EMS.
How the two differ is in our microcurrent vs EMS article, and a randomized controlled trial by Kavanagh and colleagues, published in 2012, measured the effect of facial electrical stimulation after twelve weeks of regular use.
What to check before importing a device
| Check | Why it matters |
|---|---|
| FDA clearance for the exact model | A clearance in Korea or Japan is not a US clearance |
| Voltage and plug | Some Japanese models are built for 100 volts |
| Manual in English | Settings and safety warnings must be clear |
| Warranty in your country | Grey imports may not be covered |
| Gel or serum requirement | Some need a specific branded gel |
Our guide to checking clearances is in our FDA clearance guide.
Where PureLift fits
PureLift is made in Japan under ISO 13485, the quality standard for medical device manufacturing, and every model carries its own FDA 510(k) clearance, from PureLift Face under K190269 to GLOW under K243587. We combine the Japanese focus on muscle work with the multi-technology approach Korean buyers like.
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.
Our range is explained in our PureLift range guide.
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.
