You've Heard of Kybella. But Did You Know Korea Has Its Own Version - V-OLET Injection?
If you are looking for non-surgical ways to address a double chin, you may have encountered names like Kybella and V-OLET (브이올렛). Both treatments center on the same active ingredient: deoxycholic acid (DCA). Because the terminology can be confusing, it is helpful to look at why these treatments exist, how they work, and what distinguishes them in a clinical setting.
The Science of Deoxycholic Acid
Deoxycholic acid is a secondary bile acid that our bodies naturally use to emulsify and break down dietary fat. When injected into localized submental fat (the area under the chin), it functions through a process called adipocytolysis. Rather than simply shrinking fat cells, it disrupts and destroys the fat cell membrane itself. Once these cells are destroyed, the body naturally clears the debris through the lymphatic system, providing a semi-permanent reduction in fat.
What Kybella Actually Is
Kybella is a branded injectable developed by Allergan (AbbVie), approved by the FDA in 2015 for treating submental fat.
Its key ingredient is deoxycholic acid (DCA), a molecule your body already uses to break down dietary fat. When injected under the chin, it works by disrupting fat cell membranes, causing those cells to be permanently eliminated.
Because of its FDA approval and early market presence, Kybella became widely recognized in the US, UK, and Australia as the go-to “double chin injection.”
What Is V-OLET (브이올렛)?
V-OLET is Korea’s MFDS-approved DCA injection, designed for fat reduction in areas like the double chin, jawline, and lower face.
Like Kybella, it uses deoxycholic acid as the active ingredient and works through the same biological mechanism—targeting and breaking down fat cells rather than temporarily shrinking them.
It was approved after Phase 3 clinical trials in Korea, where:
71.6% of participants showed visible improvement
Measurable reductions in submental fat were observed
Safety and efficacy were clinically validated
In practice, this means V-OLET isn’t a substitute or imitation—it’s a locally approved DCA formulation used widely in Korean aesthetic medicine.
Kybella vs. V-OLET: A Functional Comparison
While both products utilize the same core mechanism, they are often used in different regional contexts due to regulatory and distribution patterns.
Feature | Kybella | V-OLET (브이올렛) |
Primary Use | Submental fat reduction | Submental fat reduction |
Regulatory Status | FDA-approved | MFDS-approved (Korea) |
Active Ingredient | Deoxycholic acid (DCA) | Deoxycholic acid (DCA) |
Clinical Goal | Fat cell destruction | Fat cell destruction + collagen support |
Why V-OLET is Common in Korea
In South Korean aesthetic medicine, V-OLET has become a standard choice for jawline contouring. Because it is approved by the Ministry of Food and Drug Safety (MFDS), it allows for a standardized approach to submental fat reduction that aligns with the specific aesthetic goals often sought in Seoul, such as achieving a defined "V-line".
One aspect that differentiates the experience of using V-OLET is its dual-effect design. Beyond the primary goal of destroying fat cells, the clinical protocol for V-OLET is often integrated with a focus on skin elasticity. The inflammatory response that follows the fat reduction process is managed to help stimulate fibroblasts, which may support collagen synthesis in the treated area. This is particularly relevant for those concerned that removing fat might lead to skin laxity under the chin.
Why This Matters for Patients in Korea
If you’re specifically traveling to Seoul for aesthetic treatments, the choice usually isn’t between Kybella and V-OLET—it’s between getting a DCA injection at all, and where.
Korean clinics tend to approach facial contouring more holistically. Instead of treating fat reduction in isolation, DCA injections are often combined with energy-based devices to address both fat and skin laxity in one plan.
For example, a patient with a double chin might receive:
DCA injection to reduce fat volume
Ultherapy or InMode FX to tighten skin
Additional contouring depending on jawline structure
This kind of combination approach can influence how natural the final result looks, especially in the lower face.
What to Expect After Treatment
Side effects are similar across all DCA-based injections, including Kybella and V-OLET:
Swelling (most common; often lasts around 1 week or longer)
Bruising and redness at injection sites
Temporary numbness or tenderness
Because swelling is expected, timing matters—especially for international patients. Many clinics recommend scheduling treatment early in your trip rather than right before departure.
How Many Sessions Are Needed?
The number of sessions depends on how much fat is present and your desired contour.
General patterns:
Clinical studies for Kybella used up to 6 sessions
DCA injections in Korea are often spaced every 3–4 weeks
Many patients begin to see visible changes after 2–3 sessions
A consultation is important here, because under-treating or over-treating the area can affect symmetry and overall facial balance.
Why Patients Look Into DCA Injections in Seoul
Interest in treatments like V-OLET has grown alongside medical tourism in Korea, especially for facial contouring procedures.
Common reasons include:
Access to MFDS-approved DCA treatments
Clinics with high procedural volume and specialization
The ability to combine multiple treatments in a short visit
Cost differences compared to Western markets
Clinics like Forena regularly work with international patients and structure treatment plans around shorter stays, which can be helpful if you’re visiting Korea specifically for aesthetic care.
Frequently Asked Questions
Is V-OLET the same as Kybella? They use the same active ingredient (deoxycholic acid) and work through the same mechanism. V-OLET is a separately approved formulation in Korea.
Can I get Kybella in Korea? Kybella itself is not commonly offered. Instead, MFDS-approved DCA injections like V-OLET are used.
Will results be permanent?Fat cells destroyed by DCA do not return, but remaining fat cells can still expand with weight gain.
Is it safe for foreign patients? Yes, when performed at a licensed clinic with proper consultation and medical screening.
Real Results and Treatment Cost in Seoul
To help patients understand expected outcomes, before-and-after photos are often referenced during consultation or provided as examples of real cases.
Below are examples of V-OLET treatment results at Forena Clinic.
Individual results may vary depending on anatomy, lifestyle, and number of sessions.
V-OLET treatment at Forena Clinic is typically priced based on volume:
2cc — 330,000 KRW per session
4cc — 605,000 KRW per session
Pricing is accurate as of May 2026 and may be subject to change without prior notice.
The required volume and number of sessions vary depending on the amount of fat and treatment area, which are determined during consultation.
Is One Better Than the Other?
For most patients, the better question isn’t “Kybella vs V-OLET,” but:
Is DCA the right treatment for your anatomy?
Is the treatment plan tailored to your face?
Is the practitioner experienced with this specific technique?
Since both products rely on the same active molecule, outcomes tend to depend more on injection design, dosing, and overall treatment planning than on the brand name itself.
Navigating Your Treatment
When considering any injection for fat reduction, the specific brand is only one variable. The safety and efficacy of the procedure are heavily dependent on the provider’s expertise. Proper assessment is required to ensure that the patient’s "double chin" is truly caused by excess fat rather than skin laxity or anatomical bone structure, which would require different treatment approaches.
At Forena Clinic, we emphasize an evidence-based approach to contouring. We prioritize a thorough consultation to determine if you are a candidate for deoxycholic acid injections or if your aesthetic goals are better met through other non-surgical skin tightening or contouring modalities. We invite you to visit our clinic in Seoul for a personalized assessment to discuss whether V-OLET fits into your treatment plan.
