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 has no established mechanism against acne, blue light at around 465 nanometres does, and neither replaces the treatments that actually clear acne.
This article sets out what to check before you start, such as:
- why blue light and microcurrent are different answers
- what the antibacterial mechanism actually is
- why an active breakout is a reason to pause
- the hygiene step most people skip
- what genuinely clears acne
and many more!
If your acne is persistent, scarring or affecting your life, the answer is a dermatologist, not a device.
Key Points:
Blue light around 415 to 465 nanometres is absorbed by porphyrins produced by Cutibacterium acnes, generating reactive oxygen that damages the bacterium; our GLOW carries blue at 465 nm.
Microcurrent and EMS work on muscle and skin appearance, and no mechanism connects either to acne bacteria or to sebum production.
Do not run a probe across inflamed, pustular or broken skin, because you will spread bacteria and worsen irritation.
Clean the probe before and after every session, which matters far more for acne-prone skin than for anyone else.
Topical retinoids, benzoyl peroxide, azelaic acid and prescription treatment are what clear acne, and a device is at best an addition.
Two different questions in one
People asking whether microcurrent helps acne are usually looking at a device that carries several technologies, and the honest answer depends on which one you mean.
Microcurrent and EMS act on muscle and on skin appearance, and the acne literature does not involve them.
Blue light is a separate technology with a separate and reasonably well described mechanism, and it is the part of a multi-technology device with a claim here.
Our GLOW carries blue at 465 nm alongside red at 634 nm and the seven other technologies on the dial, and the blue channel is the relevant one for acne.
How blue light works on acne
Cutibacterium acnes, the bacterium involved in acne, produces porphyrins as part of its own metabolism.
Porphyrins absorb light strongly in the blue range, and that absorption generates reactive oxygen species inside the bacterium, damaging it.
That is a specific, chemical mechanism rather than a general claim about light being good for skin, which is why blue light has an acne literature and other wavelengths do not.
Avendano-Coy and colleagues in 2022 reviewed electrical and light interventions in tissue contexts and the pattern across that literature is that dose and wavelength are what determine whether anything happens, which is why we publish GLOW's figures of 1.13 W/m² and 678 J/m² over ten minutes rather than just naming the colour.
Why an active breakout means pause
Running a probe across inflamed papules and pustules spreads bacteria from one follicle to the next, and the mechanical pressure makes the inflammation worse.
Broken skin and open lesions should not have a conductive gel and a current applied over them, for the same reason you would not massage a graze.
Work around active lesions, or skip the affected area entirely until it settles.
Light-only use, with no contact and no probe pressure, is the one exception, because nothing is being dragged across the skin.
The hygiene step nobody mentions
A probe that touched an inflamed area and then touched clear skin has moved bacteria there, and nothing about the current undoes that.
Clean the probe with isopropyl alcohol before and after every session, and let it dry fully before use.
Use a fresh conductive layer each time rather than topping up from a jar you have had your fingers in.
Any brand telling you about biofilms and currents while omitting the alcohol wipe has the priorities backwards.
What actually clears acne
Topical retinoids address the follicular plugging that starts the process, and they have decades of evidence behind them.
Benzoyl peroxide reduces the bacterial load directly, and azelaic acid handles both inflammation and the post-inflammatory marks.
Oral treatment, including antibiotics, hormonal options and isotretinoin, is prescribed for moderate and severe acne and is managed by a doctor.
A device sits alongside those at best, and we would rather you spent two hundred pounds on a dermatologist appointment than nine hundred on a device if acne is your main concern.
Where a device does fit
Post-acne appearance, meaning the marks and the texture left behind rather than the active lesions, is a different question with a better answer.
Red light at 634 nm addresses that territory, and the LED evidence for skin appearance sits in that wavelength range.
If your acne is controlled and you are dealing with what it left, a multi-technology device is a reasonable purchase.
If your acne is active and spreading, use the light channel only, keep the probe off the lesions, and come back to the rest once it has settled. The full technology map is in our category overview.
