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.

The diamond-faceted probe was introduced with the 2019 design refresh, and its job is a practical one, steadier skin contact and controlled glide across the curves of the face.
This article covers what actually decides the answer, such as:
- Why the contact interface is worth engineering
- What actually determines current at the skin
- Which models carry the design
- How the probe relates to PDM
- The conductive medium does more than you think
and many more!
That is a real engineering role, and it is not the same as proving the shape spreads current more evenly than a round probe, which is a claim we do not have the bench data to make.
Key Points:
The documented purpose of the faceted surface is contact and glide, not a superior current pattern.
There is no comparative current-density map, no fibre-recruitment study, and no head-to-head bench test in the technical record, so we do not assert one.
Current at the skin is set by output, contact area, skin impedance, conductive medium, pressure and placement, with probe geometry as one input among several.
The diamond-faceted probe is part of the PureLift Pro Plus and PureLift GLOW feature set rather than a line-wide feature.
Every PureLift device is built in Japan in facilities operating to ISO 13485 and carries FDA 510(k) Class II clearance.
Why the contact interface is worth engineering
Electrical stimulation depends on a complete path, from the device through the probe, through a conductive medium, into the skin and back again.
When contact goes inconsistent the session stops feeling predictable, sensation flickers, and most people respond by stopping mid-stroke to reposition the head, which breaks the rhythm the routine depends on.
The face is not a flat surface, the jawline, the cheek, the forehead and the area around the mouth each present a different curve and a different working angle.
A faceted surface gives you defined edges and orientations to work with as you cross those curves, which is a handling benefit you can feel rather than a physiological outcome you have to take on trust.
What actually determines current at the skin
Current density is simply the amount of current passing through a given area, and in real use it shifts with total output, electrode geometry, contact area, skin impedance, the conductive medium, how hard you press, where you place the probe and the waveform being delivered.
Change any one of those and the electrical conditions at the interface change with it, which is why probe shape on its own predicts very little about how a device performs on a given face.
A diagram of a diamond next to a circle establishes nothing about living tissue, and a defensible comparison would need controlled measurements at a defined output, identical media, consistent pressure and a repeatable test surface, then a demonstrated link between the measurement and facial use.
That work has not been done, so this article does not claim a broader, flatter, more uniform or more muscle-matched distribution from the diamond shape, and you should be sceptical of any brand that claims it without publishing the test.
Which models carry the design
The diamond-faceted probe belongs to the PureLift Pro Plus and PureLift GLOW feature set, and it should not be described as a feature of all five models.
Both of those models run up to 9 mA, the highest output in the range, and GLOW adds dual-wavelength LED at 634 nm red and 465 nm blue, usable separately or together.
The rest of the electrical picture is shared across the line, every PureLift device runs nanocurrent at level one, microcurrent at level two, EMS from level three upward, and Infuse for electroporation-assisted serum delivery.
Keeping contact hardware separate from the electrical engine matters, because a probe shape and a current capability are different things and conflating them is how spec sheets start misleading people.
How the probe relates to PDM
PDM is the waveform-delivery architecture used across the PureLift range, and it varies frequency continuously across 361 points between 1,370 and 1,730 Hz.
Frequency is the only thing PDM varies, amplitude and pulse duration stay where you set them, which is worth stating plainly because the literature on modulated stimulation is about frequency variation and nothing else.
Varied-frequency stimulation is supported in general terms as a way to delay the onset of fatigue during a session, and that support is category-level rather than specific to any brand implementation.
The probe is simply where that signal meets the skin, it does not create PDM, does not raise the device maximum current, and does not decide which tissue responds.
The conductive medium does more than you think
A water-based conductive medium is part of the working interface, not an optional extra, and running a probe on dry skin gives you patchy contact and an uneven sensation regardless of how the probe is shaped.
Oil-based products work against you here, oil is a poor conductor and will break the path the current needs.
Reapply when the surface starts to drag, since a session where the probe glides freely is doing more for you than one where you are pushing harder to compensate for a drying medium.
Using the probe well
Keep the full contact surface on the skin rather than working on an edge, and let the facets follow the contour instead of forcing the head flat against a curve.
Light, steady pressure beats heavy pressure, since pressing harder does not increase output and mainly costs you comfort and glide.
Three minutes per side is the maximum on every model, roughly ten minutes for a full session once Infuse is included, and a slow, continuous pass covers a side comfortably within that time.
The probe is good hardware doing an honest job, and describing that job accurately is more useful to you than a physics claim nobody has measured.
Two related questions come up often alongside this one, and we have answered both in full: the procedure in full, and the step by step method.
