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.

Dr. Bertica M. Rubio is a board-certified physician and Medical Director of the Antiaging Regenerative Medicine Clinic in Redlands, California. She earned her Doctor of Medicine from Dartmouth Medical School and completed her pediatrics residency at UC Irvine Medical Center.
With decades of clinical experience, she specialises in age management medicine, regenerative medicine, wound healing and growth factor therapies, and her practice integrates evidence-based medical science with advanced aesthetic treatment.
For PureLift LAB she reviews articles for medical accuracy across the whole dial, from the gentle nanocurrent and microcurrent settings through to muscle-level EMS and the Infuse pass.

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.

Microcurrent is used clinically for wound healing and pain, in sports for recovery, and cosmetically for facial toning, and a consumer facial device is cleared only for the last of those.
This article sets out what to check before you start, such as:
- the four main uses and who performs them
- which use has the longest research history
- why sports research does not transfer to faces
- what a facial device is and is not cleared to do
- why you should not self-treat a medical problem with a beauty device
and many more!
The same word covers a wound care treatment and a beauty routine, and keeping them apart protects you from claims that belong to the other one.
Key Points:
Clinical microcurrent is used for wound healing, pressure injuries, burns and some pain conditions, delivered by clinicians with medical devices.
Sports and exercise research has explored recovery, strength and body composition, mostly in limbs and often alongside training.
Cosmetic microcurrent targets facial muscle tone and skin appearance, and consumer devices are cleared for cosmetic facial stimulation only.
Reviewers describe the clinical evidence as promising but inconsistent, with small studies and poorly standardized protocols.
A facial beauty device should never be used to treat a wound, nerve condition or pain problem, which belong with a clinician.
Wound healing and tissue repair
This is the oldest clinical use and the one with the longest research thread, going back to studies in the late 1960s on skin ulcers.
Clinicians use microcurrent and related low-intensity currents on chronic wounds, pressure injuries and burns, as an addition to standard wound care rather than a replacement for it.
Jonik and colleagues in 2025, a 2025 narrative review, covers these uses and notes the familiar limitations: small samples, limited controls, and treatment parameters that vary from study to study.
None of that is relevant to a facial device, and you should never use a beauty device on an open wound, broken skin or a healing surgical site.
Pain management
Musculoskeletal and nerve pain
Microcurrent has been studied for musculoskeletal pain, neuropathic pain and conditions such as fibromyalgia, usually delivered under clinical supervision.
Results across this literature are mixed, and the same review describes the evidence as inconsistent.
Microcurrent operates far below the levels used by TENS, which is the more common electrical pain device, explained in our comparison with TENS.
Cranial stimulation
A related approach, cranial electrotherapy stimulation, applies small currents across the head and has been studied for anxiety, depression and insomnia.
That review reports adverse effects such as headache, skin irritation or dizziness in under one percent of patients in that context.
It is a medical intervention with its own devices and its own clearances, and it has nothing to do with facial toning.
Sports and exercise recovery
Kolimechkov and colleagues in 2023 reviewed microcurrent combined with exercise in healthy, active people, covering strength, recovery and body composition.
Some small trials reported modest acute strength improvements, others found no benefit for muscle soreness, and much of the mechanism work was done in animals.
The authors' central limitation is that protocols vary so widely that optimal settings cannot be identified.
Because this research studied limbs, often alongside training, it does not tell you anything directly about your face, which is a point we make in our article on the research.
Facial aesthetics
What the cosmetic use is
Cosmetic microcurrent and the related EMS technology aim to tone facial muscle and improve skin appearance over weeks of regular use.
Consumer devices in this category are FDA cleared for cosmetic facial stimulation, which is the whole of what the clearance covers.
Cleared is not the same as approved, a difference explained in our article on FDA clearance.
What the evidence shows
The facial trials are small, mostly around twelve weeks, and report increased cheek muscle thickness and improved skin appearance measures.
No trial has measured facial collagen by biopsy, facial fat, or lymph flow, so those claims remain unmeasured.
What results to expect and when is set out in our timeline article.
Why a facial device is not a medical device
The same physics can sit inside a clinical wound care device and a consumer facial device, and the two are cleared for completely different purposes.
A facial device's clearance does not extend to pain, nerve conditions, wounds or any medical use, even when the underlying technology overlaps.
Using a beauty device to self-treat facial nerve weakness, jaw pain or a slow-healing wound risks delaying care you actually need.
Facial nerve symptoms in particular belong with a doctor, covered in our nerve safety article, and jaw pain with a dentist, covered in our TMJ article.
How to read a claim that crosses the line
If a facial device brand cites wound healing research, it is borrowing evidence from a different use with different devices and different tissue.
If it cites sports research, it is borrowing evidence from limbs and training contexts.
If it cites cellular energy, it is usually citing a 1982 rat skin study, traced in our ATP article.
The honest facial claim is narrow: modest muscle and skin appearance changes over about twelve weeks, maintained while you keep going.
Frequently asked questions
What is microcurrent therapy used for medically
Clinically it is used mainly for wound healing, pressure injuries, burns and some pain conditions, delivered by clinicians as an addition to standard care.
Is microcurrent therapy the same as a microcurrent facial
The underlying technology overlaps, but clinical devices and consumer facial devices are cleared for different purposes. A facial device is cleared for cosmetic facial stimulation only.
Can a microcurrent facial device help with pain
Consumer facial devices are not cleared for pain. Pain conditions should be assessed by a clinician rather than self-treated with a beauty device.
Does microcurrent help muscle recovery after exercise
Some small studies report modest benefits and others report none. Reviewers describe the protocols as too inconsistent to identify reliable settings.
Is microcurrent therapy safe
The reviews ranking for this question report very low rates of adverse effects in clinical contexts. Consumer facial devices have their own exclusions, including pacemakers and implanted electronic devices.
