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.

Yes for one specific thing, on a twelve-week clock, and no for most of what the category is sold on, which is the whole honest answer.
This article walks through the actual evidence, such as:
- What has genuinely been measured, and by whom
- The gap between category evidence and brand claims
- Which claims the research does not support at all
- Why most disappointed users were using the wrong tool
- How to judge for yourself in twelve weeks
and many more!
By the end you will know what is proven, what is plausible and what is marketing.
Key Points:
Facial muscle stimulation has been measured with ultrasound and imaging, and it increased muscle thickness over six to twelve weeks.
Every one of those studies used its own device, so the evidence is category-level and not proof about any product on a shelf.
Microcurrent has real support for skin texture and none for moving a muscle, because it is not built to.
No randomised trial has compared consumer facial devices against each other, ours included.
Most people who report no result were treating a skin concern with a muscle tool or the reverse.
We sell facial devices, so a page from us headed do they work is worth reading sceptically, which is exactly the right instinct.
What follows is the evidence as it stands, including the parts that do not flatter the category.
What has actually been measured
The strongest facial evidence concerns muscle stimulation, and it is better than most people assume.
In the largest facial trial of its kind, 108 women used daily muscle stimulation for twelve weeks and ultrasound measured an 18.6 percent increase in cheek-muscle thickness, with a clear difference from the untreated group at six weeks (Kavanagh 2012).
A double-blind, sham-controlled trial in adults over 65 found muscle thickness and bite force increased after six weeks (Chang 2020), and the sham control matters because it addresses the placebo objection directly.
CT imaging in a later study showed the muscle around the eye thickening after eight weeks (Okuda 2026).
Those are measurements of tissue rather than opinion surveys, which is what makes them worth something.
What the gentler currents support
Microcurrent, meaning current in millionths of an amp, has a different and smaller evidence base.
Pooled randomised trials in wound care covering seven studies and 337 people found that adding microcurrent to standard care helped wounds close faster (Avendano-Coy 2022), which is the strongest clinical support the low-current category has.
Facial studies are smaller and none has used a sham comparison, though they report smoother texture and softer lines with regular use (Saniee 2012).
One split-face study puts both together usefully, since the microcurrent side improved eye-wrinkle volume and dermal density while the EMS side improved lifting measures (Kwak 2023).
The gap you should know about
Every study above used its own device, its own settings and its own protocol.
That makes them category evidence, showing what facial muscle stimulation can do rather than what any product on a shelf does for the person buying it.
No randomised trial has compared PureLift against NuFACE, FOREO, FaceGym or anyone else, and no competitor has one either.
Any brand claiming a head-to-head clinical win is describing a study that does not exist, and that includes us if we ever did it.
What the research does not support
Fluid drainage or detoxification in any medical sense, since no consumer facial device has been shown to clear a measured volume of anything.
Spot fat reduction, which no device, exercise or cream achieves.
Permanent results, since muscle tone returns toward baseline if you stop training it.
Collagen remodelling claims stated as fact, which sit well beyond what a handheld device has demonstrated.
Reversing aging, which is not a thing any product does.
Why most disappointed users were disappointed
The commonest reason a device seems not to work is that it was aimed at the wrong layer.
Rough texture, dullness and fine lines sit in the skin, so a muscle device will not fix them and a microcurrent device will help.
A softening jawline sits in the muscle layer, so a microcurrent device will not fix it however high its number.
A cheek that has genuinely emptied is fat, which is filler rather than any device.
The second commonest reason is dose, since the trials ran daily for twelve weeks and most people manage a fortnight.
The third is level, because a session run below the point where the muscle contracts did no muscle work at all.
How to judge for yourself
Photograph yourself before you start, with a neutral expression, in consistent light, at a fixed distance, and include a profile shot since jaw and neck change is invisible head-on.
Run three to five sessions a week for twelve weeks, at a level where you can see the muscle answer, and note the count rather than trusting your memory of it.
Repeat the photographs monthly rather than weekly, because sleep, salt and fluid move a face around more in a week than sessions do.
Then compare week one against week twelve, and be willing to conclude it did not work for you, which is a legitimate outcome.
The honest summary
Facial muscle stimulation has measured evidence behind it for building tone in the muscle layer over six to twelve weeks.
That evidence is category-level, so it justifies taking the technology seriously rather than believing any particular brand's promises.
Everything outside the muscle layer belongs to other tools, and a device sold as an answer to all of it is being oversold.
Model notes
All five PureLift models run nanocurrent at level 1, microcurrent at level 2, EMS from level 3 to 10, and Infuse as a second pass after the muscle work.
The session is three minutes on each side of the face, about ten minutes including the Infuse pass.
Face at $499 and Pro at $699 reach up to 7 milliamps, Pro Edition at $799 reaches up to 7.7, and Pro Plus + at $899 and GLOW at $999 reach up to 9, all measured at 500 ohms and always written as up to.
GLOW alone adds light, red at 634 nm cleared for the treatment of wrinkles, blue at 465 nm cleared for mild-to-moderate inflammatory acne, and purple, which is red and blue running together.
Every model is cleared through the FDA 510(k) pathway, under records K190269 for Face, K230506 for Pro and Pro Edition, K221443 for Pro Plus + and K243587 for GLOW, and clearance is a safety review rather than a promise about results.
All five are made in Japan in an ISO 13485 facility.
Anyone with a pacemaker or another implanted electronic device, anyone pregnant, and anyone with epilepsy or a seizure disorder should not use the device at all.
For the timeline, read honest expectations, and for the layers, read facial muscle anatomy.
Model figures verified on 9 September 2026 against the PureLift LAB store and FDA records K190269, K230506, K221443 and K243587. Every model runs nanocurrent, microcurrent, EMS and Infuse; consumer copy always says up to.
