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 headache after a session is usually caused by the level being too high over the temples, by jaw clenching during the session, or by dehydration, and all three are fixable.
This article sets out what to check before you start, such as:
- why the temples are the most common trigger
- the clenching most people do not notice they are doing
- why hydration matters more than it sounds
- how to adjust without giving up the session
- the headache symptoms that are an emergency
and many more!
Most session headaches resolve with a lower level and a change of technique, and the ones that do not belong with a doctor.
Key Points:
The temporalis muscle covers the temple, and stimulating it at a level chosen for the cheek is the single most common cause of a post-session headache.
Many people clench their jaw while concentrating on a device, and a clenched jaw for ten minutes produces exactly the headache people blame the current for.
Dehydration lowers skin conductivity, so people compensate by raising the level, which makes the problem worse rather than better.
Lower the level over the temples and forehead specifically rather than for the whole session.
A sudden severe headache, a headache with visual changes, weakness or confusion, or the worst headache of your life is a medical emergency and has nothing to do with the device.
The temples are usually the answer
The temporalis is a broad fan-shaped muscle covering the side of the head above the ear, and it is one of the muscles that closes the jaw.
A stimulation level that feels comfortable on the cheek is frequently too strong over the temporalis, because the muscle is large, superficial and connected to jaw function.
Stimulating it repeatedly at that level produces a tension headache in the same way a long day of clenching does.
The fix is to drop the level by two or three steps when you move above the cheekbone and to keep the passes over the temple short.
The clenching nobody notices
Watch someone use a facial device for the first time and you will usually see a set jaw, because concentrating on a new tool and on the mirror produces exactly that.
Ten minutes of held clenching is enough to produce a headache in most people, entirely independent of what the device is doing.
The remedy is simple and slightly ridiculous: rest your tongue behind your top teeth, let your back teeth come apart, and check your jaw once or twice during the session.
If you clench habitually rather than only during sessions, that is worth reading about in our article on jaw clenching.
Hydration and the level creep
Conductive gel or serum carries the current, and dry skin or a drying layer raises resistance, so the sensation fades mid-session.
The instinctive response is to turn the level up, which means that when the layer is refreshed or a better-contacting area is reached, the delivered current jumps.
Reapply the conductive layer instead of raising the level, and keep the level where it was comfortable.
Being properly hydrated through the day helps for the same reason, which is why the advice appears on almost every brand's page and is usually left unexplained.
What to change, in order
First, drop the level. If the headache stops, you have your answer and can work back up slowly.
Second, shorten the session. Ours run ten minutes, three minutes per side at most, and there is nothing wrong with starting at five while you find your tolerance.
Third, refresh the conductive layer more often and stop raising the level to compensate for a dry patch.
Fourth, skip the temples entirely for a fortnight and see whether the headaches stop, which tells you where the trigger is.
Migraine is a separate question
If you have migraine, sensory input of many kinds can be a trigger, and a facial stimulation session is a plausible one for some people.
That is not the same as the device causing harm, and it is an individual pattern rather than a general finding.
Keep a simple note of sessions and headaches for a few weeks, because the pattern usually becomes obvious quickly.
If a device reliably triggers your migraine, stop using it. No cosmetic result is worth that trade, and we would rather say so than sell you a workaround.
When it is not about the device
Seek emergency care for a headache that comes on suddenly and severely, a headache with visual loss, weakness, slurred speech or confusion, a headache with fever and a stiff neck, or a headache after a head injury.
See a doctor for headaches that are new for you, that are getting more frequent, or that wake you from sleep.
None of those belongs in a conversation about a cosmetic device, and a brand telling you to adjust your technique in response to them would be doing you harm.
Stop, and get assessed.
