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.

Ten checks will tell you more about a facial device than any review, and you can run all of them before you spend anything.
This is the checklist itself, such as:
- The question to answer before you look at any product
- How to read an output figure and its unit
- How to verify a regulatory claim yourself
- The recurring cost hidden in the box
- What to ignore completely
and many more!
By the end you will have a checklist you can apply to any brand, including ours.
Key Points:
Settle which layer your concern sits in first, because skin, muscle, fat and ligaments each need a different tool.
Check the unit on any output figure, since microamps and milliamps look similar and sit about a thousand apart.
A 510(k) clearance number beginning with K can be looked up in about two minutes, and FDA cleared is not FDA approved.
A required proprietary gel is a subscription attached to a one-off purchase, so price a year of it in.
Ignore mode counts, before and after photographs, and how strong a device feels in a demonstration.
Most buying advice in this category is a list of products, which goes out of date and tells you nothing transferable.
A checklist lasts, and it works on devices that have not launched yet.
1. Which layer is your concern in
Rough texture, dullness and fine lines sit in the skin, which is microcurrent and skincare territory.
A softening jawline, a cheek losing shape and a slackening neck sit in the muscle layer, which is EMS territory.
A cheek that has genuinely emptied is fat, which is filler.
Folds that stay when you press the skin flat involve ligaments, which is surgical.
Answer this before you look at a single product, because everything below depends on it.
2. The output figure, and its unit
A milliamp is a thousandth of an amp and a microamp is a millionth, so 680 microamps and 7 milliamps sit about ten times apart despite looking almost identical in small type.
A figure quoted in microamps describes a microcurrent device whatever the marketing calls it, and a figure in milliamps describes a device built to reach muscle.
3. The measurement conditions
Output is measured into a fixed resistance in a laboratory, commonly 500 ohms, rather than into your face.
So a specification saying up to 7 milliamps at 500 ohms is being straight with you, and a bare number with no conditions is claiming more than it can support.
4. Whether the frequency moves
A fixed signal repeats, and a muscle given the same signal for ten minutes gets used to it while your nerves do the same, so the session fades even though the output has not changed.
Ask whether the frequency holds at one value or changes during the session, and whether the brand explains how, since a published range printed without explanation is not the same as a moving signal.
Pooling 22 studies, researchers found that stimulation which keeps changing produced more evoked force with less fatigue than a fixed pattern (Cavalcante 2026), though not every study agrees (Papaiordanidou 2014).
5. The regulatory record
FDA cleared and FDA approved are different, and consumer facial devices are cleared rather than approved.
A genuine clearance comes with a record number beginning with K that you can look up in the FDA's public database in about two minutes.
A brand claiming clearance without publishing a number is asking for trust it has not earned, and one claiming approval for a facial toning device is describing a pathway it almost certainly did not use.
6. What it needs to run
Every electrical facial device needs a conductive medium, and whether you can choose it is a real difference between brands.
FOREO states BEAR 2 must be used with a conductive serum and publishes its own at $59, and NuFACE publishes replacement gel from $35.
Add twelve months of gel to each sticker price before comparing, because that is what you will actually pay.
7. The session, and whether you will do it
Ask how long a session is and how often it is meant to happen, then be honest with yourself about whether that fits your life.
The research timeline runs to twelve weeks, so a device you abandon in week three has failed whatever its specification said.
A longer advertised routine is not a bigger dose, and it is often a sign a device needs longer to do less.
8. What is missing from the page
A blank field is information, since a brand confident in its number publishes the number.
When you meet a missing specification, record it as undisclosed rather than filling it in from the price, the packaging or how strong the device feels.
9. The contraindications
Anyone with a pacemaker or another implanted electronic device, anyone pregnant, and anyone with epilepsy or a seizure disorder should not use these devices at all.
Metal implants in the treatment area, active skin conditions and recent facial procedures all need a clinician's guidance first.
A brand that buries or omits this list is telling you something about its priorities.
10. The mirror test
If you can try the device, watch the mirror rather than your nerves.
A visible contraction means the current crossed the motor threshold, and no marketing can write around a muscle that does not move.
A sharp sensation is not the same thing, since concentrated current at the surface through poor contact stings while delivering less.
What to ignore
Mode counts, unless each mode is explained by what it physically does differently.
Before and after photographs, which vary with lighting, angle, expression and time of day far more than with any device.
Claims of permanent results, since muscle tone is maintained by continued use in every case.
Any head-to-head superiority claim, because no randomised trial has compared consumer facial devices against each other, ours included.
Running the checklist on our own line
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.
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.
PDM moves the signal across 361 frequency points between 1,370 and 1,730 Hz so it does not repeat, and it varies frequency only, leaving amplitude where you set it.
The session is three minutes on each side of the face, about ten minutes including the Infuse pass.
Any water-based conductive serum works, so there is no required subscription.
The clearance records are K190269 for Face, K230506 for Pro and Pro Edition, K221443 for Pro Plus + and K243587 for GLOW, and all five are made in Japan in an ISO 13485 facility.
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.

Competitor prices verified on 9 September 2026 against published product pages. PureLift figures verified 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.
Two related questions come up often alongside this one, and we have answered both in full: what we would tell you not to buy, and which device is actually the strongest.
