What Is XERF Skin Tightening?
XERF (eXtended Energy RF) is a non-invasive monopolar radiofrequency treatment designed for structural skin tightening of the face, neck, and body. It represents a meaningful evolution in RF technology: not through a new mechanism, but through a more sophisticated delivery system that allows the device to treat multiple tissue depths in a single session.
Where earlier monopolar RF devices like Thermage operate at a single frequency, XERF runs at two frequencies simultaneously: 6.78 MHz and 2 MHz. The higher frequency addresses the superficial and mid-dermal layers; the lower frequency penetrates deeper into the SMAS, the structural layer beneath the skin that plays a central role in how the face ages. The combined effect is a single treatment that stimulates collagen remodeling across the full thickness of the skin, without surgery, without needles, and without downtime.
XERF is FDA-cleared for all skin types and tones. It is currently available at a select number of specialist clinics in New York City.
How It Works
The device delivers controlled radiofrequency energy into the skin through a handheld applicator placed on the surface. As the RF energy passes through tissue, it generates heat. That heat, when delivered at the right depth and temperature, triggers a biological response: the contraction of existing collagen fibers and the stimulation of new collagen and elastin production over the weeks and months following treatment.
XERF does this across two depths at once:
- 6.78 MHz: superficial to mid-dermis. Addresses skin texture, fine lines, and surface collagen remodeling. This is where most single-frequency RF devices operate.
- 2 MHz: deeper, into the SMAS. The same structural layer targeted in surgical facelifts. Heating this layer supports lift, definition, and long-term structural improvement in the jawline, cheeks, and neck.
The device incorporates an integrated cooling system that maintains surface skin temperature and patient comfort throughout the session. Most patients describe the sensation as a consistent, tolerable warmth, not pain. No anesthetic is required.
What It Treats
XERF is best suited for patients with mild to moderate skin laxity who want non-surgical improvement in skin firmness, texture, and contour. Common treatment indications include:
- Skin laxity on the face, neck, and jawline
- Early jowling and loss of jawline definition
- Loss of mid-face volume and cheek definition
- Loose or crepey skin on the neck and décolletage
- Fine lines and early signs of skin aging
- Skin texture irregularities
It is not a replacement for surgical procedures in cases of significant laxity. The best candidate is someone in the early-to-moderate stages of skin aging who wants to slow and address changes before they progress, or maintain results after a prior surgical or aesthetic intervention.
How XERF Compares to Other Technologies
The NYC market offers several non-invasive skin tightening technologies, each with a different mechanism, depth, and clinical profile. Understanding the differences helps you have a more informed conversation with your provider.
| XERF | Dual-frequency monopolar RF (6.78 MHz + 2 MHz). Multi-depth: dermis + SMAS. No downtime. All skin types. |
| Thermage | Single-frequency monopolar RF. Surface-to-mid dermal heating. No downtime. Longer track record. |
| Ultherapy | Focused ultrasound. Targets SMAS and superficial muscle. Variable discomfort. Some downtime possible. |
| Sofwave | Parallel beam ultrasound. Mid-dermal collagen stimulation. Minimal downtime. Lower depth than XERF. |
| Morpheus8 | RF microneedling. Strong for texture and moderate laxity. 2–5 days downtime. Needles required. |
No single technology is superior for every patient. The right choice depends on your skin anatomy, degree of laxity, skin type, downtime tolerance, and goals. Providers like SKINNEY Medspa who offer multiple technologies, including XERF, Sofwave, Thermage, Ultherapy, and Morpheus8, are well-positioned to recommend the most appropriate option during a consultation.
Who Is a Good Candidate?
XERF is FDA-cleared for all skin types and tones. The ideal candidate:
- Has mild to moderate skin laxity, not severe sagging or significant volume loss
- Wants non-surgical improvement without surgery or significant downtime
- Is willing to wait for gradual results over 3–6 months post-treatment
- Understands that one to three sessions may be required depending on their degree of laxity
- Has realistic expectations about the magnitude of improvement versus surgical alternatives
XERF is not a replacement for surgery. It is the best available non-invasive option for patients who aren't ready for surgery, or who want to maintain results after a prior procedure.
Results and Timeline
Unlike injectables, which work immediately, XERF results develop over time as the collagen remodeling process progresses. Most patients notice initial changes within 4–6 weeks. Significant improvement typically develops over 3–6 months as new collagen and elastin are produced and organized into the skin's structural framework.
Results from a single session can last 12–24 months depending on the individual. Most providers recommend periodic maintenance sessions, annually or as needed, to sustain outcomes as the natural aging process continues.

Finding a XERF Provider in NYC
XERF is currently available at a small number of specialist clinics in Manhattan. Providers range from medical spas where treatment is administered by trained RNs, to board-certified dermatology practices where XERF is performed exclusively by physicians. The right provider depends on your skin concerns, desired level of clinical oversight, and consultation preferences.
