QD V-Cut Injectionin Gangnam, Seoul

QD V-Cut is a lipolytic (“fat-dissolving”) injection used to refine the lower-face contour — the under-chin area, jawline and lower cheeks — by breaking down small, localized pockets of fat. At QD Clinic in Gangnam, Seoul, we first assess your face shape and whether the fullness comes from fat, muscle or bone, then plan the injection points and number of sessions. A session usually takes about 15–20 minutes with little downtime. (Results vary by individual.)

Injection points are planned after assessing whether the fullness is fat, muscle or bone.

Who it’s for

  • A soft double chin or fullness under the jaw from localized fat
  • Fullness along the lower cheeks or jowl area
  • A jawline you would like to look more defined without surgery
  • Anyone who prefers a non-surgical, injection-based option

V-Cut addresses fat, not muscle or bone. If the fullness comes from a developed jaw muscle or the bone shape, other options such as masseter Botox are discussed. Suitability is confirmed at consultation.

How it works

The injection places a lipolytic solution into small, targeted fat deposits. Its active ingredients — such as deoxycholic acid, a bile acid the body also produces — work at the membrane of fat cells so the fat is broken down and then cleared gradually through the body’s natural metabolic and lymphatic processes over the following weeks. As the area settles, some people also notice firmer-looking skin. The exact formulation, points and dose are planned for your anatomy at consultation.

THE MECHANISM, STEP BY STEP

  • 01Placed, not spread

    The lipolytic solution is injected into small, mapped fat pockets under the chin and along the jawline — not applied broadly — so it acts where the fullness actually sits.

  • 02Acting at the fat-cell membrane

    Active ingredients such as deoxycholic acid, a bile acid the body also makes, work at the membrane of fat cells in the treated spot so the fat is broken down.

  • 03Cleared by the body

    The released fat is carried away through the body’s natural metabolic and lymphatic processes over the following weeks, which is why the contour change is gradual rather than immediate.

  • 04Built over a few sessions

    Each session treats a limited amount, so the line is refined step by step across several visits rather than all at once. (Results vary by individual.)

What the procedure is like

  1. 1Consultation and assessment of face shape and fat distribution
  2. 2Cleansing and marking of injection points
  3. 3Fine-needle injection of the lipolytic solution
  4. 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, warmth, redness or mild bruising may occur for a few days, and swelling under the chin 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.

  1. DAY 0 Treatment day

    A brief stinging as the solution is injected, then warmth, redness and swelling under the chin. Most people return to daily activities the same day.

  2. 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.

  3. WEEK 2-4 Fat clears

    As the treated fat is gradually cleared, some people start to notice a cleaner line. This varies a lot from person to person.

  4. NEXT SESSION Repeat as planned

    A further session is usually scheduled a few weeks later to build the change gradually. (Results vary by individual.)

  5. ~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 several sessions is common — often about 2–4 — spaced a few weeks apart, with the contour refining gradually as the treated fat clears and swelling settles. Your plan and the interval are decided at consultation, and maintaining a stable weight helps hold the result. (Results vary by individual.)

How it compares

These options all refine the lower-face line, but they address different tissue, so the right one depends on whether the fullness is fat or muscle.

Safety & considerations

Possible reactions

  • Temporary swelling under the chin, which can be noticeable in the first days
  • Tenderness, warmth or redness in the treated area
  • Mild bruising at injection points
  • A firm feeling or small lumps that usually settle over time
  • Rarely, temporary numbness in the area that typically recovers

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

QD V-Cut addresses fat, not muscle or bone, and it is not a weight-loss treatment. Whether it suits you is confirmed during consultation. Effects and downtime vary by individual, and side effects may occur.

Frequently asked questions

  • Yes — it is a lipolytic (fat-dissolving) injection used to break down small, localized fat in the lower face. The formulation and plan are decided at consultation. (Results vary by individual.)

  • A brief stinging or pinching can occur as the solution is injected, and the area may feel warm or swollen afterward. Comfort options are discussed at consultation.

  • It appears gradually over a few weeks as the treated fat clears and swelling settles, usually across several sessions. (Results vary by individual.)

  • V-Cut breaks down fat, while masseter Botox relaxes the chewing muscle. If your fullness is muscle rather than fat, Botox may suit better, and sometimes they are combined. This is decided at consultation.

  • The fat broken down in the treated area is cleared by the body; maintaining a stable weight helps hold the contour, though remaining fat cells can still change with weight gain. (Results vary by individual.)

  • Little to none. Temporary swelling under the chin, tenderness or mild bruising may occur and usually settles within a few 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.
