A brand-new K-beauty innovation has made its way to Long Island—and one Smithtown med spa is the first to offer it. XERF™, the latest radiofrequency (RF) skin-tightening technology from Cynosure Lutronic, earned FDA clearance in August 2025 and is now officially available in the U.S. Liquid Luxury Aesthetics is the first and only practice on Long Island to bring this next-gen device to patients.
For anyone curious about non-invasive tightening, here’s the big deal: energy-based treatments work by gently heating the dermis to stimulate collagen and elastin production—the structural proteins that keep skin firm and bouncy. Traditionally, RF treatments are paired with microneedling to deliver that energy deeper into the skin. XERF breaks that mold.
“As our practice continues to expand, I’m committed to bringing in technology that is truly effective, safe, and backed by real science—not just hype,” says Ina LaRocca-Tocco, NP, owner of Liquid Luxury Aesthetics. “After extensive research, training, and hands-on evaluation, XERF stood out because it offers remarkable skin-renewal results with minimal downtime and has a safer risk profile for patients with pigmentation concerns.”
Instead of needles, XERF uses dual-frequency monopolar RF (6.78 MHz and 2 MHz) to target multiple layers of the skin simultaneously. This gives providers more depth, precision, and control, and gives patients a smoother, tighter look without the pinpricks. Built-in cooling tech keeps the treatment comfortable (no numbing required), and with three depth settings plus ten intensity levels, the device can be tuned to everything from early laxity to more advanced sagging.
“XERF also gives my patients an option for rejuvenation any time of year, including those who usually have to avoid lasers because of melasma or post-inflammatory pigmentation risk,” she adds. “We’re proud to be the first and only provider on Long Island offering this treatment. Bringing unique, advanced technologies to our community is part of our mission.”
Already a major player in the Korean aesthetics world, XERF is expected to become a go-to for anyone seeking visible tightening with zero downtime.
I tried the treatment myself. It felt hot on my skin but not intolerable. I was offered ProNox to offset any discomfort, but didn’t feel I needed it, so I skipped it. The whole session took about 45 minutes. When I walked out, my skin wasn’t red or irritated at all—I even went straight to dinner later that evening. In the days that followed, I had no pain, no lingering heat, and no redness. It takes two to six months to see the effects of collagen stimulation. For best results, it’s recommended to get two treatments spaced four weeks apart.
If you're considering skin tightening but want to skip needles, numbing, and downtime, XERF at Liquid Luxury Aesthetics may be your new favorite option.
