As we age, three separate layers of facial tissue start to break down. The top layer of skin loses its firmness, collagen production in the middle layer decreases, and the deep SMAS muscle layer stretches, causing the lower face to sag. Most over-the-counter creams cannot fix these changes because they only work on the surface. To tighten loose skin, you need a treatment that reaches the deeper layers where real support comes from.
At our Beverly Hills office, we address these changes directly. Our advanced treatments focus on tightening tissue at every level. In the past, patients had to choose between surgery or basic spa treatments. Now, energy-based skin rejuvenation offers a middle ground. We use non-surgical methods to treat the surface, boost collagen, and tighten deep muscles—all in one visit.
XERF is a non-invasive treatment that uses different radiofrequency energies to reach the top skin layer, the middle dermis, and the deep SMAS layer. This process quickly tightens stretched collagen, starts muscle tightening, and boosts protein production to help reverse loose skin.
This technology is an upgrade from older systems that needed many slow passes over the skin. It treats both the surface and the deep support layers at once, giving you a non-surgical way to achieve firmer skin.

To tighten loose skin, it’s important to treat all layers, not just the surface. Aging affects the top skin, the collagen in the middle, and the deep SMAS muscle layer. XERF targets all three at once by using two different radiofrequency energies in one session.
The device emits a high-frequency 6.78 MHz wave paired with a deeper 2 MHz wave. The 6.78 MHz frequency treats the upper layers of skin. This action reorganizes thin fibers to improve skin tone, smooth texture, and clear up fine crow's feet. Simultaneously, the 2 MHz frequency bypasses the surface entirely. It drives deep thermal energy into the mid-dermis and down into the SMAS layer. This deep thermal delivery heats the thick connective ligaments and muscular anchors that hold the lower face in position.
The two types of energy cause the skin to react right away. Heat breaks weak bonds in loose collagen, making the fibers contract and tighten the skin quickly. Over the next few months, your body keeps making new collagen and elastin, which strengthens the skin and keeps muscles tight for lasting results.
Our Beverly Hills office uses this advanced technology to address several common areas of skin laxity and texturing flaws across the face and body:

Choosing a non-surgical thermal treatment gives you visible results without the stress or long recovery time of surgery.
This treatment is a good fit for adults with mild to moderate loose skin, early jowls, or sagging neck skin. It is safe for all skin types and tones. It’s also helpful for people who want to keep their facial shape or maintain results from previous surgery. Just remember, results depend on your body’s natural collagen and elastin production, so patience is important.
We do not recommend this treatment for people with very loose skin or significant volume loss. These issues are better treated with surgery or fat injections. If you have a skin infection or open wounds in the area, we will wait until you heal. People with electronic implants such as pacemakers should not have this procedure.

Our treatment process is clean, efficient, and tailored to your skin’s needs. We start by discussing your concerns and creating a personalized plan. A grounding pad is placed on your back or leg to ensure safety during the procedure.
Your provider will apply a clear gel to the treatment areas. The XERF device then moves over your face or neck, sending deep heat followed by a cooling spray. You might feel a brief warmth, especially near the jaw or cheekbones, but most people say it feels like a hot stone massage. No anesthesia is needed, and the session lasts about 30 to 75 minutes. Afterward, the gel is removed and you can go home right away.
Swelling is uncommon. Your skin may look a little pink right after the treatment, but this usually fades within an hour. There is no downtime, so you can get back to your normal activities right away.
You can put on makeup and return to your usual skincare routine right away. Be sure to use a broad-spectrum sunscreen every day to protect your new collagen from sun damage. Drinking plenty of water during the week after your session will also help your skin heal.

The results from dual-frequency treatment last a long time. Most people keep their firmer look for 12 to 18 months. Since aging continues, we recommend a yearly session to help maintain your results.

