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.

The longest published trials of facial electrical stimulation run about twelve weeks, so there is no study covering what happens in year two or year five.
This article covers what actually decides the answer, such as:
- What the twelve weeks show
- What muscle physiology reasonably implies
- What stopping appears to do
- Safety over the long run
- What long-term users describe
and many more!
What can be said is what the twelve-week evidence shows, what the muscle physiology implies, and what stopping does.
Key Points:
Kavanagh's trial ran 12 weeks with 108 women and measured an 18.6 percent increase in cheek muscle thickness.
No published trial follows facial stimulation users beyond a few months.
Muscle tone is maintained by use, so the reasonable expectation is that stopping reverses gains gradually.
There is no evidence of accumulated harm from long-term use within the instructions, and no evidence of unlimited gains either.
Three minutes per side is the maximum on any PureLift model, and more is not better.
What the twelve weeks show
Kavanagh and colleagues followed 108 women through twelve weeks of motor-level facial stimulation and measured an 18.6 percent increase in cheek muscle thickness (10.1111/jocd.12007). Chang and colleagues ran a double-blind sham-controlled trial on facial stimulation (10.3390/ijerph17113783), and Kwak and colleagues ran a split-face design (10.52660/jksc.2023.29.6.1505).
Those are category studies, not trials of any consumer device, and the measurement windows are all short. What they establish is that motor-level stimulation changes facial muscle over a season, under a protocol.
What they cannot establish is the shape of the curve after that season, because nobody has measured it.
What muscle physiology reasonably implies
Facial muscles behave like other skeletal muscle in the respects that matter here: they respond to load, and the response is maintained by continuing to load them. That is why the gym analogy keeps coming up, and it is a reasonable analogy for the direction of travel even though nobody has run the facial version of the study.
The honest phrasing is that continued use is more likely to hold a change than stopping is, and that is inference from how muscle works rather than a finding from a trial.
It also implies a ceiling. Muscle does not thicken indefinitely, and a plateau after the first few months is what the physiology would predict, which matches what long-term users tend to describe.
What stopping appears to do
Deconditioning in skeletal muscle is gradual rather than sudden, measured in weeks rather than days. Applied to the face, the reasonable expectation is that a break of a fortnight costs little and a break of six months costs most of what was gained.
No study measures this for facial muscle, so treat it as the sensible working assumption rather than a documented fact.
The practical consequence is that a schedule you can sustain at a lower frequency beats an intense one you abandon in March.
Safety over the long run
PureLift devices are cleared 510(k) Class II: Face under K190269, Pro and Pro Edition under K230506, Pro Plus under K221443, and GLOW under K243587. Clearance covers the stated intended use and is not a statement about decade-long use, because that is not what clearance examines.
There is no published signal of accumulated harm from using facial stimulation within its instructions, and there is also no long-horizon study that would be capable of finding one. Both halves of that sentence are true and should be read together.
The instructions matter more than the duration. Three minutes per side is the maximum on any PureLift model, and the ten minute session ends on its own; running longer or higher does not accelerate anything and is outside what the device was cleared for.
What long-term users describe
The common pattern reported is a change over the first two to three months, then a plateau, then maintenance at a lower frequency. People who drop to a couple of sessions a week after the initial period generally say the change holds.
That is user experience rather than measurement, and it is subject to every bias that user experience carries, including the fact that people who kept using a device for three years are not a random sample.
Worth noting alongside it: skin quality changes with age regardless of what you do, so holding steady over several years is itself a result rather than a null one.
How to judge your own long run
Photograph monthly rather than daily, in the same light, at the same distance, with the same expression. Fold depth and contour change far too slowly to read day to day, and the daily check mostly measures sleep and salt.
Keep a note of the level you are using. Drifting upward over time is common and is usually accommodation rather than need; PDM cycles through 361 frequency points between 1,370 and 1,730 Hz specifically to delay that drift.
If a level that used to feel like work now feels like nothing, that is worth reading as adaptation rather than as a reason to climb the dial.
