One of K-beauty’s most in-demand skin treatments has arrived stateside. Cynosure Lutronic’s XERF™ system was FDA-cleared in August 2025, and it’s officially entering U.S. aesthetic practices to take on signs of aging with the power of radio frequency—all without the needles!
Energy-based treatments designed to tighten skin work by heating layers of the dermis to jumpstart collagen and elastin production. And radio frequency, often combined with microneedling, is a great option to deliver that energy, resulting in tighter, smoother skin with minimal downtime.
XERF uses multiple frequency monopolar energy (6.78 MHz and 2 MHz frequencies) to get deeper and more targeted results without needles. At the same time, cooling technology keeps the treatment comfortable without numbing. With three depth settings and ten intensity levels, the device is also fully customizable.
As the first platform to offer multifrequency monopolar RF energy, XERF has become a titan in the Korean beauty industry. And now that the treatment has landed in the U.S., aesthetic practices are gearing up to introduce this non-invasive skin-tightening option to patients.
“Securing clearance for the XERFdevice in the U.S. marks a major milestone for Cynosure Lutronic as we accelerate our growth across North America,” Lowinn Kibbey, President, North America at Cynosure Lutronic, said in a press release. “The U.S. market represents one of the largest and most dynamic aesthetics markets in the world, and we’re proud to now offer patients and providers access to a breakthrough skin-tightening solution that delivers powerful results with a more comfortable, non-invasive experience.”
