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.

A device reaches the muscle that creates the lines and toning it can deepen them, which makes this the one region where more muscle work is clearly the wrong move.
This article sets out what to check before you start, such as:
- the three separate causes of vertical lip lines
- why toning the mouth muscle backfires
- what sun damage and smoking actually do here
- the device settings that are safe around the mouth
- what genuinely softens these lines
and many more!
This is the second region, after the forehead, where our honest advice is to use the device less rather than more.
Key Points:
The orbicularis oris is a ring of muscle around the mouth, and every purse, sip and pucker folds the skin above it in the same places.
Toning a muscle whose contraction creates the crease deepens the crease, which is the same logic that applies to forehead lines.
Sun damage is the largest single contributor, and smoking compounds it through both the repeated pursing and the vascular effect.
Volume loss around the mouth removes the support that used to keep the skin taut over the muscle.
Resurfacing, filler and retinoids address the three real causes, and none of them is muscle toning.
Three causes behind one set of lines
The muscle
The orbicularis oris encircles the mouth, and unlike most muscles it has no bony attachment at either end, inserting into skin and into the other muscles around the mouth.
Its job is to close and purse the lips, which it does thousands of times a day in speech, eating and drinking.
Each contraction folds the skin above it radially, which is why the lines run perpendicular to the lip border rather than along it.
The skin
The skin above the upper lip is thin, has few oil glands and takes a great deal of ultraviolet exposure because of the angle it presents to the sun.
Collagen and elastin loss there is typically ahead of the rest of the face, which is why these lines appear earlier than people expect.
Once the skin can no longer spring back, the fold made by the muscle stays after the muscle relaxes.
The volume
The lip itself loses volume with age and the bone beneath the upper jaw recedes, so the platform under the skin drops away.
Less support means the skin has further to fold and less tension holding it flat.
This is the cause that responds best to treatment and the one no device touches.
Why toning here backfires
The argument for facial stimulation everywhere else is that a better-toned muscle supports the tissue above it.
Around the mouth, the muscle is not supporting the skin, it is folding it. Its contraction is the mechanism that makes the line.
Kavanagh and colleagues in 2012 measured an 18.6 percent increase in cheek muscle thickness over twelve weeks, and a comparable gain in the orbicularis oris would mean a stronger purse rather than a smoother lip.
The parallel is exact with the forehead, where stimulating the frontalis deepens horizontal lines, set out in our forehead article.
So the rule for both regions is the same. Pass over gently at a low level for circulation and serum delivery, and do not work for tone.
What smoking actually does
These lines are often called smoker's lines, and smoking contributes through two separate mechanisms rather than one.
The first is mechanical. Drawing on a cigarette purses the lips repeatedly in exactly the pattern that folds the skin.
The second is vascular and biochemical. Smoking constricts small blood vessels and accelerates collagen breakdown, which thins the skin that is being folded.
People who have never smoked get the same lines from the same muscle action, which is why the name is misleading and why stopping smoking helps without being a cure.
How to work the area safely
Keep the probe above the lip line on the cheek side, lifting upward and outward toward the cheekbone rather than sitting on the lip border.
Drop the level two or three steps below your cheek setting, because the tissue is thin and the sensation is sharper here.
Keep moving rather than lingering, since static contact on thin skin is where irritation starts.
Use a generous conductive layer and refresh it before you reach this region, because a drying layer concentrates current, covered in our article on stinging.
Avoid the vermilion border itself and avoid the muscle running down from the mouth corner, which is the depressor covered in our marionette lines article.
What actually softens lip lines
Resurfacing
Fractional and fully ablative lasers, and deeper chemical peels, remove and rebuild the damaged upper layers of skin.
This area responds particularly well because the problem is largely dermal, and it is one of the few places where aggressive resurfacing is still routinely used.
Downtime is real, measured in days to weeks depending on depth, and it is a clinic procedure.
Filler and toxin
Small amounts of filler placed into the individual lines, or into the lip body to restore volume, lift the skin and reduce the fold.
Tiny doses of botulinum toxin into the orbicularis oris reduce the pursing action without disabling speech or drinking, performed by an experienced injector.
This is technically demanding work and the practitioner matters a great deal more than the product.
Topicals and prevention
A retinoid improves dermal quality over months and has the strongest evidence of anything you can buy without an appointment.
Daily sunscreen matters more on the upper lip than most people realize, because the area is routinely missed and heavily exposed.
Lee and colleagues in 2007 ran a split-face LED study reporting improvements in skin measures at red wavelengths, which is a modest skin quality effect rather than a line correction.
Where a device still fits
If lip lines are one of several concerns and jawline definition or cheek lift also matter to you, a device remains a reasonable purchase for those other regions.
Keep the mouth region as a low-level pass rather than a target, which costs you nothing and avoids making the lines worse.
If lip lines are the single thing that bothers you, a resurfacing consultation will do more in one appointment than a year of sessions.
We would rather lose that sale than take it, which is the same position we take in our hollow cheeks article.
Frequently asked questions
Can you get rid of lip lines without filler
Resurfacing with laser or a deeper chemical peel addresses the dermal damage directly and often works better than filler for fine vertical lines. Retinoids and sunscreen help over months.
Does microcurrent make lip lines worse
Toning the muscle that purses the lips can deepen the fold it creates. Pass over the area at a low level for circulation rather than working it for tone.
Why do I have lip lines if I never smoked
The muscle around the mouth folds the skin every time you speak, drink or purse your lips, and sun exposure thins that skin. Smoking accelerates both but is not required.
What is the best treatment for vertical lip lines
Fractional or ablative laser resurfacing has the strongest track record, often combined with small amounts of filler. A dermatologist or plastic surgeon assesses which applies.
Does sunscreen help lip lines
Yes, and the upper lip is one of the most commonly missed areas. The angle of the skin means it takes heavy ultraviolet exposure, which is the largest contributor to the dermal damage behind the lines.
