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.

Every microcurrent device needs a wet conductive layer, and only some of them need that layer to come from the brand that sold you the device.
This article covers what actually decides the answer, such as:
- which brands require their own gel and which merely suggest it
- what a conductive layer has to do physically
- what each named gel costs, by size
- the ingredients that stop a product conducting
- when spending on a branded gel is genuinely worth it
and many more!
If your device takes any water-based serum, the bottle on your shelf is very likely fine.
Key Points:
A conductive layer must be water-based and stay wet for the session, which is a physical requirement rather than a brand one.
NuFACE's FDA file lists a conductive gel primer as a special requirement, and FOREO states BEAR 2 must be used with a conductive serum.
Skin Gym says gel is required, Solawave sells its activating serum separately at $38, and 7E supplies gel with the device.
PureLift devices are specified to work with any water-based serum you already own.
Prices run from $15.99 to $100 a bottle, and no brand publishes how many sessions a bottle delivers.
What the layer is actually for
Current travels through water and the salts dissolved in it, so the layer between the probe and your skin exists to carry the current evenly and to let the probe glide.
A dry or patchy layer concentrates the current into whatever small area still conducts, which is felt as a sting rather than a broad pull.
That is the whole of the job, and it is why a plain hydrating serum can do it as well as a branded gel in most cases.
We have written separately on how to test the serum you already own, which takes about two minutes.
Which devices require their own
NuFACE is the clearest case, since its FDA submission for the MINI+ lists a conductive gel primer under special requirements and the gel carries its own clearance.
FOREO states that BEAR 2 must be used with a conductive serum, and the device is designed around the brand's bottle.
Skin Gym's own FAQ says a conductive gel is required for proper conductivity and comfort.
Solawave describes its activating serum as what conducts the current and gives the wand its glide, then sells it separately at $38.
Droplette is the extreme case in this market: its own FAQ says the device is engineered to work exclusively with its capsules, so there is no choice at all.
Which devices leave it to you
PureLift devices are specified to work with any water-based serum you already own, and our Activator Serum is one option rather than a requirement.
7E Wellness supplies ReStore gel with its devices and states on its own 16 oz listing that the gel works with all microcurrent devices, which is a fair position.
Several radiofrequency devices need a slider or couplant gel for heat transfer rather than conduction, which is a genuine technical requirement rather than a commercial one.
Where you have the choice, the saving over two years is real, and we have set out what every branded gel costs in full.
What to look for if you are choosing
Water or aqua as the first ingredient, which is the single most reliable signal.
Humectants such as glycerin, hyaluronic acid, sodium hyaluronate, panthenol or aloe, all of which hold water at the surface.
Enough slip that the probe glides without dragging, since dragging makes people press harder than they should.
Avoid facial oils, balms, squalane-heavy formulas and anything with dimethicone or cyclopentasiloxane high in the list, because a barrier is the opposite of a conductor.
Alcohol-heavy toners conduct while wet and evaporate too fast to last a session.
When a branded gel is worth buying
When the manufacturer requires it, because using something else may void a warranty even where the physics would be fine.
When you have sensitive skin and have already found a formula that suits you, in which case continuity is worth more than the saving.
When the gel doubles as a treatment you would buy anyway, which several of them do.
What is not a good reason is a claim that the gel conducts better, since no brand publishes a conductivity figure for its own bottle.
How much to use
More than feels natural for skincare, because you are laying down a working layer rather than applying a treatment.
Skin should look visibly wet for the whole of a three-minute pass, and reapplying between sides is normal.
A facial mist over the top extends a layer that would otherwise dry.
If a session starts to feel sharp, add serum before you reach for the level control.
This comparison 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.
Prices and product requirements checked on 21 September 2026 against each brand's own shop and its FDA filing where one exists.
