Tighten Loose Skin Without Surgery
Sagging skin, softening jawlines, and lost firmness are a natural part of aging — but you don't need surgery to address them. At SDBotox, our experienced San Diego providers offer non-surgical skin tightening powered by XERF, a breakthrough radiofrequency treatment that reaches every layer of your skin to firm, lift, and smooth — comfortably, and with zero downtime.
Whether you're treating your face, neck, or body, our team builds a personalized XERF plan around your skin and your goals.
What is XERF skin tightening?
XERF is the world's first multifrequency monopolar radiofrequency (RF) skin tightening treatment. By combining two frequencies — 6.78 MHz and 2 MHz — XERF delivers energy into the shallow, middle, and deep layers of your skin, all the way to the SMAS, the foundational tissue responsible for lift and firmness.
That controlled energy prompts your skin to remodel and strengthen its own collagen over time, producing tighter, smoother, more defined skin. Think of it as rebuilding your skin's support structure — not just treating the surface.
XERF is Korean-engineered by Lutronic, refined over years of use in South Korea — a market known for setting the pace in skincare technology — and only recently brought to the United States. It uses Wave Fit™ pulse technology and Integrated Cryogen Delivery cooling to keep the surface of your skin comfortable while the energy works below, for a truly Never-Numb™ experience.
Korean innovation, now in San Diego
Korean aesthetic technology has earned a global reputation for being gentle, precise, and ahead of the curve — and XERF is the latest example to reach American patients. After years of proven use in Korea, it's now one of the newest skin tightening options available in the U.S., and SDBotox is among the first practices in San Diego to offer it.
Being early has its perks. Because XERF is brand new to the U.S., we're offering an introductory opportunity for patients who want to be among the first to experience it. Ask about our current XERF offer when you book.
Where XERF can treat
XERF isn't just for the face. Because its energy can be tuned to different depths and intensities, it firms and tightens skin across the body wherever laxity shows up:
Face
Increase overall firmness and definition
Neck & Jawline
One of the most-requested areas, where XERF reaches the deeper tissue behind sagging and jowls
Abdomen
Tighten loose skin, including after weight change or pregnancy
Upper Arms
Smooth and firm crepey or lax skin
Buttocks & Thighs
Tighten and refine without surgery or downtime
Your provider will map the right areas and settings to your goals at your consultation.
Who is a good candidate for XEFR?
Nearly everyone. XERF is one of the few skin tightening treatments that makes sense at almost any age:
If you're noticing laxity now, XERF delivers a tightening effect you can feel right away, and results that keep improving as your collagen rebuilds over the following months.
If you're younger and thinking ahead, XERF is an ideal way to "collagen bank" — building and preserving collagen now, while you have more of it, to slow the visible signs of aging before they start.
Because it requires no needles, no numbing, and no downtime, XERF fits easily into any schedule and suits a wide range of skin types. A consultation is the best way to confirm it's right for you.
Most patients begin with two treatments about one month apart to kick-start collagen production. After that, a single maintenance session every one to two years is typically all it takes to keep your results looking their best.
Each session takes roughly 30 minutes, and you can return to your day immediately afterward.
