Daniel Grinberg, MD, FACS, es un otorrinolaringólogo certificado por la junta y cirujano de cabeza y cuello en ENT and Allergy Associates en West Nyack, NY. Obtuvo su título de médico en la Facultad de Médicos y Cirujanos de la Universidad de Columbia, completó su residencia en Otorrinolaringología en el Centro Médico de la Universidad de Nueva York y es profesor clínico asistente en la Escuela de Medicina Mount Sinai. Es miembro de la American College of Surgeons y de la American Academy of Otolaryngology.
La perspectiva quirúrgica de cabeza y cuello del Dr. Grinberg ofrece a los lectores de PureLift LAB una visión clínica más amplia, conectando la práctica de EMS en casa con la anatomía médica subyacente con el mismo rigor científico que aplicamos a cada especificación del dispositivo.

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.

A pacemaker or any implanted electronic device rules microcurrent out entirely; the thyroid rule is precautionary; most metal implants and dental work are a placement question rather than a prohibition.
This article sets out what to check before you start, such as:
- why implanted electronics are an absolute exclusion
- what the thyroid guidance rests on, and how strong the evidence is
- dental implants, plates and crowns, and what people actually feel
- fillers, threads and where the timing advice comes from
- the questions worth putting to your own doctor
and many more!
Nothing here replaces your own clinician, who knows your implant and your history and we do not.
Key Points:
Pacemakers, implanted defibrillators, neurostimulators and cochlear implants are an absolute exclusion for microcurrent and EMS.
The thyroid guidance is precautionary practice rather than a documented harm, and it is still the right side to err on.
Dental implants, crowns and plates are not an exclusion, and a metallic taste near metalwork is common and harmless.
Dermal fillers are a timing question rather than a permanent bar, and your injector sets that timing.
Metal orthopaedic hardware away from the face is not relevant to a facial device.
Implanted electronic devices, the absolute no
Applied electrical current can interfere with the sensing circuitry of an implanted device, which is why every manufacturer in this category lists pacemakers as a contraindication.
That covers pacemakers, implanted cardioverter defibrillators, neurostimulators, deep brain stimulators, vagus nerve stimulators, implanted insulin pumps with electronic control, and cochlear implants.
Distance from the face does not resolve it to the point where a brand should be reassuring you, so the answer is no rather than probably.
If you have one of these and want a facial treatment, ask your cardiologist or the clinician managing your implant, and look at non-electrical options such as light therapy instead.
The thyroid rule and what it rests on
Professional training teaches avoiding the front of the neck over the thyroid, and reputable brands repeat it.
What supports that is caution about applying current over an endocrine organ lying close to the skin surface, rather than a body of evidence showing harm from facial microcurrent.
We would rather say that plainly than dress a precaution up as a finding.
In practice the rule costs you nothing, since the thyroid area is not where facial lifting work happens anyway.
If you have Hashimoto's, Graves' or a nodule under investigation, raise it with your endocrinologist before you start.
Dental work, plates and crowns
Dental implants, crowns, bridges and plates are not a contraindication for facial microcurrent, and large numbers of people use these devices with extensive dental work.
What you may notice is a metallic taste, most often near the jaw at higher levels, which is current passing close to the nerves that carry taste and is harmless.
Some people feel a slightly sharper sensation directly over metalwork, in which case lower the level across that area or work around it.
Recent oral surgery is different, and you should wait until your dentist says the area has healed.
Fillers, toxin and threads
Dermal fillers are not a permanent bar, and the question is timing rather than prohibition.
The usual practice is to wait until swelling has settled and the filler has integrated, which practitioners commonly put at two weeks or more, and your injector's instruction outranks any general advice including ours.
Botulinum toxin has its own timing, and we have written about combining the two without compromising either.
Thread lifts are the most conservative case, and you should follow your surgeon's guidance specifically.
Permanent or semi-permanent fillers deserve a conversation before you start rather than after.
Other situations people ask about
Orthopaedic metalwork in a hip, knee or shoulder is not relevant to a device used on the face.
Metal jewellery should come off the treatment area, not for safety so much as because it interrupts the conductive layer.
A history of Bell's palsy is worth raising with your doctor, since facial nerve involvement is a specific situation that general advice does not cover.
Pregnancy, epilepsy and heart conditions are covered in our general safety article.
What to ask your doctor
Name the device, the output figure and the load, since that means more to a clinician than the word microcurrent.
For PureLift that 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.
Say where on the face you intend to use it and for how long, which is ten minutes, three minutes per side.
Take the clearance number with you: K190269, K230506, K221443 or K243587 depending on the model.
A clinician given real figures can answer properly, and a clinician given marketing language cannot.
