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.

Ten programs on a facial device sounds like ten times the capability, and it is usually one capability presented ten ways.
This article covers what actually decides the answer, such as:
- What a program actually is
- Why the named programs are usually theatre
- The three specifications that do matter
- How PureLift is arranged
- What to do with a device you already own
and many more!
This article explains what a program actually is on a device like this, why the count tells you almost nothing, and the three specifications that do matter.
Key Points:
A program is usually a stored set of numbers, not a separate technology.
A device can list ten programs and never cross the motor threshold in any of them.
Named programs for eyes, jaw and neck are often the same output relabelled.
What to check instead is maximum output, whether contraction occurs, and how the waveform is delivered.
PureLift runs levels rather than named programs, with the motor threshold crossed at level three.
What a program actually is
Inside almost any stimulation device, a program is a stored combination of frequency, pulse duration, intensity ceiling and timing.
Adding another program means storing another combination in firmware, which costs the manufacturer nothing and adds a number to the box.
Nothing about a longer list tells you whether any entry on it produces a contraction, and that is the only question that separates a muscle device from a surface device.
A device with one setting that crosses the motor threshold is doing more muscle work than a device with ten that never do.
Why the named programs are usually theatre
A program called Eye Lift and one called Jawline Sculpt sound like different treatments, and are frequently the same output with a different label and a different timer.
The device has no way of knowing where on your face it is, so any area-specific behaviour has to come from you moving the probe rather than from the program selection.
If a manufacturer claims a program is genuinely tuned to a region, the reasonable thing to ask is what changes numerically between the two, and most cannot answer.
A longer menu also makes a device harder to use, since more choices without a stated difference produce hesitation rather than better sessions.
The three specifications that do matter
Maximum output comes first, published as a real figure in milliamps or microamps rather than as a word like powerful, and a brand that will not publish a number has told you something by declining.
Whether the device crosses the motor threshold comes second, because a visible, palpable contraction is a different physical event from a tingle, and most devices marketed as microcurrent never produce one.
How the waveform is delivered comes third, since varying frequency during a session is supported in the general literature as a way to delay the onset of fatigue.
Those three are checkable before you buy, and a program count is not.
How PureLift is arranged
PureLift uses levels rather than named programs, which is a deliberately plainer arrangement, level one is nanocurrent, level two is microcurrent, and level three upward is EMS.
Level three is where the motor threshold is crossed on every model in the range, so the point at which muscle work begins is stated rather than hidden inside a menu.
Infuse is separate and is on all five models, using brief electrical pulses to temporarily raise the permeability of the outer skin barrier (10.1073/pnas.90.22.10504).
PDM sits underneath all of it, varying frequency across 361 points between 1,370 and 1,730 Hz and varying nothing else, which is a description rather than a claim of superiority since no head-to-head facial trial exists.
What to do with a device you already own
Find the lowest setting that produces a clear, comfortable contraction and use that, rather than cycling through programs looking for one that feels different.
Three minutes per side is the maximum on any PureLift model, around ten minutes for a full session including Infuse.
Kavanagh 2012 got its measured increase in zygomaticus major thickness from 12 weeks of repeated sessions under one protocol (10.1111/jocd.12007), which is a useful reminder that repetition did the work rather than variety.
