Real Patient Results from WooYoo Medical Aesthetics in Los Angeles
XERF is an advanced monopolar radiofrequency (RF) skin tightening treatment designed to improve the jawline, lower face, neck, and overall skin firmness without surgery. By stimulating collagen remodeling, XERF can help create a more defined facial contour while also improving skin texture and elasticity.
In this article, we share real before-and-after results from patients in their 30s, 40s, and 50s who received XERF treatments at WooYoo Medical Aesthetics in Los Angeles. These cases demonstrate how treatment plans are customized based on each patient's age, facial anatomy, and aesthetic goals.
As an Official XERF Provider, WooYoo Medical Aesthetics has performed more than 500 XERF treatments (as of July 2026). Because treatment techniques and energy settings are customized for each patient, results can vary depending on age, skin laxity, facial anatomy, and the number of sessions performed. Every provider on our team has completed official manufacturer training and certification, and we continue to receive advanced education in Korea to stay current with the latest treatment techniques.
Rather than showcasing only ideal marketing images, we believe in sharing real patient outcomes. The three cases below illustrate what patients can realistically expect after one or two XERF treatments—from subtle jawline contouring in younger patients to noticeable lifting and skin tightening for more advanced signs of aging.
How Does XERF Work?
XERF is an advanced monopolar radiofrequency (RF) skin tightening treatment developed in Korea.
Unlike surgery, XERF stimulates collagen remodeling while simultaneously tightening the deeper support structures of the face.
Many patients choose XERF because it can improve:
Jawline definition
Double chin appearance
Lower face contour
Nasolabial folds
Marionette lines
Sagging cheeks
Neck laxity
Skin texture
Enlarged pores
Acne scars
Overall skin firmness
One of the biggest advantages of XERF is that it creates both lifting and skin quality improvements at the same time.
Real XERF Before & After Case #1
Bride-to-Be in Her 30s
600 Shots | Full Face | One Treatment
Patient Goal
This patient was preparing for her wedding.
She wasn't concerned about severe skin laxity.
Instead, her goal was:
A slimmer face
Better jawline definition
More photogenic facial contours
A sharper V-line for wedding photos
Treatment
We performed:
Full face XERF
600 shots
Focused primarily on the lower face and jawline
Rather than aggressively treating the upper face, we customized the treatment to maximize facial contouring.
Results After One Session
Even after just one treatment, the changes were immediately noticeable.
Compared to the before photos:
Unnecessary lower face volume appeared reduced
The jawline became significantly sharper
Facial contours appeared more defined
The overall face looked slimmer
The V-line became much more visible
This is one of our favorite examples showing that XERF isn't only for anti-aging.
It can also be an excellent treatment for younger patients who simply want a more sculpted facial shape without surgery.
Real XERF Before & After Case #2
Patient in Her 40s
Face + Neck | 900 Shots | One Treatment
Treatment
This patient received:
XERF Face + Neck
900 shots
Chin filler for additional lower face projection
Combining XERF with chin filler created stronger facial balance while allowing the RF treatment to improve skin support.
What Improved?
The most noticeable improvements included:
Significant improvement in Mid-cheek grooves (often called "Indian bands")
The volume loss and indentation across the anterior cheeks became much softer, creating a smoother transition between the cheeks and mid-face.
Softer nasolabial folds
As collagen remodeling occurred, the nasolabial folds became less pronounced without surgery.
Sharper jawline
The lower face appeared tighter with improved contour.
Better skin quality
One of the most interesting findings wasn't just the lifting.
The patient's skin itself looked healthier.
We observed:
Brighter skin tone
Smaller-looking pores
Improved skin texture
Acne scars appearing less noticeable
This is something we've consistently seen in many XERF patients.
As collagen production increases, improvements often extend beyond lifting to overall skin quality.
Many of our patients mention that friends notice their skin looks healthier—even before realizing they had a lifting treatment.
Real XERF Before & After Case #3
Patient in Her 50s
Face + Neck | 900 Shots × 2 Sessions
One Month Apart
Treatment
This patient received:
Face + Neck XERF
900 shots per treatment
Two sessions
Four weeks apart
Results
Compared with the initial photos, improvements were dramatic.
We observed noticeable improvement in:
Nasolabial folds
Marionette lines
Double chin
Neck wrinkles
Lower face heaviness
Jawline definition
Sagging jowls
The facial contour became much smoother, and the heaviness along the jawline improved significantly.
The patient described the results as feeling like she had undergone a non-surgical facelift without the downtime or risks associated with surgery.
This case also demonstrates why multiple treatments can produce progressively stronger collagen remodeling, especially in patients with moderate to advanced skin laxity.
Patient | Age | Treatment | Sessions | Main Improvement |
Case 1 | 30s | Full Face 600 Shots | 1 | V-line, slimmer jawline |
Case 2 | 40s | Face + Neck 900 Shots | 1 | Mid-cheek grooves, nasolabial folds, skin texture |
Case 3 | 50s | Face + Neck 900 Shots | 2 | Jowls, marionette lines, neck wrinkles |
Why Do XERF Results Improve Over Time?
Unlike fillers, XERF doesn't simply add volume.
Instead, it stimulates your body's natural collagen remodeling process.
Patients often notice:
Immediately
Slight lifting
Better jawline definition
Reduced facial puffiness
1–3 Months
Increased skin firmness
Continued lifting
Improved facial contour
Better skin texture
3–6 Months
Peak collagen production
Long-lasting tightening
Improved elasticity
Natural rejuvenation
Because collagen remodeling takes time, many patients continue seeing improvement well after their treatment.
Who Is a Good Candidate for XERF?
XERF works well for patients who want:
A slimmer jawline
Non-surgical facial lifting
Skin tightening
Double chin improvement
Neck tightening
Better skin elasticity
Reduced jowls
Improved nasolabial folds
Better skin texture
Smaller-looking pores
It is suitable for patients in their 30s through their 60s and can be customized according to facial anatomy and treatment goals.

Frequently Asked Questions
Does XERF work after one treatment?
Many patients notice an immediate improvement in jawline definition and skin tightness after one session, with collagen remodeling continuing for 3–6 months.
How many XERF treatments do I need?
Patients in their 30s often see excellent results with one treatment. Moderate skin laxity typically benefits from 2–3 sessions, while advanced laxity may require additional treatments.
Is XERF painful?
Most patients tolerate the procedure well with topical numbing cream. Energy levels are customized according to skin thickness and treatment area.
How long do XERF results last?
Results generally continue improving for several months and can last around 8–12 months depending on age, collagen production, and lifestyle.
Is XERF better than Ultherapy?
XERF and Ultherapy target different tissue layers and can complement each other. The best treatment depends on your skin condition, anatomy, and treatment goals.
When will I see my final XERF results?
Many patients notice an immediate improvement in facial contour after treatment, but collagen remodeling continues for approximately 3–6 months. Final results typically become more noticeable several weeks after the procedure.
