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.

A filler adds volume where volume has been lost; a stimulation device loads the muscle that supports what volume is left.
This article sets out what to check before you start, such as:
- What a filler does
- What a device does
- Telling which half you need
- Using both
- The order that usually makes sense
and many more!
Working out which half your own face needs is the useful step, and it is not hard to do in a mirror.
Key Points:
Hollow where there used to be fullness is volume, and no current creates fat.
Softened contour with the fullness still present is more likely tone and support.
Filler placement is a clinical decision and the anatomy involved is not trivial.
No research covers a device used over placed filler, so the injector sets that.
A device page claiming to be a filler alternative is describing a different mechanism.
What a filler does
It places material into tissue to restore or add volume where the face has lost it. Facial fat sits in discrete compartments rather than an even layer, and those compartments lose volume and drift downward over time.
The result is a hollow upper cheek and often a heavier lower face at the same time, since the fullness that used to sit high now rests lower.
A filler addresses that directly by replacing what left, and it is the only approach that does.
Placement, product and quantity are clinical decisions, and the anatomy in the midface is not forgiving, which is why this belongs with a qualified practitioner rather than being shopped for on price.
What a device does
It loads muscle. EMS crosses the motor threshold so the muscle contracts, and muscle responds to being loaded.
Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness over 12 weeks of motor-level facial stimulation across 108 women (10.1111/jocd.12007).
Facial muscle is part of the structure holding the midface and jawline up, so better tone means better support under whatever is above it. That is a real and limited claim.
It does not create fat, and no honest version of the argument says otherwise.
Telling which half you need
Compare a photograph from ten years ago in similar light. Hollowness where there used to be fullness points to volume; the same fullness sitting lower points to support.
Look at your face lying down. If it looks noticeably better horizontal, gravity acting on descended tissue and reduced support is a large part of it.
Press gently under the cheekbone. A cheek that feels empty is a different problem from a cheek that feels full but sits low.
Most people over forty-five have both to some degree, in different proportions, and the sensible plan addresses the dominant one first.
Using both
There is no conflict in principle, since they act on different tissues, and plenty of people reasonably do both.
The practical question is working a probe over an area where filler has been placed, and that is the injector's call rather than ours. No published research covers it, so nobody can quote you an evidence-based interval and anyone who does has invented it.
Ask before your appointment rather than after, and bring specifics: the device, the output, the areas you work and how often.
Injectors routinely give aftercare instructions about pressure and massage, and those instructions govern.
The order that usually makes sense
If volume loss is the dominant change, address that first, since no amount of muscle tone compensates for a compartment that has emptied.
If contour has softened while fullness is largely intact, the device addresses the relevant half and is the cheaper place to start.
Either way the timeline differs sharply: a filler shows immediately and lasts months to a couple of years, while a device shows at about twelve weeks and holds while you keep using it.
The claim we are not making
A device is not a filler alternative. Anybody marketing one as a way to avoid injectables is selling a different mechanism to someone with a volume problem, and they will be disappointed in three months.
If what is bothering you is hollowness, a consultation tells you more than any article, and that includes this one.
For the timing question, see facial devices and injectables, and for the layer map, the six layers of the face.
This is general information and not medical advice.
Two related questions come up often alongside this one, and we have answered both in full: what the nerve damage question actually comes down to, and the full safety picture, including who should not use one.
