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.

Feeding your skin more oxygen and nutrients is one of the most repeated claims in the facial device category, and one of the least examined.
This article covers what actually decides the answer, such as:
- Taking the claim apart
- What radiant actually describes
- The delivery mechanism that does hold up
- Where the muscle evidence sits
- How to get the most out of a session
and many more!
Here is what the claim would need to be true, why it does not survive that test, and the one delivery mechanism in the PureLift range that does have measurable physics behind it.
Key Points:
Healthy facial skin is not short of oxygen or nutrients, so there is no deficit for a device to correct.
Nobody has measured a link between a brief post-session flush and any change in collagen synthesis, barrier function or cell turnover.
Radiant describes how light behaves on a surface, which is why hydration and a smooth surface change it faster than anything electrical.
Infuse is different, electroporation is a documented physical mechanism for moving molecules across the outer skin barrier, and every PureLift model has it.
Three minutes per side is the maximum on every model, around ten minutes for a full session including Infuse.
Taking the claim apart
The argument runs in three steps, stimulation raises blood flow, blood carries oxygen and nutrients, therefore your skin gets more of both and looks better.
Each step sounds reasonable on its own, which is exactly why the chain gets repeated without anyone checking the joints between the steps.
The first joint fails because a temporary rise in surface flow is not the same as a sustained increase in delivery to the tissue, the vessels return to baseline within minutes to hours.
The second fails because skin on a healthy face is already adequately supplied, so more of something you already have enough of does not produce a proportional benefit.
The third fails hardest, because no study has followed a home facial device from a flush through to a measured change in how skin is built.
What radiant actually describes
Radiance is an optical description, it is about how evenly light reflects off the surface of the skin rather than about what is happening several layers down.
A smooth, well-hydrated surface reflects light coherently and reads as luminous, while a dry or rough surface scatters light and reads as dull, and both states can exist on the same face within a day of each other.
That explains why hydration, gentle exfoliation and simply not sleeping badly move radiance faster than any current does, and why a device that leaves a well-formulated serum sitting on well-prepared skin can honestly claim a visible difference without invoking oxygen at all.
The delivery mechanism that does hold up
Electroporation is the use of brief electrical pulses to temporarily increase the permeability of the outer skin barrier, allowing molecules to cross that would otherwise be held back.
Prausnitz and colleagues established the principle for transdermal delivery in 1993 (10.1073/pnas.90.22.10504), and it remains a documented physical mechanism rather than a marketing metaphor.
Infuse is the PureLift implementation of that mechanism, and it is on all five models, PureLift Face, Pro, Pro Edition, Pro Plus and GLOW, not reserved for the higher-priced devices.
The honest boundary is that how much of a given ingredient crosses depends on the molecule, the formulation and the settings, so Infuse improves the odds of a serum reaching past the surface, it does not make every serum work.
Where the muscle evidence sits
The strongest facial evidence in this whole category concerns muscle rather than nutrition, Kavanagh 2012 randomised 108 women over 12 weeks and reported a mean increase in zygomaticus major thickness under a defined facial NMES protocol (10.1111/jocd.12007).
That trial did not use a PureLift device and did not measure radiance, oxygen or nutrient delivery, so it supports the muscle part of the story and nothing else.
Setting expectations against that evidence rather than against the nutrition claim is the difference between being satisfied with your device and feeling misled by it.
How to get the most out of a session
Start on clean skin with a water-based conductive medium, since oil-based products block the electrical path and will make the whole session feel weaker.
Work at the lowest intensity that gives you a clear, comfortable contraction, three minutes per side maximum, then follow with Infuse and the serum you actually want delivered.
Consistency across weeks is what the trial evidence rewards, a longer session tonight is not a substitute for four short ones this week.
Your skin will look brighter afterwards, that is a real and pleasant thing, and PureLift would rather tell you exactly what caused it than sell you a story about feeding your face.
Two related questions come up often alongside this one, and we have answered both in full: the five questions to ask before buying anything, and what the twelve weeks actually look like.
