The Nefertiti Lift and XERF are two non-surgical treatments that address different causes of lower face aging. The Nefertiti Lift uses targeted neuromodulator injections, a type of botulinum toxin sometimes referred to as Botox, to soften the platysma muscle’s downward pull on the jawline and neck. XERF uses monopolar radiofrequency energy to tighten skin and support collagen renewal. At Dr. Marie Hayag’s NYC practice, combining the two can create a more defined jawline and a firmer neck without surgery.
Why Lower Face Aging Needs More Than One Solution
A youthful jawline and neck depend on more than skin alone. Visible aging results from a combination of changes in skin quality, collagen content, soft-tissue support, muscle activity, and bone structure. Because of that, lower face rejuvenation is rarely about fixing just one thing. The most effective non-surgical strategies usually address several contributors at once.
For many NYC patients, the first concerns show up along the jawline and neck. Early jowling, a softened mandibular border, platysmal banding, and mild skin laxity can all chip away at lower face definition. In a fast-paced city, most patients want improvement that looks natural, keeps their expression intact, and doesn’t require real downtime.
A combination of the Nefertiti Lift and XERF radiofrequency skin tightening can be a smart option for the right patients. The two treatments work through different mechanisms. The Nefertiti Lift reduces the downward pull of the platysma and surrounding lower-face muscles, while XERF heats tissue in a controlled manner to improve skin firmness over time. Together, they take a layered approach to jawline and neck rejuvenation, addressing muscle-driven tension and skin laxity simultaneously.
What Is the Nefertiti Lift?
The Nefertiti Lift is an injection technique that places small amounts of neuromodulator along the jawline and into portions of the platysma, the broad, thin muscle that runs from the lower face into the neck. In some patients, a stronger platysmal pull blurs the jawline, drags the lower face downward, and creates visible vertical neck bands.
By selectively relaxing that downward pull, the Nefertiti Lift can improve the transition between the jaw and neck and create a more refined lower facial contour. It’s considered a subtle contouring and balancing treatment, not a replacement for surgical lifting. In 2024, botulinum toxin received FDA approval specifically for moderate-to-severe platysma bands, making it the first neuromodulator approved for this part of the neck and helping push the Nefertiti technique from an insider trick to a mainstream request at practices across NYC.
This distinction matters. Patients with significant skin laxity, heavy jowling, or deeper structural descent usually need a different treatment plan and may be better served by other non-surgical combinations or a surgical consultation, depending on their goals.
How Neuromodulators Improve Jawline and Neck Balance
Neuromodulators work by temporarily reducing activity in targeted muscles. In the lower face and neck, precise placement can soften downward muscular pull while preserving natural movement and expression. The goal isn’t a stiff or frozen look. It’s reducing specific downward forces just enough to improve balance.
When placed correctly, treatment can soften platysmal bands and sharpen jawline definition while preserving normal expression and function. Results aren’t immediate. Most patients notice change within several days, with the fuller effect typically developing over 10 to 14 days. Outcomes depend on anatomy, muscle strength, skin quality, and injection technique, which is why this treatment should be performed by an experienced medical injector with a strong grasp of facial musculature.
What the Nefertiti Lift Can and Cannot Do
The Nefertiti Lift can help patients with the following:
- Early loss of jawline definition: a jawline that’s starting to soften but hasn’t sagged significantly
- Mild platysmal banding: vertical neck bands that show during expression or speech
- Downward tension along the lower face: muscle pull that blurs the jaw-to-neck transition
- Subtle softening at the jaw-neck junction: early signs of a less defined lower face
It’s important to set realistic expectations. Neuromodulators don’t remove excess skin, restore lost volume, or reproduce the effect of a surgical neck lift or lower facelift. In patients with visible skin laxity, muscle treatment alone may not deliver the degree of definition they want. That’s where skin-tightening technologies like XERF can complement the results.
The Role of XERF in Jawline and Neck Rejuvenation
XERF is a monopolar radiofrequency treatment designed to deliver controlled thermal energy to the skin and underlying soft tissues. That controlled heating is meant to encourage tissue remodeling and kick-start the body’s natural collagen renewal process.
Collagen and elastin decline naturally with age, leading to thinner skin, reduced elasticity, and more visible laxity. Radiofrequency treatments like XERF are used in aesthetic medicine to improve firmness and texture in patients with mild to moderate laxity, especially those who want a non-surgical option. Unlike a neuromodulator, which targets muscle activity, XERF directly addresses skin quality and tissue support.
Improvement builds gradually rather than appearing overnight. Some patients notice an early tightening effect from tissue contraction, but the real goal is progressive firming over the following weeks to months as collagen remodeling takes hold. As with any energy-based device, results depend on patient selection, treatment settings, tissue characteristics, and baseline laxity.
Why These Treatments Work Well Together
The Nefertiti Lift and XERF complement each other because they target different aspects of lower-face aging. The Nefertiti Lift reduces muscular downward pull. XERF addresses skin laxity and supports tissue tightening over time.
