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 published facial stimulation trials run to about twelve weeks and then stop, so anything said about month eight is inference rather than evidence.
This article covers what actually decides the answer, such as:
- Where the evidence stops
- Months four to six, the plateau
- Months seven to twelve, maintenance
- What holding steady is worth
- What does not change over a year
and many more!
What can be offered is what muscle physiology predicts, what long-term users describe, and a clear line between the two.
Key Points:
A plateau after the first few months is what the physiology would predict; muscle does not thicken indefinitely.
Tone is maintained by use, so the sensible arrangement after month three is maintenance rather than stopping.
Two or three sessions a week is the usual maintenance pattern people settle into.
Holding steady over a year is itself a result, since skin continues changing with age regardless.
Anyone publishing a month-nine figure has invented it.
Where the evidence stops
Kavanagh and colleagues followed 108 women through 12 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 over a comparable span (10.3390/ijerph17113783), and Kwak and colleagues used a split-face design (10.52660/jksc.2023.29.6.1505).
All of them stop at a few months. Nobody has followed facial stimulation users for a year, and that study would be expensive, slow and commercially unrewarding, so it is unlikely to appear.
So the first quarter is evidence and the rest of the year is reasoning, and we would rather label it than blur it.
Months four to six, the plateau
Muscle does not thicken indefinitely. Adaptation slows as the tissue meets the demand being placed on it, which is why a training effect anywhere in the body flattens after the initial period.
The facial version has not been measured, and a plateau somewhere after the first few months is what the physiology predicts and what long-term users consistently describe.
Practically, this is when photographs stop showing month-on-month change, which is often read as the device failing rather than as the curve behaving normally.
It is also when most people reduce frequency, and reducing frequency here is reasonable rather than giving up.
Months seven to twelve, maintenance
Tone is maintained by use. Deconditioning is gradual, measured in weeks, so the working assumption is that continued use holds a change and stopping loses it slowly.
Two or three sessions a week is the pattern people settle into, and those who do generally say the change holds.
That is user experience rather than measurement, and it carries every bias user experience carries, including the fact that people still using a device after a year are not a random sample.
What holding steady is worth
Skin and facial structure continue changing with age whatever you do: collagen declines, fat compartments shift, bone remodels.
So a face that looks the same in December as it did in January has not stood still relative to the alternative, and that is a legitimate way to read a year with no dramatic photographs in it.
It is also a considerably less exciting claim than the category usually makes, which is why it is worth stating plainly.
What does not change over a year
Volume, since EMS works muscle and no current creates fat. A face that hollowed over the year hollowed for reasons a device does not address.
Dermal collagen, which responds to retinoids and to heat-based treatments rather than to current.
Anything structural, since nothing is repositioned.
If your photographs over a year show a change in those, the device was never the relevant variable.
How to track a year honestly
Monthly photographs in the same light, at the same distance, with the same expression and head position, compared against day one rather than against last month.
Expect the visible change to concentrate in months two and three and to flatten afterwards.
Keep a note of the level and the frequency alongside, since both drift over a year and both matter when you look back.
Three minutes per side is the maximum on any PureLift model throughout, and doing more in month six does not restart anything.
The line we are drawing
Twelve weeks is measured. Everything after it on this page is inference from how muscle behaves plus what users report, and we have labelled which is which.
If another brand shows you a month-nine percentage, ask which study it came from, and expect the question to end the conversation.
For the first twelve weeks, see when to expect visible results, and for the long-run evidence question, long-term use.
Two related questions come up often alongside this one, and we have answered both in full: whether microcurrent and EMS are the same thing, and how microcurrent compares with a TENS unit.
