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.

Facial movement changes what the mirror shows from one moment to the next, and three very different things get called movement, voluntary expression, manual massage, and electrical muscle stimulation.
This article covers what actually decides the answer, such as:
- Three kinds of movement that keep getting confused
- Why a face looks puffy in the first place
- What the facial muscle evidence actually supports
- Where the drainage claim breaks down
- How PureLift fits the movement picture
and many more!
This article separates the three, explains what the muscle evidence actually supports, and says plainly where the popular claim about moving fluid out of the face runs past the research.
Key Points:
A smile is not a treatment dose, massage is not electrical training, and a visible contraction is not a measurement of fluid.
The strongest facial evidence is Kavanagh 2012, a randomised controlled trial of 108 women over 12 weeks that reported increased zygomaticus major thickness after repeated facial NMES.
That trial measured muscle thickness, not lymph flow, not puffiness, and not an instant contour change.
All five PureLift devices run four current types, nanocurrent for skin-level support, microcurrent, EMS at motor level, and Infuse for electroporation-assisted delivery.
A session is three minutes per side, maximum, on every model, roughly ten minutes in total when Infuse is included.
Three kinds of movement that keep getting confused
Voluntary expression starts with your own motor command, your brain fires the muscle and the face changes shape.
Manual massage works from the outside using pressure and glide, it moves skin and the tissue immediately under it without asking the muscle to do anything.
EMS delivers current that triggers a contraction once the motor threshold is crossed, which is a different event again, the muscle shortens without a command from you.
Each of the three changes how the face feels or looks during the activity, and each carries completely different evidence behind it, so treating them as interchangeable is where most of the confusion in this category starts.
Why a face looks puffy in the first place
Puffy-looking describes visible fullness, defined describes clearer contours, and both words describe appearance rather than a measured quantity of anything.
Sleep position, salt, alcohol, travel, crying, allergies, skin irritation and simply the hour of the day all change how full a face looks, and most of that variation resolves on its own within hours.
Photographs exaggerate the swing, a morning shot taken close to a wide-angle phone lens and an evening shot taken from two metres away will show two apparently different jawlines on the same unchanged face.
A comparison worth trusting matches camera, distance, lighting, expression, time of day and skincare, and even then it records appearance and nothing more.
Swelling that is persistent, painful, one-sided or accompanied by other symptoms belongs with a clinician rather than with a cosmetic device.
What the facial muscle evidence actually supports
Kavanagh and colleagues ran a randomised controlled trial of facial neuromuscular electrical stimulation in 108 women over 12 weeks, and under that defined protocol reported a mean increase in zygomaticus major muscle thickness (10.1111/jocd.12007).
That is category-level evidence that facial muscle responds to repeated electrical stimulation, which is the part of the movement story with the firmest ground under it.
The trial did not use a PureLift device, did not test PDM, and did not measure facial fluid, lymph transport or an immediate change in contour.
A thickness figure cannot be converted into a promised jawline, because what a slightly thicker muscle does to the visible surface depends on bone, fat, skin quality and every other layer sitting above it.
Where the drainage claim breaks down
Contracting muscle does compress the vessels running through and around it, which is real physiology and is part of how the body moves fluid during ordinary activity.
The leap that does not follow is from that mechanism to a claim that a ten-minute facial routine has cleared a measured volume of fluid out of the face.
No consumer facial device has been shown to clear a measured volume of anything, and lymphatic drainage in the medical sense is a clinical treatment for diagnosed conditions delivered by trained therapists.
Using that phrase for a home routine borrows the authority of the clinical treatment without having earned it, which is why PureLift describes appearance rather than promising drainage.
How PureLift fits the movement picture
All five PureLift devices run four current types from the same probe, nanocurrent at level one for skin-level support, microcurrent at level two, EMS from level three upward where motor-level contraction begins, and Infuse for electroporation-assisted serum delivery.
Level matters to the mechanism, a nanocurrent setting is not quietly doing muscle work and a strong contraction is not quietly moving fluid, each level does what its physics allows and nothing extra.
The waveform architecture, PDM, varies frequency continuously across 361 points between 1,370 and 1,730 Hz, which changes frequency only, not amplitude and not pulse duration.
Varying frequency is supported in the general literature as a way to delay the onset of fatigue during stimulation, so the honest framing is that PDM is an engineering choice about how the signal is delivered, not a second mechanism layered on top.
Every device is built in Japan in facilities operating to ISO 13485, and every model carries FDA 510(k) Class II clearance.
What a sensible routine looks like
Three minutes per side is the maximum, on every model, and the figure is a ceiling rather than a target you should work up to for its own sake.
Adding Infuse brings a full session to roughly ten minutes, which is still short enough to fit either end of the day without rearranging anything.
Longer is not better and twice daily is not better, muscle responds to consistent stimulation across weeks rather than to a heavy single session, and the trial evidence that exists ran on modest protocols repeated over twelve weeks.
Intensity should sit at the lowest level that produces a clear, comfortable contraction, because pushing toward the top of the range buys discomfort rather than a faster result.
The honest summary
Facial movement is real, facial EMS has genuine randomised evidence behind the muscle part of the story, and both of those statements can be true while the drainage claim remains unsupported.
A face that looks less puffy after a session has changed in appearance, which is worth having, and describing it accurately costs the result nothing.
If you want the mechanism explained in more depth, the companion article on how facial muscles move fluid sets out where the physiology ends and the marketing begins.
Two related questions come up often alongside this one, and we have answered both in full: what the depuffing effect really is, and why a twelve pound stone does much of the same job.
