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.

Nobody has run a study comparing morning with evening facial stimulation, so anyone telling you one is better is guessing.
This article compares the two on what decides the result you actually see, such as:
- What the clock genuinely changes
- What the clock does not change
- Pick the slot you will keep
- The case against alternating
- If you want to compare for yourself
and many more!
The second one is the one that decides your result.
Key Points:
Morning is when fluid has pooled overnight, so a drainage-focused session has the most visible effect then.
Evening suits people who want unhurried time and are pairing the session with serums they apply at night.
The session is ten minutes and ends on its own, and three minutes per side is the maximum on any PureLift model.
Whichever you pick, the device does the same thing at the same level regardless of the hour.
Alternating between the two is the one choice that reliably goes wrong, because a habit with no fixed slot stops being a habit.
What the clock genuinely changes
Overnight, fluid settles in the face because you have been horizontal for seven hours. A morning session that emphasises drainage strokes is therefore working on something that is measurably there, and the visible difference in the mirror at 7 am is larger than the same session produces at 9 pm.
That is a same-day appearance effect and it fades. It is not the reason to buy a device and it should not be mistaken for the cumulative work.
The second real difference is glide. If you cleanse in the evening and layer serums afterwards, an evening session slots into a routine you already have, and the serum is already in your hand. Morning users often have to add a step.
What the clock does not change
The current is identical. Level 2 delivers the same nanocurrent and microcurrent at either hour, and level 6 crosses the motor threshold and contracts the muscle at either hour. PDM cycles through the same 361 frequency points between 1,370 and 1,730 Hz whenever you switch the device on.
There is no circadian mechanism in the published facial stimulation literature that would make muscle respond differently at breakfast than at bedtime. If somebody claims one, ask which study, and expect the question to end the conversation.
Pick the slot you will keep
Adherence is the variable that actually separates people who see a change from people who do not. Kavanagh and colleagues ran their trial over 12 weeks and measured an 18.6 percent increase in cheek muscle thickness at the end of it (10.1111/jocd.12007); the interesting number there is 12 weeks, because that is how long the participants kept turning up.
So the real test is unglamorous: at which hour will you still be doing this in March? If your mornings are chaotic, evening. If you are asleep by nine, morning. Answer honestly and the timing question is finished.
The case against alternating
Alternating sounds flexible and behaves like an absence of a decision. A habit needs a fixed cue, and when the cue moves it stops firing; people who alternate tend to describe a first fortnight of enthusiasm followed by a device in a drawer.
Pick one and let it attach to something you already do every day without thinking, cleansing, coffee, brushing your teeth.
If you want to compare for yourself
Hold everything constant except the hour: same lighting, same camera distance, same expression, same head position, same level, same serum, same interval between the session and the photograph. Change only the time of day.
That will not produce evidence, and one photograph never does, but it will stop you drawing conclusions from a window that happened to be brighter.
Practical notes either way
Use a water-based serum for conductivity and glide, and keep the skin damp throughout; a session that starts to drag is a session with a dry patch, not a session that needs more power.
Ten minutes is the session and the device ends it for you. Three minutes per side is the maximum on every PureLift model.
Sit at a level you can hold comfortably rather than the highest you can tolerate; the muscle does not respond better to being punished, and a level you dread is a level you will skip.
For the mechanism behind the contraction, see the contraction and relaxation cycle, and for the morning drainage case see the depuffing ritual.
Two related questions come up often alongside this one, and we have answered both in full: how often to use one, and whether daily use makes sense.
