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.

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 pens can deliver a small current to one spot at a time, rollers often rely on massage with a small solar or body-generated current that brands rarely measure, and patches vary widely, so check for a stated current, a conductive gel and an FDA clearance before you trust any of them.
This guide explains each format, such as:
- how microcurrent pens work
- what solar-powered rollers claim
- what microcurrent patches are
- how to tell real microcurrent from marketing
- when a full handheld device makes more sense
and many more!
We make handheld microcurrent devices, so we explain where the cheaper formats help and where they fall short.
Key Points:
Pens have a small tip and are used on lines and small areas, one spot at a time.
Some rollers, such as ReFa Carat, use a solar panel and say they generate a weak microcurrent; the main effect most people feel is massage.
Patch products vary widely, and few publish a measured current.
A real microcurrent device states its output, asks for a conductive gel and ideally has an FDA clearance.
For a lifted look across the whole face, a handheld device with two contact points covers far more muscle per session.
Why these formats exist
Handheld microcurrent devices usually cost from a couple of hundred dollars upward. Pens, rollers and patches offer a cheaper or more convenient way in, and they are often sold with the same words, lift, tone and sculpt, as full devices.
The words are the same, but the technology underneath is not. Before buying, it helps to understand what each format can physically deliver to your face.
Microcurrent pens
A pen has a small metal tip and usually a second contact you hold in your hand, so the current passes from the tip through your face and back through your body. It works on one small point at a time, which is why pens are sold for lines around the eyes, mouth and forehead.
Because the tip is so small, a pen covers very little muscle per pass compared with a handheld device with two wide contact points. Our review of one popular pen is in our GESKE microcurrent review.
Microcurrent rollers
Rollers glide over the face like a massage tool. Some, such as the ReFa Carat range from MTG in Japan, have a solar panel and say the panel generates a weak microcurrent. Brands rarely publish how much current reaches the skin, and these rollers are not used with a conductive gel.
What most people notice from a roller is the massage itself, which can leave the face feeling refreshed and less puffy for a while. Massage tools are compared in our microcurrent vs gua sha article.
Microcurrent patches
Patch products range from simple adhesive pads with a small battery to sheet masks that say they carry a charge. Few publish a measured current, a frequency or a clinical study, which makes them hard to judge.
If a patch has no stated output and no clearance, treat any lifting claim with caution. Masks are covered in our article on microcurrent masks.
Side by side
| Pen | Roller | Patch | Handheld device | |
|---|---|---|---|---|
| Area per pass | One small point | Wide, massage | Fixed spot | Wide, two contacts |
| Stated current | Sometimes | Rarely | Rarely | Usually |
| Needs gel | Usually | No | No | Yes |
| Best for | Small lines | Massage, depuffing | Convenience | A lifted look across the face |
How to tell real microcurrent from marketing
Look for a current figure in microamps or milliamps, not just the word microcurrent.
Check whether the brand asks for a conductive gel or serum, because microcurrent needs one to flow evenly.
Look up the FDA clearance for the exact product, using our FDA clearance guide.
Our list of every published output figure for facial devices explains what to compare.
When a full device makes more sense
If you want a firmer jaw, lifted cheeks and brows, you need enough current across enough muscle, several times a week. A randomized controlled trial by Kavanagh and colleagues, published in 2012, measured the effect of facial electrical stimulation after twelve weeks of regular use.
Pens and rollers can sit alongside a full device for small areas or massage. Our guide to choosing one is in our microcurrent device buying guide.
Our devices run nanocurrent at level 1, microcurrent at level 2 and EMS from level 3 to 10, plus an Infuse pass, on one dial, with a ten minute session and no more than three minutes per side of the face, and they work with any water-based conductive serum.
Do not use any facial current device if you have a pacemaker or other implanted electronic device, if you are pregnant or if you have epilepsy, and skip broken or irritated skin. The full list is in our safety article.
Frequently asked questions
Do microcurrent pens work
They can deliver a small current to one spot at a time, which suits fine lines more than overall lifting.
Do microcurrent rollers really have microcurrent
Some solar rollers say they generate a weak microcurrent, but brands rarely publish how much reaches the skin.
Do microcurrent patches work
Few patch products publish a measured current or study, so results are hard to judge.
Is a microcurrent pen as good as a NuFACE
A pen covers a much smaller area per pass than a two-contact handheld device.
How can I tell if a device has real microcurrent
Look for a stated current, a conductive gel requirement and an FDA clearance for that exact product.
