Dr. Andrew Conrad Barile is a Doctor of Physical Therapy and the CEO and Founder of Xtreem Pulse LLC, the engineering company behind PureLift. He earned his Doctorate in Physical Therapy from Daemen College and is a licensed physical therapist.
He brings over two decades of clinical and entrepreneurial experience across physical therapy, craniosacral therapy and medical device innovation, built on a working knowledge of human anatomy and muscle physiology.
For PureLift LAB he reviews how current is delivered across all ten levels, from sub-sensory nanocurrent and skin-level microcurrent to motor-level EMS, and how the Infuse pass fits into the same ten-minute routine.

Daniel Grinberg, MD, FACS is a board-certified otolaryngologist and head and neck surgeon at ENT and Allergy Associates in West Nyack, New York. He earned his medical degree from Columbia University College of Physicians and Surgeons.
He completed his otolaryngology residency at New York University Medical Center, serves as Assistant Clinical Professor at Mount Sinai School of Medicine, and is a Fellow of both the American College of Surgeons and the American Academy of Otolaryngology.
For PureLift LAB he brings a wider clinical lens, connecting at-home facial stimulation from microcurrent to EMS to the anatomy underneath, with the same rigour we apply to every device specification.

A TENS unit is designed to interrupt pain signals in the body at currents far above facial levels, with electrodes sized for the back rather than the face, and it is not a substitute for a facial device.
This article sets out what to check before you start, such as:
- what a TENS unit is built to do
- the current and electrode differences that matter
- the odd regulatory overlap between the two categories
- why people try it anyway, and what goes wrong
- what to use instead if budget is the issue
and many more!
Please do not improvise with a pain device on your face, whatever a forum post says.
Key Points:
TENS stands for transcutaneous electrical nerve stimulation, designed for pain relief, typically operating in the tens of milliamps.
TENS pads are large, adhesive and shaped for the back, shoulder or knee, not for the contours of a face.
Facial aesthetic devices are, oddly, cleared under the same FDA regulation as TENS devices, which is a regulatory artefact rather than a statement of equivalence.
A TENS unit has no facial protocol, no facial clearance, and no manufacturer support for facial use.
Cheaper facial options exist, from about $120, which is a better answer than improvising.
What a TENS unit is for
TENS stands for transcutaneous electrical nerve stimulation, and the purpose is pain management. The current stimulates sensory nerves to interfere with pain signalling, and at higher settings it can produce muscle twitching as a side effect rather than as the goal.
Typical operating currents run in the tens of milliamps, which is an order of magnitude or more above what facial devices use.
The pads are large and adhesive, designed to sit on a back, a shoulder or a knee and stay there while you go about your day.
None of that design brief has anything to do with a face.
The differences that matter
Current. A facial microcurrent device runs in the hundreds of microamps and a facial EMS device in single-figure milliamps at a stated load. A TENS unit can run far above both.
Electrode size and placement. Current density is current divided by contact area, so the same current through a small facial probe behaves very differently from the same current through a large adhesive pad. Improvising with pads on a face changes the density in ways nobody has characterised.
Protocol. Facial devices come with placement guidance built around facial anatomy. A TENS unit comes with guidance for lower back pain.
Ward and colleagues described the thresholds separating sub-sensory, sensory and motor stimulation, and a device designed to sit comfortably above the sensory threshold on a back is not calibrated for the tissue over your jaw.
The regulatory overlap, explained
Here is a genuine curiosity that causes confusion: most facial aesthetic stimulators are cleared under 21 CFR 882.5890, the regulation covering transcutaneous electrical nerve stimulators for pain relief.
NuFACE, ZIIP, Ya-Man, 7E and our own devices all sit under that regulation or its aesthetic product code.
That is a regulatory filing artefact, reflecting how the FDA categorises electrical stimulators, rather than a statement that the two device types are interchangeable.
The indications for use on a facial device say cosmetic facial stimulation, and the indications on a TENS device say pain relief. Those sentences are what each device was actually cleared for.
Why people try it anyway
Cost, mostly. A TENS unit can be bought for very little, and the reasoning that electricity is electricity is superficially appealing.
Some people also come from physiotherapy, where TENS and NMES are familiar, and reason from body experience to facial use.
What goes wrong is uncomfortable sessions, uneven current from pads that do not fit facial contours, and no way to know what is arriving where.
The face also has structures worth respecting, including the facial nerve and the eye, which a back-oriented device gives you no guidance about.
If budget is the real question
Skin Gym's wand is $120, NuFACE MINI+ lists at $250 with frequent $175 pricing, and Solawave is $169. Those are real devices with facial clearances and facial protocols.
Any of them is a better answer than improvising with a pain device, and all three are cheaper than an emergency appointment if something goes wrong.
If none of that is affordable right now, the honest advice is to wait rather than improvise, and to spend the interim on sun protection and sleep, which cost nothing and do more than most devices.
The safety line
Do not use any electrical stimulation device, TENS or facial, if you have a pacemaker or another implanted electronic device.
Do not use a TENS unit across the head, neck or face, which is outside its instructions on essentially every unit sold.
Ask a doctor first if you are pregnant, epileptic or have a heart condition, which we set out fully in the safety article.
And read the actual indications on whatever you own, which takes a minute and settles most of these questions.
