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.

Five devices in this category say one thing to the regulator and a different thing to you, and in each case the filing is the more reliable document.
This article covers what actually decides the answer, such as:
- a cooling function cleared to soothe and sold as tightening
- a laser cleared for the eye area and marketed for neck and chest
- a brand whose own FAQ contradicts its own product page
- an irradiance split that differs between page and filing
- how to spot the pattern yourself on any device
and many more!
We include a case where our own approach has the same weakness, because a list like this is worthless if it only points outward.
Key Points:
Shark's CryoGlow cooling is cleared to refresh, invigorate and soothe the skin, and the product page says it helps visibly tighten under-eyes.
NIRA's clearance covers periorbital wrinkles, and the larger model is marketed for neck, chest and hands, which the company acknowledges it plans to seek clearance for.
7E Wellness sells the MyoLift Mini on muscle toning while its own FAQ states that true microcurrent cannot cause a contraction of the muscle.
HigherDOSE publishes an irradiance split of 26 and 24 mW/cm2 on its page and 20 and 30 in its filing, with the same total of 50.
Bio-Therapeutic describes its device as FDA approved, and no facial device in this class is approved, because approval is a different pathway.
Why the filing is the better document
A product page is written to sell and a filing is written under a legal obligation to describe the device accurately to a regulator.
When the two disagree, the filing is the one with consequences attached.
None of the five cases below is fraud, and several are ordinary drafting errors of the kind any company makes.
What they have in common is that a buyer reading only the page would expect something the paperwork does not support.
Cooling that soothes, sold as tightening
Shark's CryoGlow filing describes the under-eye cooling as intended to refresh, invigorate and soothe the skin, and places it outside the cleared treatment indication, which covers the LEDs for wrinkles and acne.
The product page says the cooling helps visibly tighten under-eyes in one use, and offers temperature-controlled soothing and tightening.
Cold constricts vessels and reduces the look of puffiness for a while, which is real and pleasant, and it is not tightening.
No temperature is published anywhere, on the page or in the filing, for the function the product is named after.
Cleared for the eye area, sold for the chest
NIRA's clearance covers the treatment of periorbital wrinkles, which is what the device was designed for and does well.
The larger model is marketed for full face, neck, chest and hands, and the company notes it plans to pursue further clearance for those areas.
That is a candid acknowledgement, and it sits on the same page as the marketing rather than in place of it.
The practical consequence is that the evidence behind the clearance concerns a small area around the eye, not the chest.
A brand contradicting itself
7E Wellness sells the MyoLift Mini on language about toning and lifting facial muscles, firming sagging skin and lifting the jawline.
Its own FAQ, answering a customer who feels nothing, states that true microcurrent is sub-sensory and cannot cause a physical or visual manipulation of the muscle.
Both statements are 7E's and they describe different mechanisms.
The honest reading is that microcurrent works at skin level through cellular effects, which is real, and that muscle-toning vocabulary borrowed from the gym does not describe it.
Skin Gym does the same thing at a lower price, saying its wand helps stimulate facial muscles at up to 500 microamps, with no study and no clearance behind the claim.
A split that does not match
HigherDOSE publishes a total irradiance of 50 mW/cm2 on its own page, given as 26 red and 24 near infrared.
Its FDA filing gives the same total as 20 red and 30 infrared.
Nothing about the overall dose changes, and we mention it because a buyer choosing on the red figure specifically would be working from a number the filing does not support.
This is the mildest case here and the most likely to be a simple transposition.
The wrong word entirely
Bio-Therapeutic's product page describes the bt-sculpt GEN2 as FDA approved, and its footer carries a badge reading FDA Registered Medical Device Manufacturer.
Approval is a pathway reserved for higher-risk devices and no at-home facial device goes through it, ours included.
Registration is a factory address on a list rather than any review of a device.
The clearances themselves exist, filed by the parent company, so this is a wording problem rather than a missing-paperwork problem, and the wording still tells a buyer something untrue.
Where our own approach is weakest
We publish output at a stated load, pulse width, clearance numbers and country of manufacture, and we think that is the right standard.
What we do not publish is a measured figure for how much more of an ingredient our Infuse pass delivers into skin, because we have not run that measurement on our own device.
We cite the underlying delivery science, Prausnitz 1993 on electroporation and Zhang 1999 on iontophoresis, and neither of those studies was run on a PureLift.
That is the same shape of gap we have just described in five other companies, and it is fair for a reader to hold it against us until we close it.
How to check any device yourself
Find the filing, read the indications for use, and compare that paragraph with the claims on the page.
Look for functions sold as treatments that the clearance describes as comfort features.
Look for treatment areas in the marketing that do not appear in the indication.
Check whether any figure on the page appears differently in the filing, and treat the filing as correct.
Our guide to running the 510(k) search takes about two minutes and works on any brand in this market.
