What Is XERF Skin Tightening?

XERF is a non-invasive radiofrequency treatment that tightens skin by stimulating collagen without surgery or needles. This next-generation radiofrequency (RF) treatment delivers controlled thermal energy deep into the skin, gently heating the tissue to stimulate collagen remodeling and new collagen production. The result is skin that appears firmer, smoother, and more lifted over time.
How Does XERF Work?
The advanced RF technology used by XERF delivers consistent, targeted heat to the deeper layers of the skin while protecting the surface. This controlled heating:
- Encourages collagen contraction for immediate firmness
- Triggers long-term collagen regeneration
- Improves skin texture and elasticity gradually
Treatments are carefully customized based on your skin quality, treatment area, and goals.

Areas Commonly Treated With XERF
XERF is versatile and effective for multiple areas of concern, including:
- Face and neck: Define the jawline, lift sagging cheeks, and smooth fine lines.
- Body: Firm loose skin on the abdomen, upper arms, thighs, or knees.
- Delicate areas: Improve tone around the eyes, mouth, or décolletage.
It is especially popular for patients who want subtle tightening along the jawline or neck without surgical intervention.
Benefits of XERF Skin Tightening
Patients choose XERF for its balance of comfort, safety, and natural-looking results.
Key benefits include:
- Noninvasive treatment with no incisions
- Minimal to no downtime
- Gradual, natural-looking tightening
- Improved skin firmness and texture
- Safe for all skin types
Results develop progressively as collagen rebuilds, helping you look refreshed rather than “overdone.”
What To Expect During Your Treatment
A typical XERF session lasts 30 to 60 minutes, depending on the area treated. The procedure begins with a provider cleansing the treatment area. Once the applicator is placed on the skin, you’ll feel a gentle warming sensation as the handheld device delivers RF energy. XERF’s advanced cooling technology keeps you comfortable throughout the treatment. There is no anesthesia required, and you can return to normal activities shortly after your visit.

Meet Dr. HoffmanXERF Results and Longevity
Some patients notice a mild tightening effect shortly after treatment. However, the most noticeable improvements develop gradually over several weeks as collagen production increases.
Results may continue to improve for up to 3 to 6 months, with longevity depending on:
- Age and skin quality
- Treatment area
- Lifestyle factors
- Maintenance treatments, if recommended
You may also schedule a XERF skin tightening treatment to maintain and enhance the results of a facelift.
Is XERF Right for You?
If you’re considering a nonsurgical skin tightening treatment and aren’t sure if XERF is right for you, Dr. Hoffman will evaluate your skin during a consultation and determine what treatment best aligns with your goals. XERF is an excellent option if you have mild to moderate skin laxity, prefer minimal downtime, and don’t mind seeing gradual improvements.
