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.

If your double chin is fat under the chin, a microcurrent or EMS device will not remove it, and the muscle work underneath can still improve how the area reads.
This article covers what actually decides the answer, such as:
- what sits under the chin, in order of contribution
- why no device at any price removes fat
- what the platysma contributes and how to work it
- the difference between a fat chin and a slack one
- what actually addresses submental fat
and many more!
This is the shortest honest answer in the set and we would rather give it than sell around it.
Key Points:
Most of a double chin is submental fat, which no electrical device removes.
The platysma runs under the chin and across the neck, and its tone affects how defined the area looks.
Weight change moves this area more than any device will.
Posture and screen position contribute more than people expect.
Submental fat is addressed by injectable deoxycholic acid, cryolipolysis or surgery, none of which we make.
What is actually under there
The area under the chin, which clinicians call the submental region, contains a fat pad sitting above and below the platysma muscle, with skin over the top and the mylohyoid and digastric muscles deeper still.
In most people with a visible double chin, fat is the largest contributor by a wide margin, followed by skin laxity in older faces and platysma tone.
Genetics decide a good deal of it. Some people carry submental fullness at a low body weight because of where their fat sits and how far forward their chin projects, and no routine changes bone position.
A recessed chin, which is a skeletal feature, creates the appearance of submental fullness at any weight, and a surgeon assessing that would be talking about a chin implant rather than a device.
Why no device removes fat
Electrical stimulation at the currents used in facial devices contracts muscle and acts on cells; it does not lyse fat cells or move fat out of a compartment.
That is true at 300 microamps and true at 9 milliamps. The difference between a microcurrent device and ours is whether a muscle contracts, not whether fat is affected, because neither affects fat.
Any brand implying that a handheld device removes fat under the chin is describing something its own technology does not do, and it is worth being suspicious of everything else on that page.
Body-contouring devices that do target fat, such as cryolipolysis systems, work by a completely different mechanism and are a clinical rather than a bathroom proposition.
What the muscle work does contribute
The platysma runs from the jaw down across the front of the neck, and its tone affects how cleanly the jaw separates from the neck.
Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness across twelve weeks of motor-level stimulation, and while that measurement was taken at the cheek, the mechanism applies wherever a muscle is asked to work.
Better platysma tone tightens the visual line between jaw and neck, which can make a modest submental fullness read as less prominent without removing anything.
So the honest claim is definition rather than reduction, and the difference matters if you are deciding whether to spend.
Fat or slack, and how to tell
Tilt your head back and look in the mirror. If the fullness largely disappears, a good part of what you see is skin and platysma laxity, which responds to muscle work and to skin-focused treatment.
If the fullness remains with your head back, you are looking at fat, and a device will not address it.
Pinch the tissue under your chin. A thick, soft pad that you can hold is fat. Thin skin that folds but has little substance behind it is laxity.
Neither answer is a diagnosis, and a consultation with someone who does not sell devices is the sensible next step if you are considering spending significantly.
What actually addresses submental fat
Weight change is the largest lever for most people, and it is the one nobody wants to hear in an article about devices.
Injectable deoxycholic acid destroys fat cells in the area over a course of treatments, with real downtime and swelling.
Cryolipolysis applied to the submental area is a clinical treatment with its own trade-offs.
Submental liposuction, sometimes with a neck lift, is the surgical route and the most definitive.
We make none of those and have no financial reason to recommend them, which is exactly why this list is in the article.
If you are going to use a device anyway
Work the platysma with passes running under the jawbone from the chin outward toward the ear, and down onto the upper neck if your device is rated for it, avoiding the front of the throat over the thyroid.
Expect improvement in the jaw line above the area rather than in the pad itself.
Combine it with the mid-face work, since supporting the tissue higher up changes how the whole lower face reads.
And judge it at twelve weeks from a photograph taken slightly below the chin, which is the angle that flatters nobody and therefore tells the truth.
