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.

Share
Radiofrequency heats the dermis to provoke a collagen response, and EMS contracts the muscle underneath, so the Titan and PureLift Pro are not alternatives to each other.
This article compares the two on what decides the result you actually see, such as:
- what radiofrequency does to tissue, in plain terms
- why 43 degrees is the number that matters
- what Silk'n does not publish about its own device
- the clearance we could not find under this model name
- when RF is genuinely the better purchase
and many more!
If a clinician has told you your skin needs heat-driven collagen remodelling, buy an RF device rather than ours.
Key Points:
Silk'n Titan MultiPlatform is $549 and combines bipolar radiofrequency, light and infrared in fifteen-minute sessions twice a week.
Silk'n publishes no RF frequency, no wattage, no wavelength and no clearance number for this model, only that a thermal sensor pauses heating at about 43 degrees Celsius.
We found no 510(k) under the MultiPlatform name; the nearest record is K230013 for the Silk'n Titan AllWays, which gives 1 MHz and up to 10 W and describes LEDs rather than a laser.
RF works on the dermis and stops well below the temperature at which collagen contracts, so it is a slow remodelling stimulus rather than an immediate tightening.
PureLift Pro is $699, publishes 7 mA at 500 ohms, is cleared under K230506, and works on muscle rather than on the dermis.
What radiofrequency actually does
Radiofrequency current passes through tissue, the tissue resists it, and that resistance produces heat.
The target is dermal collagen, and home devices cap out around 42 to 43 degrees Celsius, well below the roughly 60 to 65 degrees at which collagen denatures and contracts.
So home RF is not tightening anything on the spot, it is applying a sub-injury heat stress that prompts fibroblasts to lay down collagen over weeks.
That is a real mechanism with real evidence behind it, and it is a different mechanism from asking a muscle to contract.
What Silk'n does not publish
The product page gives a session length, a treatment schedule and a maximum skin temperature, and nothing else.
There is no RF frequency in megahertz, no power in watts, no wavelength for the light, and no country of manufacture.
We could find no clearance under the MultiPlatform name at all, in any search we ran.
Its sibling device, the Titan AllWays, does have a clearance, K230013, which publishes 1 MHz, up to 10 W, a 4.7 square centimetre treatment surface and LEDs at 630 and 850 nm.
That last detail is worth noting, because Silk'n markets the MultiPlatform's light as low-level laser therapy while the sibling's regulatory record describes LEDs.
The consumable
The Titan needs a slider gel, which is included with this bundle and refills at $15.99 for six ounces.
That is the cheapest consumable of any device requiring one that we have examined, and worth crediting.
PureLift works with any water-based serum you already own, so there is no required conductor either way.
What PureLift Pro does
Six technologies on one ten-level dial: Infusion, iontophoresis, nanocurrent at level 1, microcurrent at level 2, EMS from level 3 and PDM underneath.
Pro publishes 7 mA at 500 ohms with a 4 microsecond pulse width, is cleared under K230506, and is made in Japan in an ISO 13485 facility.
Kavanagh and colleagues measured an 18.6 percent increase in cheek muscle thickness over twelve weeks of motor-level stimulation (10.1111/jocd.12007).
A session is ten minutes, three minutes per side maximum, against fifteen minutes twice a week on the Titan.
Which problem do you have
If your skin itself has gone crepey and lost quality, that is a dermal problem and RF addresses it more directly than muscle work does.
If the shape of your lower face has changed, with the jawline softening and the cheeks dropping, that is contour, and heating the dermis does comparatively little for it.
Many people have both, in which case the two devices are complementary rather than competing, and neither replaces the other.
We do not make an RF device and have no plans to, so this is not a category we are trying to talk you out of.
Which to buy
Buy the Titan if dermal laxity and texture are the complaint, if you want face, neck and decolletage coverage, and if you are content to buy without published engineering.
Consider an RF device that publishes more if the figures matter to you, since at least one competitor publishes frequency, wattage and its thermal cutoff in its regulatory record.
Buy PureLift Pro if the complaint is contour, and run it as the muscle half of a routine where RF, if you use it, does the skin half.
