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.

Five beliefs about facial EMS that are repeated constantly and are either wrong or badly overstated.
This article covers what actually decides the answer, such as:
- One, stronger is not faster
- Two, longer is not better
- Three, it does not drain your face
- Four, what you see afterwards is not the result
- Five, microcurrent and EMS are not the same
and many more!
Getting these right will change how you use the device you already own.
Key Points:
The right intensity is the lowest one that produces a clear, comfortable contraction.
Three minutes per side is a ceiling on every PureLift model, not a target to exceed.
No consumer facial device has been shown to clear a measured volume of fluid.
The post-session look fades within hours; the change worth measuring takes weeks.
Microcurrent sits below the motor threshold and EMS crosses it, which is a real physical difference.
One, stronger is not faster
Once the motor threshold is crossed, the muscle is contracting, and pushing the dial higher makes the contraction more forceful and more uncomfortable without making it more productive.
Higher intensity also brings fatigue on sooner, so the last minutes of a session at a punishing level are doing less than the first minutes did.
The trial evidence that exists came from modest protocols repeated consistently, not from anyone maximising the dial, so the sensible setting is the lowest that gives a clear, comfortable contraction.
This is also why the 9 mA models are headroom rather than capability, since most people never approach their device's ceiling.
Two, longer is not better
Three minutes per side is the maximum on every PureLift model, and it is a ceiling rather than a figure to build up from.
Muscle fatigues under electrical stimulation faster than under voluntary effort, so extra minutes past the point of fatigue add irritation rather than stimulus.
A short session done four times this week beats a long one done once, and the long one is also the version people quietly stop doing.
Three, it does not drain your face
Contracting muscle does compress the vessels running through and around it, which is genuine physiology, and it is not the same as a measured volume of fluid leaving your 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.
A face that reads as less puffy after a session has usually changed in tone and surface colour, which is worth having and is a different statement.
Four, what you see afterwards is not the result
The immediate tighter, brighter look comes from a brief rise in surface blood flow and from freshly worked muscle, and it fades within hours as the vessels return to baseline.
Treating that as the outcome leads people to conclude the device stopped working by Thursday, when nothing has gone wrong at all.
The change worth measuring is muscle, and Kavanagh 2012 randomised 108 women over 12 weeks to report a mean increase in zygomaticus major thickness after facial NMES (10.1111/jocd.12007).
Twelve weeks is the clock, so judge the device in photographs taken three months apart under matched light, camera and expression.
Five, microcurrent and EMS are not the same
Microcurrent operates below the motor threshold, so the muscle never contracts, and most devices sold as microcurrent stay below that line across their entire range.
EMS crosses the threshold and produces a contraction you can see and feel, which is a genuinely different physical event rather than a stronger version of the same one.
On PureLift the two are settings on one device, level two is microcurrent and level three upward is EMS, with nanocurrent below both at level one and Infuse for serum delivery (10.1073/pnas.90.22.10504).
All four run on all five models, from Face at $499 upward, so the distinction is one you can explore on any of them.
What to change tonight
Turn the intensity down to the lowest clear contraction, keep to three minutes per side, and use a water-based conductive medium generously.
Take a photograph today under decent light and put a reminder in your calendar for twelve weeks from now, then stop checking the mirror in between.
Every PureLift model is built in Japan to ISO 13485 with its own FDA 510(k) Class II clearance, and none of that matters if the device sits in a drawer.
