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 is fluid sitting in the tissue rather than being carried away, and it collects overnight because you have been lying down for seven hours.
This article explains what is actually happening, such as:
- Where the fluid comes from
- Why lymph is slow to clear it
- What makes it worse
- What actually moves it
- Where a device fits
and many more!
That is why depuffing works, and also why it is temporary by nature rather than by failure.
Key Points:
Lymph has no heart; it moves through muscle contraction, breathing and external pressure.
Sleeping flat lets fluid pool in the face, which is why puffiness peaks on waking.
Salt, alcohol and poor sleep all increase fluid retention and all show up in the face first.
Light pressure moving toward the neck does more than heavy pressure, because the vessels sit just under the skin.
Depuffing lasts hours, not weeks, and that is what it is supposed to do.
Where the fluid comes from
Blood delivers fluid into tissue continuously through the capillaries, and most of it is reabsorbed on the way back. The remainder is collected by the lymphatic system, a separate network of vessels running alongside the blood supply.
When collection lags behind delivery, the surplus sits in the tissue, and in the face there is not much room for it to sit before it becomes visible, particularly under the eyes where the skin is thinnest.
Why lymph is slow to clear it
The lymphatic system has no pump. Blood has a heart; lymph has one-way valves and relies on being squeezed by the muscles around it, by the movement of breathing, and by pressure applied from outside.
Lie still for seven hours and none of those three is doing much, which is precisely why puffiness peaks on waking and settles on its own an hour or two after you get up and start moving.
The facial lymph vessels run close to the surface and drain toward nodes near the ear and down the neck, which is why direction matters more than pressure when you are trying to help.
What makes it worse
Salt holds water in tissue, so a salty dinner produces a puffy morning reliably enough to be a useful experiment on yourself.
Alcohol dehydrates and disrupts sleep, and the body responds to dehydration by holding on to fluid, which is the opposite of what people expect.
Poor sleep, crying, allergies and a cold all increase it. Sleeping face-down concentrates it on whichever side was against the pillow.
Hormonal cycles change fluid balance, and so does long-haul travel; neither is a skincare problem.
What actually moves it
Light pressure directed toward the neck. The vessels are shallow, so pressing hard compresses them shut rather than emptying them, and the common instinct to really work at a puffy face is counterproductive.
Direction matters more than force: from the centre of the face outward and then down the sides of the neck, following the drainage route rather than working against it.
Cold constricts vessels and reduces the appearance quickly, which is why a cold stone or a chilled spoon under the eyes works and why the effect fades as the tissue warms.
Simply getting up and moving does a good deal of it, since muscle contraction is one of the three things lymph relies on.
Where a device fits
Moving a probe over the face with serum is a massage stroke whether or not current is flowing, so a device session delivers the drainage benefit alongside whatever else it is doing.
Muscle contraction is the other route, and it is the one only stimulation provides; a contracting muscle squeezes the vessels around it, which is the body's own mechanism rather than an external substitute for it.
Work upward and outward and finish down the neck. Keep the skin damp with a water-based serum, since a session that drags means a dry patch. Three minutes per side is the maximum on any PureLift model.
Why it is temporary, and why that is fine
You have moved fluid that will re-accumulate tonight when you lie down again. Nothing about clearing today's fluid changes tomorrow's, and a depuffing routine is maintenance rather than progress.
That is worth being clear about, because the immediate visible improvement after a session is mostly this, and mistaking it for the cumulative work leads people to think a device has stopped working when the cumulative part is slower and quieter.
If puffiness is persistent rather than morning-only, or affects one side only, that is worth mentioning to a doctor rather than treating with a facial routine.
