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.

Jowls form from a combination of descending fat, loosening retaining ligaments and thinning skin, and a current-based device reaches the muscle contribution only.
This article covers what actually decides the answer, such as:
- what a jowl is actually made of
- which part of it responds to stimulation and which does not
- why early jowls respond better than established ones
- what twelve weeks of honest work can and cannot deliver
- the point at which a surgeon is the right answer
and many more!
This is the article in the set where we have the least to promise, and it is written that way.
Key Points:
A jowl is mostly descended fat and lax retaining ligaments, with muscle tone and skin quality contributing.
Electrical stimulation reaches the muscle contribution and nothing else, which is a minority of what you are looking at.
Early softening along the jaw responds considerably better than an established jowl.
Nothing at home lifts a fat pad back up the face, and any brand suggesting otherwise is overselling.
A well-formed jowl is a surgical or procedural question, and we would rather say so than take the sale.
What you are actually looking at
The jowl is the pad of soft tissue that hangs just forward of the jaw angle, and it forms as facial fat compartments lose volume high in the cheek and descend, meeting the restriction of the retaining ligaments along the jaw.
Three separate things contribute. Fat that used to sit high has moved downward. The ligaments that tether soft tissue to bone have loosened. And the skin has lost some of the recoil that used to hold everything against the frame.
Muscle tone contributes too, particularly through the platysma and the depressor muscles at the corner of the mouth, and it is the smallest of the four contributions in most faces.
That proportion is the whole problem, because muscle is the only one of the four that electrical stimulation touches.
What stimulation actually reaches
Ward and colleagues described the thresholds separating sub-sensory, sensory and motor current, and above the motor threshold a muscle shortens and, with repetition, adapts.
Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness in 108 women over twelve weeks at that level, and the measurement was taken at the cheek rather than along the jaw.
A better-conditioned platysma and a better-conditioned mid-face can improve how the jaw reads, because more supported tissue above the jawline means less spilling over it.
What stimulation cannot do is move a fat pad back up the face or retighten a ligament. No current at any amperage does either, ours included.
Why early jowls respond better
Softening along the jaw that comes and goes with sleep and fluid is largely positional, and that responds quickly to almost anything that moves fluid, including a single session.
Early jowling, where the line is still mostly intact and the shadow appears only in certain light, has a meaningful muscle contribution and often improves noticeably over twelve weeks.
An established jowl, visible from straight on in any light and unchanged when you lie down, is dominated by fat and ligament, and twelve weeks of work will change it very little.
The lying-down test is the most useful thing in this article. If the jaw looks substantially better flat on your back, the soft tissue is still mobile. If it looks much the same, gravity is not the main factor.
What twelve weeks honestly delivers
On an early jowl, a cleaner line from the chin to the jaw angle, a shadow that appears in fewer lighting conditions, and a face that photographs better from three-quarter angles.
On an established jowl, some improvement in the tissue above it and very little in the jowl itself.
In both cases, a same-day fluid effect after each session that flatters the area temporarily and should not be mistaken for the durable change.
If you want to judge it properly, photograph from slightly below the chin at week zero and week twelve under identical light, which is the least flattering angle and therefore the only honest one.
Working the area properly
Run the pass under the jawbone from near the chin outward to the angle below the ear, following the platysma rather than sweeping across it.
Spend more of your three minutes here than anywhere else, because this is where your complaint is.
Work the mid-face as well, even though the jowl is lower, since supporting the tissue above the jaw does more for the line than working the jowl itself.
Our diagram article sets out the directions, and the muscle chart explains which muscle each pass follows.
When to stop reading device articles
If the jowl is well established, if it is visible from straight on in flat light, and if lying down does not change it, the honest options are surgical or procedural rather than electrical.
A deep plane facelift addresses ligaments and fat position, which is precisely what a device cannot. Radiofrequency and ultrasound-based treatments address skin quality and some laxity.
Injectable and thread options exist with their own trade-offs, and a consultation with someone who does not sell devices is worth more than any article, including this one.
We publish this because a brand that tells everyone its device is the answer is easy to catch out, and because the person with an established jowl who buys a device on that promise is the customer we most deserve to lose.
This article sits inside our full map of the category, where we set out all 33 devices we track, what each one carries and what each brand publishes: Nine Technologies on One Dial, What the Rest of the Market Actually Carries.
