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.

Mild tingling, a metallic taste and brief redness are ordinary; pain, lasting redness and headache are not, and nearly all of the unpleasant experiences come down to contact rather than intensity.
This article sets out what to check before you start, such as:
- what sensations are expected and why they happen
- the reactions that mean stop rather than adjust
- who should not use a microcurrent device at all
- why headaches and jaw aching usually mean technique
- what the published adverse event reporting actually shows
and many more!
Nothing in a facial session is worth pushing through, because the result comes from consistency rather than intensity.
Key Points:
Expected: mild tingling, a metallic taste near the jaw, brief warmth and redness that fades within an hour.
Not expected: pain, redness lasting into the next day, headache, persistent eyelid twitching or any sensation like a shock.
Do not use a microcurrent or EMS device over an implanted electronic device such as a pacemaker, and speak to your doctor first if you are pregnant or have epilepsy.
Avoid the thyroid region on the front of the neck, which is standard advice across the professional world.
Most unpleasant sessions are a dry or thin conductive layer rather than a device problem.
The ordinary sensations
A mild tingling or fizzing under the probes is the current doing what it is supposed to do.
A metallic taste near the jaw at higher levels is ordinary and harmless, caused by current passing close to the nerves that carry taste.
Brief warmth and a flush of colour that settles within an hour is increased circulation rather than irritation.
At motor-level settings on an EMS device you will also see and feel the muscle contract, which is the point rather than a side effect.
The ones that mean stop
Pain, at any level. A session should feel like firm pulling, never pricking or burning.
Redness that is still there the next day, which suggests irritation rather than circulation.
Headache during or after a session, which is usually too high a level around the temples or working over a clenched jaw.
Eyelid twitching that continues after you have moved on from the eye area.
Anything you would describe as a shock rather than a pull, which usually means broken contact and should be investigated before you continue.
Why most bad sessions are contact
Current follows the path of least resistance, so a dry patch concentrates it into a small area, and that concentration is the sting.
The same total output arriving through a tenth of the contact area feels roughly ten times more intense, which is why turning the level down treats the symptom rather than the cause.
The fix is more conductive serum, reapplied between sides, with skin visibly wet rather than dewy.
We have written this out in full in why a session feels sharp.
Who should not use one
Anyone with a pacemaker, implanted defibrillator or other implanted electronic device should not use a microcurrent or EMS facial device.
Speak to your doctor first if you are pregnant, have epilepsy, or have a heart condition.
Avoid the front of the neck over the thyroid, which is standard professional practice.
Do not treat over broken skin, active infection, sunburn or an area recently treated with a professional procedure.
If you have had injectables, leave the spacing your practitioner advises, which we cover separately.
What the reporting shows
Adverse events associated with at-home microcurrent devices have been reviewed in the dermatology literature, and the pattern is mild and self-limiting rather than serious.
The common complaints are irritation, transient erythema and discomfort, which maps closely onto contact and technique.
That is reassuring and it is not a reason to be casual, particularly with the contraindications above.
Anyone with a medical condition should ask their own doctor rather than take a brand's word, ours included.
Reducing the odds of a bad session
Use enough conductive serum that skin looks wet for the full pass, and reapply between sides.
Build your level over weeks rather than starting at the top.
Keep to ten minutes, three minutes per side maximum, since longer does not improve the result.
Clean the probes after every session so contact stays even.
Stop for the day if a session is uncomfortable after you have added serum and lowered the level.
