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.

Use both, on different nights or at different ends of the day, and never apply a retinoid as the conductive layer for a session.
This article sets out what to check before you start, such as:
- why a retinoid is the wrong conductive layer
- what a compromised barrier does to a session
- the two schedules that work
- how to introduce one without confusing the other
- the signs you are doing too much
and many more!
A retinoid does more for your skin than any device in this category does, so protect the retinoid routine first.
Key Points:
Never use a retinoid as the conductive medium; it is not formulated to carry current and it drives active ingredient into skin in a way nobody has tested.
A retinoid thins the stratum corneum while your skin adjusts, which lowers resistance and makes a familiar level sting.
Alternate nights is the simplest schedule, with the device on one night and the retinoid on the next.
Morning device and evening retinoid is the other workable schedule, and it suits people who prefer a consistent daily routine.
Introduce one at a time, four to six weeks apart, so you can tell which is causing what.
Why a retinoid is the wrong conductive layer
A conductive medium needs to be water-based, generous and wet enough to carry current across the whole contact area.
Retinoid formulations are built to deliver an active ingredient slowly into skin, often in an emollient or encapsulated base, which is close to the opposite of what conduction needs.
Beyond the poor conduction, there is a second problem: iontophoresis and electroporation are specifically designed to increase delivery of what sits on the skin, and nobody has studied what increased retinoid penetration does.
We have never tested it, no brand has published on it, and that is reason enough not to use your tretinoin as a gel.
What a compromised barrier does to a session
Retinoids speed cell turnover, and while your skin adjusts the outer layer is thinner and more permeable than usual.
Thinner skin means lower electrical resistance, so the same setting on the dial delivers a stronger sensation than it did last week.
People read that as the device getting stronger or their skin getting sensitive, and the real cause is the retinoid doing exactly what it is supposed to do.
Stinging in that situation is a barrier signal rather than a current problem, which we cover in our article on stinging.
The two schedules that work
Alternate nights. Device on Monday, retinoid Tuesday, device Wednesday, and so on. Both get four sessions a week, neither compounds the other.
Morning and evening split. Device in the morning with a plain conductive gel, retinoid at night as usual. This suits people who want the depuffing effect before work anyway.
Whichever you choose, keep the conductive gel simple, with no acids, no vitamin C at low pH, no alcohol and no fragrance.
Moisturizer and sunscreen go on after the session, never before, because both interfere with contact.
Introducing one without confusing the other
If you already use a retinoid and are adding a device, keep the retinoid exactly as it is and start the device at a low level on alternate nights.
If you already use a device and are adding a retinoid, start the retinoid twice a week and expect to drop your device level for a few weeks while your skin adjusts.
If you are starting both, start one, wait four to six weeks until it is settled, then add the other.
Starting both at once is how people end up unable to tell whether the redness is the retinoid, the device, or the two together.
The signs you are doing too much
Redness that is still there the next morning, rather than settling within the hour.
Tightness, flaking around the mouth and nose, or a stinging reaction to products that never stung before.
A session that feels sharp at a level that was comfortable a fortnight ago.
In all three cases, stop the device for a week, keep the retinoid, and restore the barrier with a plain moisturizer before restarting at a lower level.
Which one to protect if you have to choose
The retinoid. It has decades of human biopsy evidence for dermal collagen change, which is more than this entire device category can claim, and we say so in our collagen article.
A device works on the muscle layer and on how your face looks the same day, which is a different job rather than a competing one.
Running both well, on separate schedules, gets you both results.
Running both badly, in the same session, usually costs you the retinoid routine, which is the more valuable of the two. The full technology map is in our category overview.
