XERF skin tightening is an FDA-cleared, non-surgical treatment that uses dual-frequency monopolar radiofrequency energy to firm loose skin on the face and neck. At Dr. Marie Hayag’s NYC dermatology practice, each XERF treatment is customized to the patient’s skin quality, facial anatomy, and long-term aesthetic goals, so results look natural rather than overdone.
A Physician-Led Approach to Modern Skin Rejuvenation
More NYC patients are choosing aesthetic treatments that improve skin quality without changing who they are. The goal isn’t a different face. It’s a refreshed, healthy, and confident one.
Facial aging involves more than one isolated concern. Collagen production slows, skin elasticity changes, and facial support structures shift over time. Treating these changes well takes more than a single technology. It takes an understanding of facial anatomy and how each patient ages differently.
At Dr. Marie Hayag’s practice, XERF skin tightening is approached from a full dermatologic perspective. As a board-certified dermatologist and a leader in regenerative aesthetic dermatology, Dr. Hayag pairs medical expertise with an artist’s eye for balance, building treatment plans around healthy, natural-looking results.
What Is XERF Skin Tightening?
XERF is an FDA-cleared, non-surgical skin-tightening system that uses two radiofrequency frequencies, 6.78 MHz and 2 MHz, delivered in a single session. Most RF devices operate at a single frequency and reach only a single depth in tissue. XERF’s dual-frequency design lets Dr. Hayag treat the mid-dermis and the SMAS layer, the same structural tissue addressed in a surgical facelift, without incisions or needles.
Collagen is the protein responsible for skin’s firmness and structure. As collagen production declines with age, patients often notice softer contours, fine lines, and a loss of definition along the jawline. XERF’s radiofrequency energy heats these deeper tissue layers in a controlled way, triggering the body’s natural collagen remodeling response over the following weeks and months.
For patients who want firmer, better-defined skin without surgery or significant downtime, XERF offers a treatment built around the skin’s own regenerative process.
Why Expertise Matters More Than the Technology
Energy-based skin-tightening devices are everywhere in aesthetic medicine now, but the safety and quality of the results depend on the provider, not just the device. Skin laxity is shaped by several factors, including:
- Skin elasticity: how well the skin springs back after movement
- Facial structure: bone and tissue support beneath the skin
- Degree of tissue laxity: how much sagging or looseness is present
- Aging patterns: how a patient’s face has changed over time
- Previous aesthetic treatments: prior injectables, devices, or procedures
At Dr. Hayag’s practice, every XERF consultation starts with understanding the patient as a whole, not just the area they’re concerned about. A softer jawline, for example, might come from skin laxity, volume loss, muscle activity, or some combination of the three. Identifying the real cause is what leads to the right treatment recommendation, and Dr. Hayag’s background in skin biology and facial harmony guides that decision at every step.
Meet Dr. Marie Hayag: Where Science Meets Artistry
Dr. Marie Hayag built her approach to dermatology around a mix of scientific training and artistic instinct. Her interest in aesthetics grew from an appreciation for proportion, structure, and the distinctiveness of each patient’s features.
As a board-certified dermatologist, Dr. Hayag applies that perspective to advanced skin treatments and regenerative approaches, including XERF. She’s also known for her work in topical exosome science, developing her FABrx EXO3 Cream and Serum to support skin health and renewal.
That interest in regenerative skincare reflects a broader philosophy that guides her practice: healthy skin is the foundation on which every lasting aesthetic result is built.
What to Expect During a XERF Treatment
A XERF treatment session typically takes place in the office and doesn’t require anesthesia or numbing cream. Dr. Hayag prepares the treatment area, then applies the device handpiece to deliver radiofrequency energy beneath the skin’s surface. Settings are adjusted throughout based on the patient’s comfort and treatment goals.
Most patients describe the sensation as a steady, controlled warmth. Because XERF doesn’t involve incisions or needles, patients typically return to their normal routine the same day. Some notice temporary redness or warmth in the treated area, which usually resolves within a few hours.
When Do XERF Results Appear?
XERF results build gradually because collagen remodeling is a biological process, not an instant change. Some patients notice early improvement soon after treatment, with continued firming over the following months as the skin responds. Individual results depend on a few factors:
- Age: skin with more collagen reserve tends to respond faster
- Genetics: some patients naturally produce collagen more efficiently than others
- Skin condition: sun damage and prior treatments affect the starting point
- Lifestyle habits: diet, hydration, and skincare routine all play a role
- Sun exposure: unprotected sun exposure can undo collagen gains over time
Keeping up with sun protection and a consistent skincare routine after treatment helps patients hold onto their results longer.
Who Is a Good Candidate for XERF?
XERF works best for patients with mild to moderate skin laxity who want visible improvement without surgery. Patients often consider XERF for:
- Loss of firmness: along the cheeks or lower face
- Early jawline changes: that haven’t progressed to significant sagging
- Mild neck laxity: or the beginning of a softened neck contour
- Reduced skin elasticity: from sun exposure or natural aging
- Preventative skin maintenance: before laxity becomes more noticeable
Patients with significant excess skin or advanced structural changes may be better candidates for a surgical consultation instead. Dr. Hayag reviews each patient’s anatomy and goals during a consultation to determine whether XERF, a surgical referral, or a combination approach makes the most sense.
Why NYC Patients Choose a Physician-Led Practice
NYC has no shortage of aesthetic treatment options, but the technology alone doesn’t determine the outcome. A physician’s understanding of skin biology, facial anatomy, and treatment selection plays the biggest role in achieving a natural-looking result.
At Dr. Hayag’s practice, XERF skin tightening is guided by dermatologic training, evidence-based treatment strategies, and an eye for facial balance, not a one-size-fits-all protocol. That combination of advanced technology and physician judgment is what NYC patients are increasingly looking for when they choose where to go for skin tightening.
Advanced Technology, Personalized Care Awaits You
XERF represents a real step forward in non-surgical skin tightening, using dual-frequency radiofrequency energy to support collagen remodeling at multiple depths. For NYC patients, the technology is only half the equation. The expertise behind it, evaluating each patient’s anatomy, setting the right treatment parameters, and building a plan around their goals, is what turns a good device into a great result.

Frequently Asked Questions About XERF Skin Tightening
Is XERF a replacement for a facelift?
No. XERF is a non-surgical treatment that improves skin firmness and collagen quality, but surgical facelifts remain the most effective option for significant skin excess or advanced tissue repositioning.
Does XERF skin tightening require any downtime?
Most patients return to their normal routine immediately after treatment. Some experience mild, temporary redness or warmth in the treated area that typically resolves within a few hours.
How long do XERF results last?
Results vary by patient and depend on factors like age, skin condition, and sun exposure. Many patients maintain their results for a year or longer with proper skincare and sun protection.
Can XERF be combined with other treatments?
Yes. XERF is often combined with injectables, medical-grade skincare, or other regenerative treatments as part of a broader aesthetic plan tailored to each patient’s goals.
What makes XERF different from other RF skin-tightening devices?
XERF uses two radiofrequency frequencies, 6.78 MHz and 2 MHz, in a single session. This dual-frequency design reaches both the mid-dermis and the SMAS layer, the same structural tissues addressed in a surgical facelift.
