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.

Working muscles do move fluid around the body, and that is a long way from the drainage claims made for facial devices, so this sets out what is actually known.
This article stays inside the evidence, such as:
- What muscle activity does to circulation generally
- Why the face is a different case from the legs
- What has and has not been measured on a face
- Why we avoid the word drainage
- What you can honestly expect to see
and many more!
By the end you will know where the science stops and the marketing starts.
Key Points:
Contracting muscles compress the vessels running through them and releasing lets blood move again, which is a real mechanism.
That mechanism is best documented in large muscles doing sustained work, not in small facial muscles over ten minutes.
No consumer facial device has been shown to clear a measured volume of fluid.
So we describe a face that looks less puffy, which is accurate, rather than drainage, which is not established.
Lymphatic drainage as a medical treatment is a clinical procedure and not what a home routine performs.
The claim that a facial device moves fluid sits somewhere between a real physiological mechanism and a marketing invention, which makes it worth taking apart carefully.
What muscle activity does to circulation
A contracting muscle compresses the small vessels running through it, and when it releases, blood moves through again.
Repeat that cycle and you get a pumping effect, which is a well-established mechanism and the reason walking helps circulation in the legs more than standing still does.
That is genuine physiology rather than something a brand invented, and it is the honest starting point for this conversation.
Why the face is a different case
The evidence for muscle activity assisting fluid movement is strongest in large muscles doing sustained work against gravity, which is not what facial muscles are or do.
Facial muscles are small, they attach to skin rather than bone at one end, and a session lasts ten minutes rather than an hour.
Gravity is also already doing most of the work on your face once you are upright, which is why morning puffiness resolves on its own by mid-morning whether or not you do anything.
So carrying a leg-muscle mechanism across to a face is an inference rather than a finding, and we would rather flag that than lean on it.
What has been measured on a face
The facial research that exists measured muscle thickness and cosmetic appearance rather than fluid volume.
In the largest facial trial of its kind, 108 women used daily muscle stimulation for twelve weeks and ultrasound measured an 18.6 percent increase in cheek-muscle thickness, with a clear difference from the untreated group at six weeks (Kavanagh 2012), and a double-blind sham-controlled trial in adults over 65 found muscle thickness and bite force increased after six weeks (Chang 2020).
An eight-week split-face trial reported cosmetic and blood-flow improvements, and because it combined facial stimulation with iontophoresis, LED and cooling in one device, it cannot say what any one of them contributed (Omatsu 2024).
Those are category studies run with their own devices, and none of them measured fluid clearance from a face.
Why we avoid the word drainage
Lymphatic drainage in the medical sense is a clinical treatment for specific conditions, performed by trained practitioners over sustained courses.
Using the same phrase for a ten-minute routine borrows the authority of that treatment without having earned it.
Detox is worse, since the word has no defined meaning in this context at all.
No consumer facial device has been shown to clear a measured volume of anything, so a brand claiming it is describing a study nobody has run.
We would rather lose the word than misuse it.
What you can honestly expect
Your face looks fresher and less swollen within minutes of a session, and that effect holds best for the first few hours.
Some of that is circulation from the muscle work, some is the movement and contact of the device itself, and some is that you are now upright and awake.
Separating those contributions is not something anyone has done, so the honest description covers the outcome rather than the mechanism.
That description is enough, because a face that looks less puffy is what people actually wanted.
What is not a fluid question
Softening along the jaw and a cheek losing its shape are muscle tone rather than fluid, and they change over weeks rather than minutes.
A cheek that has genuinely emptied is fat, which is filler territory.
Persistent swelling is a medical question, so anything sudden, painful, one-sided or unresolving belongs with a clinician rather than with a routine.
The same applies to swelling after a new medication, a dental procedure or an insect bite.
What actually helps morning puffiness
Being upright and moving, which does most of it on its own.
Sleeping with your head slightly raised, which reduces how much settles overnight in the first place.
Watching salt and alcohol the night before, since both reliably show up on a face the next morning.
A session that adds movement, contact and muscle work, which brings the same result forward by an hour or two.
Cold, which constricts vessels temporarily and is genuinely effective and genuinely short-lived.
Model notes
All five PureLift models run nanocurrent at level 1, microcurrent at level 2, EMS from level 3 to 10, and Infuse as a second pass, and the contraction cycle described here happens from level 3 upwards.
The session is three minutes on each side of the face at a level where you can see the muscle answer, followed by the Infuse pass, about ten minutes in total.
Face at $499 and Pro at $699 reach up to 7 milliamps, Pro Edition at $799 reaches up to 7.7, and Pro Plus + at $899 and GLOW at $999 reach up to 9, all measured at 500 ohms and always written as up to.
GLOW alone adds light, red at 634 nm cleared for the treatment of wrinkles, blue at 465 nm cleared for mild-to-moderate inflammatory acne, and purple, which is red and blue running together.
Every model is cleared through the FDA 510(k) pathway, under records K190269 for Face, K230506 for Pro and Pro Edition, K221443 for Pro Plus + and K243587 for GLOW, and all five are made in Japan in an ISO 13485 facility.
Anyone with a pacemaker or another implanted electronic device, anyone pregnant, and anyone with epilepsy or a seizure disorder should not use the device at all.
For the practical morning routine, read how to depuff your face, and for the muscle cycle, read the contraction-relaxation cycle.
Model figures verified on 9 September 2026 against the PureLift LAB store and FDA records K190269, K230506, K221443 and K243587. Every model runs nanocurrent, microcurrent, EMS and Infuse; consumer copy always says up to. This article is general cosmetic information and is not medical advice.
Two related questions come up often alongside this one, and we have answered both in full: whether microcurrent and EMS are the same thing, and which muscles a session actually reaches.
