V-Olet Contour Injectionin Gangnam, Seoul
V-Olet is a fat-dissolving contour injection based on deoxycholic acid (DCA), a bile acid the body also produces. It is used to soften small pockets of fat under the chin and along the jawline for a cleaner lower-face line. V-Olet is a deoxycholic-acid injection approved in Korea by the Ministry of Food and Drug Safety (MFDS) for reducing under-chin (submental) fat. At QD Clinic in Gangnam, Seoul, we assess your contour first, then plan the points and sessions. A session usually takes about 15–20 minutes with little downtime. (Results vary by individual.)
Who it’s for
- A soft double chin or fullness under the jaw from localized fat
- A jawline you would like to look cleaner and more defined
- Small fat pockets rather than sagging skin or muscle bulk
- Anyone who prefers a non-surgical, injection-based option
V-Olet targets fat, not loose skin or muscle. If skin laxity or a jaw muscle is the main concern, we may suggest a lifting or Botox option instead or alongside. Suitability is confirmed at consultation.
How it works
Deoxycholic acid works at the membrane of fat cells in the injected area. The fat is broken down and then cleared gradually through the body’s natural metabolic and lymphatic processes over the following weeks, while the mild healing response can encourage the skin to look firmer. Because it acts locally, precise placement matters, so the points and dose are mapped to your contour. Several sessions are usually planned to build the change gradually.
THE MECHANISM, STEP BY STEP
01A deoxycholic-acid solution
V-Olet places a solution based on deoxycholic acid (DCA) — a bile acid the body also produces — into small pockets of fat under the chin and along the jawline.
02Acting at the fat-cell membrane
DCA works at the membrane of fat cells in the treated area so the fat is broken down locally, which is why precise placement matters.
03Cleared by the body
The released fat is removed through the body’s natural metabolic and lymphatic processes over the following weeks, so the line refines gradually rather than at once.
04A mild firming response
As the area heals and settles, the skin can also look a little firmer — though the main action is on fat, not skin laxity. (Results vary by individual.)
Treatment areas
- Under-chin (submental)
- The double-chin area — the primary use for V-Olet.
- Jawline
- Along the lower jaw for a cleaner contour.
- Lower cheeks
- Small localized fullness, decided at consultation.
What the procedure is like
- 1Consultation and assessment of the lower-face contour
- 2Cleansing and marking of injection points
- 3Fine-needle injection of the deoxycholic-acid solution
- 4Brief pressure, cooling and aftercare guidance
Time: A session takes about 15–20 minutes.
Recovery & aftercare
- Little to no downtime; most people return to daily activities the same day.
- Temporary swelling, tenderness, firmness, redness or mild bruising may occur for a few days, and a temporary numb feeling under the chin can occur; swelling can be noticeable at first.
- Follow the aftercare guidance we provide, and let us know about any concerns between sessions.
What to expect over time
A general guide to how the days and months after treatment usually unfold. Results vary by individual.
DAY 0 Treatment day
A brief stinging during injection, then warmth and swelling under the chin; a temporary numb feeling can occur. Most people return to daily activities the same day.
DAY 1-7 Swelling settles
Swelling under the chin is often most noticeable in the first days; tenderness, firmness or mild bruising may occur and generally eases through the week.
WEEK 2-4 Fat clears
As the treated fat is gradually cleared, some notice a cleaner line. This varies from person to person.
EVERY 3-4 WEEKS Next session
Sessions are usually spaced about 3–4 weeks apart to build the change gradually. (Results vary by individual.)
~2-3 MONTHS Review
After the course, your doctor reviews the contour and discusses whether any further session is helpful. (Results vary by individual.)
Sessions & results
A course of about 2–4 sessions spaced roughly 3–4 weeks apart is common, with the contour refining gradually as the treated fat clears. Your plan is decided at consultation, and a stable weight helps maintain the line. (Results vary by individual.)
How it compares
These options all refine the under-chin and jawline, but they address different tissue, so the right one depends on the cause of the fullness.
| Comparison | V-Olet | QD V-Cut Injection | Masseter Botox |
|---|---|---|---|
| Approach | Fat-dissolving injection (deoxycholic acid) | Fat-dissolving injection (clinic protocol) | Muscle-relaxing injection |
| Targets | Under-chin fat | Small localized fat | The masseter (chewing) muscle |
| Often chosen for | Under-chin fat with an MFDS-approved product | Under-chin and jawline fat | Fullness from a developed jaw muscle |
| Sessions | Usually a short course | Usually a short course | Periodic; effect is temporary |
| Downtime | Little; temporary swelling | Little; temporary swelling | Little to none |
Neither is “better” — they work differently and suit different goals. The right choice is decided after we assess your skin.
Safety & considerations
Possible reactions
- Temporary swelling under the chin, which can be noticeable in the first days
- Tenderness, firmness, warmth or redness in the treated area
- Mild bruising at injection points
- A temporary numb feeling under the chin that usually recovers
- Rarely, an uneven or nerve-related sensation that typically settles
When to take extra care
- Pregnancy or breastfeeding — let us know at consultation
- Active infection, inflammation or skin problems in the treatment area
- A bleeding tendency or use of blood-thinning medication — tell your doctor
- Recent fillers, threads or other treatments in the area — so timing can be planned
- A history of keloid or difficulty with wound healing
V-Olet targets fat, not loose skin or muscle, and its Korean approval is for under-chin fat. Whether it suits you is confirmed during consultation. Effects and downtime vary by individual, and side effects may occur.

Frequently asked questions
Its main ingredient is deoxycholic acid (DCA), a bile acid the body naturally produces that helps break down fat. It is a deoxycholic-acid injection approved in Korea by the MFDS for reducing under-chin fat. (Results vary by individual.)
Both are fat-dissolving injections for the lower face. V-Olet is a specific deoxycholic-acid product, while QD V-Cut is our clinic protocol; the right choice and plan are decided at consultation.
A brief stinging and a warm, swollen feeling under the chin can occur. Comfort options are discussed at consultation.
Often about 2–4, spaced a few weeks apart, decided at consultation as the contour refines gradually. (Results vary by individual.)
It targets fat rather than skin laxity, though the skin may look a little firmer as the area settles. For loose skin, a lifting option may suit better. This is decided at consultation.
Little to none. Temporary swelling under the chin, tenderness or mild bruising may occur; swelling can be noticeable in the first days.
Yes. Our doctors consult in English directly, and 中文 / 日本語 can be arranged in advance. Tell us your language on WhatsApp before your visit.
Often considered together
Treatments that are sometimes planned alongside this one, decided at consultation.
+Masseter Botox
If part of the fullness comes from a developed chewing muscle, relaxing the masseter can be planned alongside fat reduction. Sequencing is decided by your doctor.
+Lifting treatments
When skin laxity accompanies the fat, an energy-based lifting treatment may be discussed to address firmness that fat reduction alone does not.
+Skin boosters
Injectable hydration and skin-quality treatments address surface texture and glow, which contouring does not target.
