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.

Glow is a word about light, not about physiology, and treating it as a physiological outcome is how the circulation claim took over this category.
This article covers what actually decides the answer, such as:
- Two things combine to make a glow
- How long the device version lasts
- Why the improved circulation phrasing overreaches
- What moves glow more reliably
- Where PureLift fits
and many more!
Here is what actually produces a glow, how long a device-induced version lasts, and what changes it more reliably than any handheld.
Key Points:
Glow is how evenly light reflects off the surface of your skin, plus how much colour sits in the vessels beneath it.
A device session raises surface blood flow briefly, which produces a real glow lasting minutes to hours.
No home facial device has been shown to produce a lasting change in facial circulation.
Surface smoothness and hydration move glow faster than anything electrical does.
Three minutes per side is the maximum on all five PureLift models, roughly ten minutes with Infuse.
Two things combine to make a glow
The first is the surface, a smooth, well-hydrated outer layer reflects light in a consistent direction and reads as luminous, while a rough or dehydrated surface scatters light in every direction and reads as dull.
The second is colour from beneath, since the small vessels close to the surface contribute warmth, and how full those vessels are changes minute to minute.
A facial device can move the second one temporarily, and skincare and hydration move the first one, which is why the two approaches feel different and why both have a place.
How long the device version lasts
Stimulation, warmth and friction all raise surface flow briefly, which is why a hot shower, a brisk walk and a facial session all leave you looking similar afterwards.
The vessels return to their baseline within minutes to hours, and the glow leaves with them, which is not a fault of the device but a description of what a flush is.
Timing a session an hour before you want to look your best is therefore a perfectly sensible thing to do, and expecting the effect to still be there on Thursday is not.
Why the improved circulation phrasing overreaches
A temporary rise in surface blood flow and an improvement in circulation are different claims, and the second implies a durable change to the vascular network.
Demonstrating that would require baseline measurement, a controlled protocol and follow-up months later, and nobody has done it for a home facial device.
The study most often cited here tested a device combining NMES, iontophoresis, LED and cooling, and measured blood flow at week eight rather than during a session, so it cannot support either claim about a single technology.
A 2026 correction to that paper disclosed manufacturer employment among the authors and manufacturer supply of the devices, stating the results were unchanged.
What moves glow more reliably
A humectant-rich moisturiser applied to slightly damp skin smooths the surface within minutes, which changes reflection more than a flush changes colour.
Gentle, infrequent exfoliation removes the rough surface layer that scatters light, and overdoing it produces the opposite of what you wanted.
Sleep and daily sun protection are the two habits that decide what your baseline looks like, and no device improves on either.
Where PureLift fits
All five PureLift models run nanocurrent at level one, microcurrent at level two, EMS from level three upward, and Infuse for electroporation-assisted serum delivery, so the glow effect is available on every model rather than being a premium feature.
Infuse is the part of the routine that actually serves glow, since it uses brief pulses to temporarily raise the permeability of the outer barrier, a mechanism established for transdermal delivery by Prausnitz and colleagues in 1993 (10.1073/pnas.90.22.10504).
PureLift GLOW additionally carries LED at 634 nm red and 465 nm blue, usable separately or together, which is the only model with light built in.
Every model is built in Japan to ISO 13485 and carries FDA 510(k) Class II clearance, and three minutes per side is the maximum on all of them.
You will glow after a session, that is real and pleasant, and it is worth more coming from a brand willing to tell you how long it lasts.
