Le Dr Bertica M. Rubio est une médecin certifiée et directrice médicale de la clinique de médecine régénérative anti-âge à Redlands, en Californie. Elle a obtenu son Bachelor of Science à l'Université Loyola Marymount et son Doctorat en médecine à la Dartmouth Medical School (Geisel School of Medicine). Elle a effectué sa résidence en pédiatrie au UC Irvine Medical Center.
Forte de plusieurs décennies d'expérience clinique, le Dr Rubio est spécialisée en médecine de gestion du vieillissement, médecine régénérative, cicatrisation des plaies et thérapies par facteurs de croissance. Sa pratique intègre la science médicale fondée sur des preuves avec des traitements esthétiques et régénératifs avancés, aidant les patients à atteindre une santé optimale et une vitalité juvénile.
Le Dr Rubio est passionnée par l'éducation des patients sur la science derrière les soins de la peau, le rajeunissement du visage et les technologies non invasives comme l'EMS (stimulation électrique musculaire) pour le tonus facial. Ses articles pour PureLift LAB allient connaissances médicales rigoureuses et conseils pratiques pour obtenir des résultats réels et durables.

Daniel Grinberg, MD, FACS, est un oto-rhino-laryngologiste certifié par le conseil et chirurgien de la tête et du cou chez ENT and Allergy Associates à West Nyack, NY. Il a obtenu son diplôme de médecine au Columbia University College of Physicians and Surgeons, a effectué sa résidence en oto-rhino-laryngologie au New York University Medical Center, et est professeur clinique adjoint à la Mount Sinai School of Medicine. Il est membre de l'American College of Surgeons et de l'American Academy of Otolaryngology.
La perspective chirurgicale de la tête et du cou du Dr Grinberg offre aux lecteurs de PureLift LAB une vision clinique élargie — reliant la pratique EMS à domicile à l'anatomie médicale sous-jacente avec la même rigueur scientifique que celle que nous appliquons à chaque spécification d'appareil.

Le Prof. Dr. med. Ivo Buschmann est titulaire de la chaire d'angiologie à la Medizinische Hochschule Brandenburg Theodor Fontane (MHB) et directeur de la clinique universitaire d'angiologie à l'hôpital universitaire de Brandebourg. Il a effectué sa formation médicale à l'Université de Hambourg, a été boursier de la Société Max-Planck à l'Institut Max-Planck de recherche sur le cœur et les poumons, et a occupé des postes de consultant principal à la Charité Universitätsmedizin Berlin Campus Virchow avant d'être nommé titulaire de la chaire à la MHB en 2016.
Le Prof. Buschmann est l'une des principales autorités européennes en arteriogenèse — la croissance et le remodelage des vaisseaux sanguins induits par le flux — avec plus de 150 publications évaluées par des pairs et plusieurs brevets américains et européens sur des dispositifs stimulant la croissance des vaisseaux collatéraux par une thérapie contrôlée du taux de cisaillement. Ses recherches relient la stimulation mécanique et électrique à l'adaptation vasculaire, à la microcirculation et à la perfusion tissulaire.
Les contributions du Prof. Buschmann apportent aux lecteurs de PureLift LAB une perspective en biologie vasculaire qui complète notre expertise clinique, en physiothérapie et en anatomie chirurgicale — expliquant comment la stimulation EMS engage non seulement les muscles faciaux mais aussi la microcirculation qui les alimente, et pourquoi une administration intelligente est aussi importante au niveau du flux sanguin qu'à celui de la contraction musculaire.

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.
