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.

Facial puffiness genuinely responds to a session, and no published study has measured lymph flow during facial microcurrent, so the movement and pressure are the better-supported explanation.
This article sets out what to check before you start, such as:
- what the facial lymphatic system actually does
- why the same-day depuffing effect is real
- what has and has not been measured
- how direction and pressure matter more than the setting
- when puffiness is a medical question
and many more!
This is the one area where we will tell you a twelve pound tool gives you most of the same result.
Key Points:
The facial lymphatic system drains fluid toward nodes in front of and behind the ear and down the neck, and it has no pump of its own, relying on movement and surrounding muscle.
Muscle contraction does assist lymphatic return elsewhere in the body, which makes the mechanism plausible for facial stimulation rather than proven.
No published trial has measured facial lymph flow before and after a microcurrent session, so nobody can quantify the contribution of the current.
Direction and pressure are what move fluid, which means technique matters far more than the level you choose.
Persistent one-sided swelling, swelling with pain or redness, or swelling that does not settle through the day warrants a doctor rather than a device.
What the facial lymphatic system does
Lymph is the fluid that leaves the small blood vessels and bathes the tissues, and it returns through a network of thin vessels rather than through the veins.
On the face, that network drains toward nodes sitting in front of the ear, behind the ear and along the neck, which is why every drainage technique ends by moving fluid downward toward the neck.
Unlike blood, lymph has no central pump, and it moves because vessel walls contract weakly and because surrounding muscle and external pressure squeeze it along.
Overnight, lying flat, fluid accumulates in the face, which is why morning puffiness is normal and why it settles through the day on its own.
Why the effect you see is real
A morning session that leaves your face looking less swollen is not imagined; fluid has moved.
What moved it is the combination of external pressure from the probe, the direction you travelled, and, in an EMS device, the muscle contraction underneath.
Muscle contraction assisting lymphatic and venous return is well established in the limbs, which is the basis for compression and movement advice after surgery.
Extending that to facial muscles is a reasonable inference. It is not the same as a measurement, and we are not going to present it as one.
What has not been measured
We can find no study that imaged or quantified facial lymph flow before and after a microcurrent or facial EMS session.
That means the share of the depuffing attributable to the current, as against the pressure and the direction of travel, is unknown.
It also means a brand attributing depuffing specifically to its waveform or its frequency is describing marketing rather than findings.
The measurement would not be difficult to do, and its absence across a category this large is telling.
Technique is what matters here
Work from the centre of the face outward and then down the neck, finishing each pass toward the collarbone, because that is where the fluid is going.
Use light pressure. Lymphatic vessels sit just under the skin and heavy pressure works against the goal rather than for it.
Do the neck first so the route is clear before you push fluid toward it, which is the one instruction most people skip.
Morning is the sensible time, because that is when the accumulation is greatest, and our sessions run ten minutes with three minutes per side at most.
What else does the same job
A gua sha stone or a simple roller produces much of the same same-day depuffing, because the pressure and direction are doing the work. We have said this before in our comparison and we will keep saying it.
Sleeping with your head slightly raised, reducing salt the night before, and cold on the face all address the same fluid.
If depuffing is the only thing you want, buy the stone and keep the difference.
The case for a device rests on the cumulative muscle and skin outcomes across weeks, not on the morning depuff, and anyone selling you the device for the depuff alone is overcharging you.
When puffiness is a medical question
Swelling on one side only, swelling with pain, heat or redness, or swelling around the eyes that persists through the day are not cosmetic problems.
Facial swelling with difficulty breathing or swallowing is an emergency.
Persistent puffiness can also reflect thyroid, kidney or cardiac issues, and a facial device is the wrong response to any of them.
See a doctor first, and come back to the cosmetic question afterwards.
