XERF RF Skin Tightening in San Diego, CA
XERF at Seoule K-Beauty Skin Lab in San Diego is a revolutionary Korean aesthetic technology that lifts, tightens, sculpts and smooths the face and body without surgery, needles or downtime. As the world's first multifrequency monopolar RF system, FDA-cleared in 2025, it delivers visible lifting in as little as 1-2 sessions. Seoule is an official XERF Ambassador Clinic.
What is XERF treatment?
XERF is the world's first multifrequency monopolar radiofrequency system, FDA-cleared for non-invasive skin tightening and lifting. It delivers two frequencies, 6.78 MHz and 2 MHz, at the same time, sending precise, controlled heat across the superficial, mid and deep layers of the skin in a single session. This multi-depth heating remodels collagen and elastin, the proteins responsible for firm, lifted, youthful-looking skin. Developed over roughly six years of research in South Korea, it is the newest generation of K-beauty skin tightening.
What is XERF used for?
Because XERF works at multiple depths, it is remarkably versatile. At our San Diego clinic we use it for:
Jawline sculpting and double-chin reduction.
Cheek and neck lifting.
Abdomen and body tightening.
Wrinkle smoothing and overall skin firming.

Who is a good candidate?
XERF is suitable for all skin types and tones and is ideal for anyone who wants firmer, lifted skin without surgery or downtime. It is a strong choice for early to moderate skin laxity, a softening jawline, or loss of definition in the cheeks and neck. Because it is comfortable and non-invasive, it appeals to clients who cannot commit to a lengthy recovery.
What to expect and how many sessions will I need?
XERF is a comfortable, non-invasive experience with no needles and no downtime. Face and neck typically need 1-2 sessions, jawline and double chin 1-2 sessions, and abdomen or body areas 2-4 sessions depending on your goals. You will notice immediate lift and firmness after your first visit, with results continuing to improve over 4-12 weeks as new collagen forms.
How long do results last and how much does XERF cost?
Results often last about 9-12 months, and we recommend one maintenance session every 9-12 months to preserve them. 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, and the most accurate way to learn your cost is a personalized consultation at our San Diego med spa.
What is the aftercare?
XERF requires little to no downtime. Resume daily activities and stay hydrated to support collagen production. For the first 24 hours, avoid hot showers, saunas, steam rooms and intense workouts, and skip active ingredients like retinol and exfoliating acids. Over the next 3-7 days, drink 6-8 glasses of water daily, use SPF 30+, avoid aggressive massage over treated areas and eat light to support fat drainage.
Why is XERF different at Seoule?
Not all energy-based lifting devices are equal. As an official XERF Ambassador Clinic, our team received direct training from the manufacturer and leading experts in South Korea. XERF's proprietary, highly controlled heat delivery focuses on tightening, collagen remodeling and lifting while helping preserve natural facial contours. The device matters, and the expertise behind it matters even more, which is why our results-driven, physician-supervised approach sets Seoule apart.
How to prepare for your treatment
XERF needs little preparation, but arrive with clean skin, free of makeup, lotions and sunscreen on the treatment area. Avoid retinoids and exfoliating acids for a few days beforehand, stay hydrated, and remove metal jewelry from the area being treated. Let us know about any implanted devices or medical conditions so we can confirm the treatment is right for you.
Combining treatments for the best results
XERF focuses on lifting and tightening, so it complements treatments that address tone and texture. Many San Diego clients combine XERF with Sylfirm X for deeper collagen remodeling, Glow Laser for brightness, and a K-Beauty Facial for hydration, creating a complete lift-and-glow plan. It is also a natural finishing step after medical weight loss, when skin firmness matters most.
Results you can expect
Clients typically notice immediate lift and firmness after the first session, with more dramatic tightening and contour developing over the following weeks as fresh collagen forms. Because XERF works across multiple skin depths, results look natural and balanced, sculpting the jawline, cheeks and neck without surgery. With maintenance, the lifted, firmer look can be enjoyed year after year.