One session can visibly firm your skin and is a great way to prevent early signs of aging. If you have moderate skin laxity, we suggest two to three sessions, spaced six weeks apart, to build stronger support for your skin.
The cost depends on how large the treatment area is and how long the procedure takes. Treating just the jawline costs less than treating the whole face and neck. We don’t give standard quotes over the phone because every plan is unique. During your free consultation, we’ll create a personalized plan and give you a clear price with no hidden fees. Financing is available through CareCredit and Cherry.
To choose the best treatment for your skin, it’s important to know how different technologies work. At our Beverly Hills office, we look at your skin’s thickness and recommend the options that will work best for you.
Morpheus8 utilizes mechanical insulation needles to puncture the skin barrier, releasing radiofrequency energy directly inside the sub-dermal fat and deep tissue layer. This minimally invasive procedure requires high-potency topical numbing and carries several days of social downtime due to pinpoint bleeding and micro-crusting. XERF delivers its monopolar energy through a completely intact skin barrier, bypassing needles entirely to offer a zero-downtime option without the need for topical anesthetics.
TempSure Envi is a traditional radiofrequency energy system that relies on a single, fixed frequency to apply bulk heat to the mid-dermis. Because it warms only one solitary tissue layer at a time, the volume of treatments required to achieve visible firming is higher. XERF uses dual-frequency technology to manage surface skin texture, midlevel collagen synthesis, and the deep structural anchoring ligaments simultaneously in a single treatment session.
The ContourTRL system is an Erbium:YAG resurfacing laser designed to strip away variable layers of the epidermis to correct deep etched wrinkles and severe sun damage. This laser requires local anesthesia or sedation, followed by weeks of raw skin recovery and wound care. XERF operates beneath the surface layer, leaving the top layer of skin completely undamaged while treating deep structural laxity from within.
A surgical facelift manually cuts and removes loose skin, which yields dramatic results for advanced signs of aging but demands local anesthesia, incisions, and distinct surgical risks. The renuvion procedure passes a plasma beam and helium gas beneath the skin envelope through surgical access ports. XERF avoids incisions, operating entirely on top of the skin barrier to treat mild to moderate jowling safely.

Multifrequency skin tightening works safely alongside other cosmetic procedures. You can receive XERF during the same office visit as your routine neurotoxin injections for forehead wrinkles or crow's feet. It also integrates with dermal fillers; we perform the skin tightening treatment first to firm the tissue matrix before placing volumizing gels to achieve a natural, rejuvenated appearance.

Unlike many clinics that use energy devices as generic tools, we take a personalized approach to skin tightening. We chose XERF because its dual-frequency technology lets us treat different skin layers safely, without causing burns or fat loss. You can meet with our team or Dr. Nazarian’s associates to discuss your goals. Our experts use settings tailored to your skin, so you get natural-looking results that never appear tight or overdone.
No. Older radiofrequency devices could cause unintended fat melting if temperature control failed. XERF uses real-time impedance feedback and automated cooling to keep the thermal energy inside the dermis, midlevel collagen fibers, and structural ligaments. Your protective facial fat pads remain untouched, preserving your natural volume.
Yes. It's safe and effective for all skin tones and ethnicities. XERF relies on radiofrequency energy instead of light-based lasers. Because the energy current ignores skin melanin, the procedure carries an exceptionally low risk of post-inflammatory hyperpigmentation.
None. The built-in surface cooling ensures the epidermis remains undamaged during the pulse. You might experience a slight pink flush for an hour, but you can apply cosmetics and return to your office or social activities right away.
We recommend waiting four to six weeks after filler placement before treating that identical zone with radiofrequency energy. Intense heat can speed up the breakdown of fresh filler gels. Performing XERF first to firm the skin envelope is the preferred clinical sequence.
Traditional devices emit one fixed frequency that concentrates heat within a single depth, usually the upper or mid-dermis. XERF combines a 6.78 MHz frequency and a 2 MHz frequency. This allows the system to tighten surface skin texture and accelerate midlevel collagen production while lifting deeper supportive ligaments near the SMAS layer in a single pass.
