XERF: The Non-Surgical Korean Facelift, Explained
By Dr. Lydia Park, MD, Medical Director at Seoule K-Beauty Skin Lab. Last updated: July 2026.
XERF is the world's first multifrequency monopolar radiofrequency system, FDA-cleared in 2025 for non-invasive skin tightening and lifting. It delivers two frequencies at once across multiple skin depths to remodel collagen and elastin, lifting and sculpting the face and body with no surgery, needles or downtime. Seoule K-Beauty Skin Lab in San Diego is an official XERF Ambassador Clinic.
Skin tightening technology has come a long way, and XERF represents the newest generation of it, developed over roughly six years of research in South Korea before earning United States FDA clearance. If you want firmer, more lifted skin but are not ready for surgery, here is exactly how XERF works and what to expect.
What is XERF?
XERF is a non-invasive radiofrequency device that lifts, tightens, sculpts and smooths the face and body. What makes it unique is that it is the first multifrequency monopolar RF system, delivering two frequencies, 6.78 MHz and 2 MHz, at the same time. This lets it send precise, controlled heat across the superficial, mid and deep layers of the skin in a single session, remodeling the collagen and elastin responsible for firm, youthful-looking skin. In short, it treats several depths at once, which is why results can appear quickly.
How does XERF lift and tighten skin?
As we age, collagen and elastin break down, and skin loses its firmness and definition. XERF's controlled heat triggers an immediate contraction of existing collagen, which produces a visible tightening effect, and it also stimulates the body to build fresh collagen over the following weeks. Because it works across multiple depths simultaneously, it can address both surface firmness and deeper structural support, delivering a natural lift without cutting or injections.
What does XERF treat?
Jawline sculpting and double-chin reduction.
Cheek and neck lifting.
Abdomen and body tightening.
Wrinkle smoothing and overall skin firming.
Because it is versatile and works at multiple depths, XERF can be used on both the face and the body, making it popular for clients who want a comprehensive tightening plan.
Is XERF a replacement for a surgical facelift?
XERF is not surgery, and it does not remove excess skin the way a surgical facelift can in advanced cases. What it does offer is a genuine, non-surgical lift for early to moderate laxity, with no incisions, no needles and no downtime. For many people, especially those who want to look refreshed and firm without the cost, risk and recovery of surgery, it is an ideal middle path. It is also an excellent way to maintain results and delay more invasive options.
How many sessions will I need and how long do results last?
Face and neck areas typically need one to two sessions, jawline and double chin one to two sessions, and abdomen or body areas two to four sessions depending on your goals. You will notice immediate lift and firmness after your first visit, with results continuing to improve over four to twelve weeks as new collagen forms. Results often last around nine to twelve months, and a single maintenance session every nine to twelve months helps preserve them.
What is the downtime and aftercare?
There is essentially no downtime. Mild redness or warmth is normal and usually fades within one to two hours, and you can return to normal activities right away. For the first twenty-four hours, avoid hot showers, saunas, steam rooms and intense workouts, and skip active ingredients like retinol and exfoliating acids. Over the next few days, stay hydrated, use SPF 30 or higher, avoid aggressive massage over treated areas and eat light to support drainage.
How much does XERF cost?
XERF pricing depends on the treatment area, the number of sessions and whether it is combined with other therapies. Nationally, XERF plans range from about $1,300 for a single small zone to roughly $4,700 for premium full-face-and-neck packages, with most clients investing in one to three sessions. The most accurate way to learn your cost is a personalized consultation, where we build a plan around your goals and budget.
Why does the provider matter so much with XERF?
With energy-based devices, results depend as much on the provider as on the machine. Patient selection, treatment planning, energy settings, depth and technique all shape the outcome. As an official XERF Ambassador Clinic, our team received direct training from the manufacturer and leading experts in South Korea, where the technology was developed. That expertise, combined with physician supervision by Medical Director Dr. Lydia Park, MD, is what allows us to deliver natural-looking lifting while preserving your facial contours.
Who is the ideal candidate for XERF?
XERF suits a wide range of people because it is non-invasive and safe for all skin types and tones. The ideal candidate has early to moderate skin laxity and wants a firmer, more lifted look without surgery or downtime, whether that means sharpening a softening jawline, lifting the cheeks and neck, or tightening skin on the body. It is also a popular maintenance option for clients who want to preserve their results and delay more invasive procedures, and a natural finishing step after medical weight loss when skin firmness matters most. It is not a substitute for surgery in cases of significant excess skin, and it is not recommended for clients with certain implanted devices, which we check during your consultation. For most people seeking a natural, non-surgical lift in San Diego, XERF is an excellent fit, especially when performed by a trained, physician-supervised team.
