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.

Microcurrent facials are considered low risk for most healthy adults, and a short list of people should not have one at all.
This article sets out what to check before you start, such as:
- who should not have a microcurrent facial under any circumstances
- who should ask a doctor first rather than simply proceeding
- what an FDA clearance does and does not promise about safety
- why the current level is not the main safety question
- what to ask a salon before you book
and many more!
If you have any implanted electronic device, stop here and speak to your doctor rather than to a brand.
Key Points:
Do not use microcurrent or EMS if you have a pacemaker, implanted defibrillator or any other implanted electronic device.
Ask your doctor first if you are pregnant, have epilepsy, a heart condition, or an active cancer diagnosis.
Avoid the front of the neck over the thyroid, which is standard practice across the professional world.
An FDA clearance is a finding of equivalence to an existing device rather than proof that a device is safe for you specifically.
Reported problems in the dermatology literature are mild and self-limiting, mostly irritation and transient redness.
The absolute exclusions
An implanted electronic device is the one true stop. Pacemakers, implanted defibrillators, neurostimulators and cochlear implants all sit in this group, because applied current can interfere with them.
No brand should be reassuring you around that, ours included, and the right conversation is with the clinician who manages the implant.
Broken skin, active infection, and an area recently treated with a professional procedure should be left alone until healed.
If you are under eighteen, these devices are not designed or tested for you.
The ask-first group
Pregnancy is not a documented hazard for facial microcurrent, and it is also not studied, so the honest position is to ask your obstetrician rather than assume.
Epilepsy, because applied electrical current is a reasonable thing to discuss with a neurologist first.
A heart condition or an arrhythmia, for the same reason.
An active cancer diagnosis or treatment, where any new therapy belongs in the conversation with your oncologist.
Metal implants and dermal fillers, which we cover in more detail in a separate article.
The thyroid question
Professional practice avoids running current over the front of the neck where the thyroid sits, and reputable training courses teach that boundary.
The evidence for harm is thin, and the reasoning is precautionary, which is a sensible way to treat an endocrine organ close to the skin.
If you have a thyroid condition, that is a reason to ask your doctor and to keep the device off the front of the neck entirely.
Working the jawline and under the chin is a different area and is not the same question.
What a clearance means for safety
An FDA 510(k) clearance means the manufacturer showed the device is substantially equivalent to one already on the market.
It involves electrical safety testing to recognised standards, which is genuinely worth something.
It is not a finding that the device works, and it is not a judgement about whether the device is safe for your particular medical situation.
We have written a full guide to checking any brand's clearance yourself, which takes about two minutes.
PureLift devices are cleared under K190269, K230506, K221443 and K243587.
Why level is not the main question
People assume the safety question is how strong the device is, and in practice the common problems come from contact rather than intensity.
A dry conductive layer concentrates current into a small area, which is uncomfortable and is also where irritation comes from.
Using enough water-based serum matters more for a comfortable session than choosing a lower setting.
Pain is always a signal to stop and reset rather than to push through.
What to ask a salon
Which device they use and whether it carries a clearance you can look up.
Whether the therapist is trained on that specific machine rather than on microcurrent generally.
How they handle the thyroid area and the eye area.
Whether they will run a patch test if your skin is reactive.
A good salon will answer all four without hesitating.
This comparison sits inside our full map of the category, where we set out all 33 devices we track, what each one carries and what each brand publishes: Nine Technologies on One Dial, What the Rest of the Market Actually Carries.
