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.

Red light and microcurrent both work at skin level by different routes, neither of them reaches muscle, and choosing between them depends on whether your complaint is texture or contour.
This article compares the two on what decides the result you actually see, such as:
- what each one does at the level of tissue
- what the published evidence supports for each
- coverage, session length and effort compared
- why neither of them changes facial contour
- whether owning both makes sense
and many more!
Neither of these is the right answer if what has changed is the shape of your face rather than its surface.
Key Points:
Red light at around 630 nm is absorbed by skin cells and has been studied for fine lines and texture.
Microcurrent passes a small electrical current through tissue and has measured effects on skin texture and dermal density.
Neither reaches the muscle layer, because light is not current and microcurrent is below the level that contracts muscle.
A mask treats the whole face hands-free; a microcurrent wand treats what you hold it against.
They stack without conflict, and if you buy both, run the current first and the light afterwards.
What each one does
Red light therapy works by photobiomodulation: light at particular wavelengths is absorbed by structures inside skin cells, which alters cell behaviour over repeated exposures. It does not heat the tissue meaningfully at consumer doses.
Microcurrent passes a small electrical current through the tissue, in the hundreds of microamps for consumer devices, which is below the level at which nerve and muscle respond and within the range studied for cellular effects.
So both are working on skin cells, by different physical routes, and both take weeks of repetition before anything durable appears.
Neither one is doing anything to the muscle underneath, and that is the most important sentence in this comparison.
What the evidence supports
Lee and colleagues ran a split-face LED study that remains one of the more useful references before buying anything light-based.
Kwak and colleagues ran a split-face design in the current world, finding that the microcurrent side improved eye-wrinkle volume and dermal density, which is the clearest single demonstration of what that band delivers.
For the muscle question, Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness across twelve weeks, using stimulation far above the microcurrent band, which is the level neither of the two technologies in this comparison reaches.
In both fields the same caution applies: most studies test a mechanism rather than a specific consumer device, so a citation supports the category rather than the product on the page.
Practical differences
Coverage. A mask treats the whole face at once while you do something else; a wand treats the area you hold it against and asks for your hands and attention.
Session length. Light masks typically run three to ten minutes depending on the device; microcurrent routines run ten minutes or longer because you are moving the probe.
Consumables. Most light devices need nothing; most microcurrent devices need a conductive layer, and around half the brands require their own at $24 to $100 a bottle.
Compliance. Hands-free wins, consistently, and the treatment you actually do beats the one you skip.
Published figures worth knowing
On the light side, HigherDOSE publishes 50 mW/cm2 on its own page and files a delivered dose of 30 J/cm2, Omnilux publishes about 30 mW/cm2, and Shark files 128 mW/cm2 with doses up to 431 J/cm2 without publishing any of it on the product page.
On the current side, published consumer figures run from about 200 microamps up to 680, with almost none stating the load the figure was measured at.
Our GLOW publishes 1.13 W/m2 and 678 J/m2 for its light layer, which converts to 0.113 mW/cm2 and 0.068 J/cm2, and is far less light than a dedicated mask delivers. We publish the conversion rather than the flattering number.
Every figure we could find across 33 devices is collected in one table.
Why neither changes contour
The layer that holds the lower face up is muscle, and muscle changes when it is asked to work, which requires current above the motor threshold.
Light cannot do that at any irradiance, because light is not current. Microcurrent cannot do it either, because it sits below the threshold by design, and its manufacturers generally say so.
So if your complaint is that the shape of your face has changed rather than its surface, neither of these two is the answer, and the jawline article sets out how to tell which complaint you have.
Owning both
They stack without conflict, and the order that makes sense is current first, then light, because you finish with circulation already brought to the area.
If you can only buy one and your concern is texture, tone or breakouts, buy light, and buy one that publishes its irradiance.
If your concern is a fresher, better-toned look at skin level and you like the ritual of working the face by hand, buy microcurrent.
If your concern is the line of your jaw, buy neither of these two categories, and read the jawline piece above first.
