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.

Puffiness and loss of firmness look similar in the mirror and are completely different problems underneath.
This article covers what actually decides the answer, such as:
- How to tell which one you are looking at
- What drives puffiness
- What drives loss of firmness
- What a device can and cannot do
- How PureLift approaches it
and many more!
Telling them apart changes what you should do about it, because the two respond to entirely different things and on entirely different timescales.
Key Points:
Puffiness comes and goes within a day, loss of firmness develops across years and does not resolve overnight.
The simplest test is time, if it is better by lunchtime it was fluid.
Firmness involves collagen, elastin, retaining ligaments, fat compartments and muscle, so no single input fixes it.
Facial EMS has randomised evidence for muscle thickness, which addresses the muscle contributor to firmness and does not address fluid at all.
Persistent, painful or one-sided swelling belongs with a clinician rather than a cosmetic device.
How to tell which one you are looking at
Puffiness is fluid, it arrives overnight or after a salty meal or a long flight, and it usually settles within a few hours of being upright and moving.
It tends to sit under the eyes and across the midface, it can look different on each side depending on how you slept, and it responds to time far more reliably than to anything you apply.
Loss of firmness is structural, it did not appear this morning and it will not be gone by this afternoon, and it shows most clearly along the jawline and in the fold running from nose to mouth.
The clearest test is simply the clock, take a photograph on waking and another at four in the afternoon under the same light, fluid will have moved and structure will not.
What drives puffiness
Lying flat for eight hours removes the gravitational drainage your face gets all day, which is why the morning face is the puffiest face most people own.
Salt, alcohol, crying, allergies, hormonal cycling, cabin pressure and skin irritation all shift fluid balance, and most of the shift reverses on its own.
Sleeping with the head slightly raised, moderating salt and alcohol in the evening and simply getting up and moving do more for morning puffiness than most products marketed for it.
Swelling that is persistent, painful, one-sided or accompanied by other symptoms is a different matter entirely and should be seen by a clinician.
What drives loss of firmness
Collagen and elastin decline steadily from the mid-twenties onward, which reduces how well skin recoils after it is stretched.
The retaining ligaments that anchor soft tissue to bone loosen, so the same volume of tissue sits lower on the same frame.
Fat compartments lose volume in the midface while descending toward the lower face, and the underlying bone remodels, widening orbital openings and altering the jaw angle.
Muscle tone changes alongside all of that, which is the one contributor a stimulation device has a documented route to.
What a device can and cannot do
Kavanagh 2012 randomised 108 women over 12 weeks and reported a mean increase in zygomaticus major thickness after facial NMES (10.1111/jocd.12007), which speaks to the muscle contributor to firmness.
No consumer facial device has been shown to clear a measured volume of fluid, so a device is not the answer to puffiness even though a session often makes a puffy face look better for a while.
That temporary improvement comes from a brief rise in surface blood flow rather than from drainage, and it is worth having on its own terms as long as you know what it is.
The practical consequence is that firmness is the goal you measure in months and puffiness is the one you manage with sleep position and salt.
How PureLift approaches it
All five PureLift models run nanocurrent at level one, microcurrent at level two, EMS from level three upward, and Infuse for electroporation-assisted serum delivery.
PDM varies frequency across 361 points between 1,370 and 1,730 Hz, changing frequency only, and every model is built in Japan to ISO 13485 with FDA 510(k) Class II clearance.
Three minutes per side is the maximum on every model, roughly ten minutes for a full session including Infuse.
Knowing which of the two you are actually looking at is the most useful thing in this article, because it decides whether you need a device, a different pillow, or simply an hour.
Two related questions come up often alongside this one, and we have answered both in full: how microcurrent compares with high frequency, and how microcurrent compares with radiofrequency.
