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.

No published study has measured facial fat before and after a course of microcurrent or facial EMS, so nobody can honestly tell you it causes fat loss or that it does not.
This article sets out what to check before you start, such as:
- what the facial stimulation studies actually measured
- why muscle thickness and fat are different questions
- why some people think their face looks hollower
- what genuinely reduces facial fat
- what we would need to measure to answer this properly
and many more!
We would rather tell you this has not been studied than give you a confident answer nobody has earned.
Key Points:
The facial stimulation trials measured muscle thickness, skin parameters and observer ratings, not adipose tissue.
Electrical stimulation at these levels has no established mechanism for breaking down fat; the technologies marketed for fat reduction work by cooling, heating or injected agents.
Facial hollowing over time is overwhelmingly explained by age-related fat pad changes, bone remodelling and weight loss, all of which proceed regardless of any device.
If your face is visibly slimming, look at your weight, your medication and your health before you look at a facial device.
Anyone claiming a facial toning device removes fat, or guaranteeing it cannot, is going beyond the evidence.
What the studies actually measured
Kavanagh and colleagues in 2012 ran the most cited facial stimulation trial, following 108 women over twelve weeks and reporting an 18.6 percent increase in cheek muscle thickness measured by ultrasound at the cheek.
That measurement was of muscle, and the study did not report adipose thickness as a separate outcome.
Other trials in this space measured skin elasticity, wrinkle depth, dermal density and blinded observer ratings.
So across the whole body of facial stimulation research, the question of what happens to facial fat has simply not been asked.
Why fat and muscle are different questions
Muscle responds to repeated contraction by adapting, which is the whole basis of the facial stimulation claim, and adipose tissue does not work that way.
The technologies marketed for fat reduction operate by controlled cooling, by heating adipose tissue to a damaging temperature, or by injecting an agent that disrupts fat cell membranes.
None of those mechanisms exists in a device delivering microamps or single-figure milliamps through the skin.
The absence of a mechanism is not proof of absence, which is precisely why we are declining to make a claim in either direction.
Why people think they see hollowing
Faces lose volume with age, and the loss is well described: the superficial and deep fat pads shrink and shift, the bone beneath remodels, and the overlying skin has less to sit on.
Anyone who starts a daily facial routine in their forties or fifties is also getting older during the months they are using it, and the two changes overlap.
Weight change is the other common explanation, and a few kilograms shows in the face before it shows anywhere people notice.
Medication that affects appetite or weight, including the GLP-1 drugs now in wide use, produces facial volume loss that has nothing whatever to do with a device.
What we would need to answer this
Ultrasound or MRI measurement of the facial fat pads at baseline and after a defined course, on the treated and untreated sides of the same face, with weight controlled.
A split-face design would handle most of the confounding, because each participant serves as their own control for age and weight.
That study has not been run by us or by anyone else in this category, as far as we can find.
It is a real gap, and this page exists partly to say so rather than to fill it with reassurance.
If your face is genuinely slimming
Check your weight first, because unintentional weight loss is the most common explanation and the most important one to act on.
Consider recent medication changes, particularly anything affecting appetite.
Unintentional weight loss, especially with other symptoms, is a reason to see a doctor rather than to adjust your skincare routine.
If you want facial volume restored, that is a filler or fat grafting conversation with a qualified practitioner, and no home device addresses it.
What we say about our own devices
We publish what our devices deliver, which is 7 mA at 500 ohms on Face and Pro, 7.7 mA on Pro Edition and 9 mA on Pro Plus and GLOW, with a 4 microsecond pulse width.
We claim cosmetic facial stimulation, which is what our clearances cover, and we have never claimed fat reduction.
We also have not measured facial fat on our own devices, and until someone does, this page will keep saying the question is open.
The broader map of what each technology can and cannot do is in our category overview.
This article sits inside our full map of the category, where we set out all 33 devices we track, what each one carries and what each brand publishes: Nine Technologies on One Dial, What the Rest of the Market Actually Carries.
