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.

Six things account for almost every case of a device that seems not to be doing anything.
This article walks through the routine step by step, such as:
- One, not enough weeks
- Two, the serum dried
- Three, the level is too low to be doing anything
- Four, the placement is wrong
- Five, the expectation does not match the mechanism
and many more!
Work through them in order rather than concluding the device is faulty.
Key Points:
The research protocols ran 12 weeks, so judging at week three is judging too early.
Dry serum is the most common single cause of a session doing less than it should.
If the muscle is not visibly contracting, you are below level 3 and not doing EMS at all.
Daily mirror checks measure sleep and salt, not progress.
Volume loss and dermal laxity are not muscle problems and no device fixes them.
One, not enough weeks
Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness across 108 women, and the protocol ran for 12 weeks (10.1111/jocd.12007). Chang and colleagues ran a double-blind sham-controlled trial over a comparable span (10.3390/ijerph17113783).
Twelve weeks is the honest figure and most people evaluate at three. Give it a full season before deciding.
Consistency matters more than intensity across those weeks; four sessions a week at a comfortable level beats two punishing ones.
Two, the serum dried
Current needs a wet path, and skin dries faster than people expect, especially around the jaw and in a heated room. When a patch dries, resistance rises there and the current concentrates where the skin is still damp.
If the probe starts to feel sticky rather than smooth, reapply immediately. Do not climb the dial to compensate, because the extra current goes to the wrong places.
Use a fluid water-based serum. Oils and thick creams do not conduct, and plain water evaporates within a minute.
Three, the level is too low to be doing anything
On PureLift, levels 1 and 2 are nanocurrent and microcurrent and do not contract a muscle at all. If you have been sitting at level 2 expecting contour change, the device has been working correctly and you have been using the wrong band.
Level 3 is where the motor threshold is crossed. The check is visual: look in the mirror and see whether the muscle moves. If nothing moves, you are not doing EMS.
Move up one level at a time and stay where you can hold it comfortably; a level you dread is a level you will skip.
Four, the placement is wrong
Current goes where the probe is. A technically perfect session over the wrong area works the wrong muscle.
Work upward and outward, from the jaw toward the ear and from the corner of the mouth toward the cheekbone, following the direction the tissue has drifted away from. Do not drag downward.
Slow down. Most people move the probe faster than the contraction cycle needs, which means the muscle never completes a full contraction anywhere.
Five, the expectation does not match the mechanism
EMS works muscle. It does not replace volume, and if your cheek has hollowed, the missing thing is fat rather than tone; fillers address that and current does not.
It does not thicken the dermis or tighten skin the way heat-based clinic treatments aim to, because electrical stimulation does not heat tissue.
It does not reposition the SMAS, which is what a surgical facelift does.
If what is bothering you sits in one of those three categories, no amount of correct technique will produce the change, and the honest answer is a different intervention.
Six, you are measuring wrong
Checking the mirror daily measures how much salt you ate and how well you slept. Muscle thickness does not move on that timescale.
Photograph monthly instead, in the same light, at the same distance, with the same expression and head position. Morning, before the day changes your face.
A single photograph from before you started, taken in a different light with a different expression, is worse than no photograph, since it invites a comparison that proves nothing either way.
The order to work through
Fix the serum first, since it is free. Check for visible contraction second. Correct the placement and slow down third.
Then commit to twelve weeks and photograph monthly, and only after that decide whether the change you want is one this category produces.
Three minutes per side is the maximum on any PureLift model, and the ten minute session ends on its own; running longer is not a fix for anything on this list.
