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.

Microcurrent works on your skin and EMS contracts your muscle, and one line separates them, the motor threshold.
This article covers what each one is for, such as:
- What microcurrent actually does at skin level
- What changes the moment a muscle contracts
- The split-face study that ran both on one person
- Why owning both on one dial is more useful than choosing
and many more!
Neither is better than the other, they do different jobs on different layers.
Key Points:
Microcurrent stays below the motor threshold, so the muscle never contracts.
EMS crosses it, and you can see the cheek or jaw answer in the mirror.
Kwak 2023 ran both on one face and found microcurrent improved eye wrinkles and dermal density while EMS improved lift.
Most devices sold as microcurrent stay below the threshold across their entire dial.
On a PureLift, microcurrent is level 2 and EMS begins at level 3, so both sit on one dial.
What microcurrent does
Microcurrent delivers current measured in millionths of an amp, which is enough to reach skin cells and not enough to reach the nerve that drives a muscle.
Laboratory work shows defined small currents change how skin cells behave, affecting fibroblast migration, cellular energy production and collagen-related signalling, and small facial studies report smoother texture and softer lines with regular use (Saniee 2012).
What you feel is a mild tingle or, at the lower end, nothing at all, which is the design rather than a fault.
That is genuinely useful work on the outermost layer, and it is not muscle work, so a brand promising a lifted jawline from microcurrent alone is describing an outcome its own physics does not reach.
What EMS does
EMS delivers enough current to fire the motor nerve, so the muscle contracts without any instruction from you.
A review of kilohertz-frequency stimulation describes three thresholds in everyone, the point you feel the current, the point the muscle moves and the point it hurts (Ward 2009), and EMS lives at the second one.
This is where the strongest facial evidence sits. Kavanagh 2012 followed 108 women using daily facial muscle stimulation for twelve weeks and ultrasound measured an 18.6 percent increase in cheek-muscle thickness, with a clear difference from the untreated group at six weeks (Kavanagh 2012).
Chang 2020 tested the same idea against an identical-looking dummy device over six weeks and found muscle thickness and bite force increased (Chang 2020), which is the strictest design this field has.
The study that ran both on one face
A split-face study settles the argument better than any comparison table, because it applied microcurrent to one side of a face and EMS to the other.
The microcurrent side improved eye-wrinkle volume and dermal density, and the EMS side improved lifting measures (Kwak 2023).
Two currents, two different results, on one person under the same conditions, which is as clean a demonstration as this category offers that they are not competing versions of the same thing.
Why most devices only offer one
Published output tells you which side of the line a device sits on. FOREO BEAR 2 reaches 680 microamps, Therabody TheraFace PRO 500, ZIIP Halo 309, and NuFACE Trinity+ between 170 and 200.
All of those are below the motor threshold across their entire range, which is why they produce a tingle and never a visible twitch.
Worth noting that NuFACE, ZIIP and Therabody do not print an output figure on their own product pages, so those numbers come from their FDA clearance documents.
Having both on one dial
Every PureLift model runs nanocurrent at level 1, microcurrent at level 2 and EMS from level 3 to 10, so the choice is a setting rather than a purchase.
That matters most on the days muscle work is the wrong idea, after a late night, on reactive skin, in the week following a treatment, when you turn the dial down instead of skipping the session.
A skipped session is the real enemy here, because every measured result in this category came from repeated use across weeks rather than from any single strong session.
There is also the Infuse pass, which runs two delivery technologies on the serum already on your skin, Infusion built on electroporation (Prausnitz 1993) and iontophoresis moving charged ingredients inward through those routes.
Building the routine
Start on clean skin with a water-based conductive serum, since oil-based products do not conduct and will weaken any device of this kind.
Work at the lowest level that produces a clear, comfortable contraction, three minutes on each side at most, then run Infuse with the serum you want delivered.
The whole session is about ten minutes and switches itself off, and four sessions a week for twelve weeks is the pattern that matches the research.
If texture and radiance are what bother you, level 2 is your setting; if the softening along the jaw is the problem, that lives in the muscle layer and needs level 3 and above.