Good lower-face rejuvenation takes more than just choosing a device or an injectable. At Dr. Hayag’s practice, treatment planning begins with an evaluation of facial movement, skin quality, tissue laxity, and overall facial balance. Every patient ages differently, and the most natural-looking results come from understanding the anatomy behind those changes, not from applying the same protocol to every patient who walks in.
Definition Now: Structural Support Over Time
One practical advantage of combination treatment is that improvement shows up on different timelines. The neuromodulator portion typically produces earlier visible refinement as the treated muscles relax over the first one to two weeks. Radiofrequency tightening develops more gradually, with changes in firmness and skin quality emerging over time rather than all at once.
For the right patient, that creates a useful sequence: earlier contour refinement followed by progressive textural and structural improvement. This should still be framed responsibly. Non-surgical rejuvenation can produce meaningful change, but it doesn’t replicate surgery. Patients tend to be happiest when the goal is refreshed definition and subtle enhancement rather than a dramatic lift.
Who Is a Good Candidate?
This combination may suit patients with:
- Mild to moderate jawline softening: early loss of a crisp jaw-to-neck transition
- Early neck laxity: skin that’s begun to lose firmness but hasn’t sagged heavily
- Visible platysmal bands: vertical neck cords that show during movement or expression
- Mild loss of lower face definition: a jawline that reads as softer than it used to
- Interest in non-surgical treatment: patients who want limited downtime and no incisions
It may be less appropriate for patients with significant skin redundancy, advanced jowling, marked volume loss, or a heavier lower-face descent that requires structural repositioning. A careful consultation is essential. Good treatment planning starts with evaluating the full face and neck, not just the area the patient noticed first. Skin quality, muscle activity, fat distribution, facial proportions, and skeletal support all factor into which plan makes sense.
What Treatment Typically Involves
Treatment begins with a detailed medical and aesthetic assessment that covers the patient’s goals, prior procedures, anatomy, muscle movement, and the degree of skin laxity.
For the Nefertiti Lift, small amounts of neuromodulator are placed at carefully selected points along the platysma and jawline. The procedure is brief and generally well tolerated. For XERF, the skin is prepared, and the device is applied to the target area using controlled radiofrequency energy, with settings adjusted based on anatomy, tolerance, and clinical goals. Because both are office-based procedures, most patients resume their normal routine quickly, though specific aftercare varies by treatment and provider protocol.
Recovery and Aftercare
Downtime is usually minimal for both treatments. After neuromodulator injections, patients may notice temporary redness, pinpoint swelling, tenderness, or small injection-site bumps that resolve quickly. After radiofrequency treatment, mild warmth, redness, or transient sensitivity can occur, along with a temporary feeling of tightness in the treated area.
Patients should follow post-procedure guidance on exercise, heat exposure, skincare products, and sun protection. Daily sunscreen and a consistent medical-grade skincare routine, when appropriate, help support skin quality over the long run.
How Long Results Last
Neuromodulator results are temporary. In the lower face and neck, effects commonly last several months, though duration varies with metabolism, dosing, muscle strength, and individual response. Radiofrequency results also vary by patient and device protocol, with improvement developing gradually and maintenance sometimes recommended depending on the degree of laxity, age-related change, and long-term goals.
For many patients, the best long-term outcome comes from an ongoing strategy rather than a single visit, combining neuromodulators, energy-based devices, skincare, and periodic reassessment as facial anatomy continues to change.
A Refined, Evidence-Based Approach to Jawline and Neck Rejuvenation
The Nefertiti Lift and XERF address two distinct contributors to lower-face aging: muscle-related downward pull and skin laxity. For the right patient, combining them can create a more defined jawline and a firmer, more refreshed neck without surgery.
The most natural results usually come from careful assessment, conservative technique, and realistic expectations rather than a one-size-fits-all solution. Patients interested in refining their jawline or improving neck firmness without surgery can schedule a personalized consultation with Dr. Marie Hayag to determine whether the Nefertiti Lift, XERF, or a combination approach best fits their goals.
Frequently Asked Questions About Nefertiti Lift and XERF
Will the Nefertiti Lift make my neck and jawline look frozen?
No. The Nefertiti Lift is designed to soften the platysma’s downward pull while preserving natural expression and movement. The goal is subtle definition, not a frozen or overdone appearance.
Can the Nefertiti Lift replace a surgical neck lift?
No. A surgical neck lift remains the more effective option for significant skin excess or deeper structural aging. The Nefertiti Lift works best as a subtle contouring treatment for carefully selected patients.
How quickly will I see results from Nefertiti Lift and XERF?
Neuromodulator effects typically begin within several days and fully develop over about two weeks. XERF skin tightening improves more gradually, with firmness building over the following weeks to months.
Is combining Nefertiti Lift and XERF better than one treatment alone?
Not always, but it can be. Combination treatment tends to work best when both muscle activity and skin laxity are contributing to jawline and neck aging. The right approach depends on individual anatomy and goals.
Are the Nefertiti Lift and XERF safe treatments?
Yes. Neuromodulator injections and radiofrequency skin tightening are both widely used in aesthetic medicine with established safety profiles when performed by a qualified provider with appropriate patient selection and technique.
