Read bio
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.

Muscle adapts during recovery rather than during the work, which is why a session is the stimulus and the days between are where the change happens.
This article explains what is actually happening, such as:
- Where the adaptation happens
- Why more sessions is a tempting mistake
- The skin side of recovery
- What the right schedule looks like
- The signs you are overdoing it
and many more!
That is unintuitive if you are used to thinking of skincare as something where more application means more effect.
Key Points:
Four or five sessions a week is a sensible target; seven is not better.
Three minutes per side is the maximum on any PureLift model and the ten minute session ends itself.
Running longer or higher does not accelerate anything and is outside what the device was cleared for.
Skin needs recovery too, and the barrier is the part that complains first.
Persistent soreness or a face that feels tired is a reason to take two days off.
Where the adaptation happens
A contraction is a stimulus. It tells the muscle that more capacity would be useful, and the building happens afterwards, during rest, the way it does anywhere else in the body.
Remove the rest and you are repeatedly applying the stimulus to tissue that has not finished responding to the last one. That is not more progress, it is interrupted progress.
Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness over 12 weeks of motor-level facial stimulation (10.1111/jocd.12007), under a defined protocol rather than an open-ended one, and the protocol is the point.
Why more sessions is a tempting mistake
Skincare trains people to think in terms of application: more sunscreen is better than less, twice a day beats once.
Muscle work is not like that. It behaves like exercise, where the schedule matters as much as the effort and where somebody training a muscle group daily with no rest is doing worse than somebody training it three times a week.
The other tempting mistake is doing extra after a missed week. The muscle does not bank work, and compensating does not exist as a mechanism.
The skin side of recovery
The face is not only muscle. Ten minutes of probe contact plus a product worked in thoroughly is a demand on the barrier, and daily sessions multiply it.
Skin that starts stinging when you apply things, feels tight all day, or develops new reactivity is telling you the barrier is behind, and the answer is days off rather than a gentler serum.
People with reactive skin often do better at three sessions a week than at five, and the outcome over three months is not worse.
What the right schedule looks like
Four or five sessions a week, with the rest days spread rather than clustered, is a sensible default.
Three a week is a perfectly good schedule if that is what you will keep, and a schedule you keep beats an ambitious one you abandon in March.
Ten minutes per session, three minutes per side maximum, at a level you can hold comfortably. The device ends the session itself, which is a design decision rather than a suggestion.
Do not run two sessions in a day, and do not go back over an area because it felt like it needed more.
The signs you are overdoing it
Soreness in the facial muscles that persists rather than settling. Mild soreness in the first week of a new routine is normal; soreness in week six is not.
Skin that has become reactive, tight or flaky since you started.
A face that looks tired rather than fresher after sessions.
Dread. If you are talking yourself into the session, the level is too high or the frequency is too much, and both are worth reducing before the whole routine collapses.
What a rest day is not
It is not lost ground. Deconditioning is gradual, measured in weeks rather than days, so a day or two off costs nothing.
It is not a reason to do a longer session tomorrow.
And a rest day from the muscle work does not rule out a light drainage pass if you want one, since that is a different mechanism with a same-day effect; on PureLift, levels 1 and 2 are nanocurrent and microcurrent and contract nothing.
The wider point
This is a routine you want running for years, and years are built out of sustainable weeks.
The person doing four sessions a week in March beats the person who did seven in January, every time, and that is the only comparison that matters at the end of a season.
For the timeline, see when to expect visible results, and for the habit, a 90-day routine that survives February.
