Wonder-V
Wonder-V is a deoxycholic acid (DCA) injection for excess fat beneath the chin in adults. At QD Clinic, consultation first distinguishes fat from loose skin, muscle and skeletal shape, then plans the treatment area and recovery schedule.
Wonder-V is available at QD Clinic in Gangnam, Seoul, Korea.

is this for me
Who it’s for
Even if none of these describes you, we will look again at the consultation.
- Adults with a double chin caused by local fat deposits
- People considering a nonsurgical option for under-chin fat
- People able to allow time for visible swelling and follow-up
This is not a weight-loss or skin-lifting treatment. Little fat, marked skin laxity or a mainly muscular or skeletal concern may call for a different approach. Results and recovery vary.
start with your concern
Before you pick a treatment name, start with the cause of your concern.
Even a treatment with the same name takes on a different role and scope depending on your current structure, the change you want, what you have had before and the recovery time you have.
Where you are now, and where we start
Assessing under-chin fat separately from loose skin
The change you want, the impression you keep
Assess fat thickness and distribution, skin elasticity and symmetry; review previous procedures, medicines and any swallowing difficulty.
How it differs from similar options
This is not a weight-loss or skin-lifting treatment. Little fat, marked skin laxity or a mainly muscular or skeletal concern may call for a different approach. Results and recovery vary.
Health information and recovery schedule
The product instructions allow up to six sessions at least one month apart. Six sessions are not necessary for everyone; response and goals guide the plan. A single-session result or a permanently unchanged jawline is not guaranteed.
the principle
How it works
Act on fat cells
Chong Kun Dang’s Wonder-V contains deoxycholic acid 20 mg/2 mL. Its Korean indication is moderate to severe protruding or excess submental fat in adults. This does not establish approval for the cheeks, jowls or body. Deoxycholic acid disrupts fat-cell membranes. Contour changes can develop as the damaged cells are cleared; the early inflammatory response may cause swelling and firmness.

How it works
Identify the cause
Assess fat thickness and distribution, skin elasticity and symmetry; review previous procedures, medicines and any swallowing difficulty.
Act on fat cells
Deoxycholic acid disrupts fat-cell membranes. Contour changes can develop as the damaged cells are cleared; the early inflammatory response may cause swelling and firmness.
Plan the treatment
Map the target fat and areas to avoid around nerves and glands. Discuss the product, expected amount, cost and reassessment timing.
Reassess after recovery
Once swelling settles, compare photographs at the same angle and reassess in person. Further treatment depends on remaining fat and recovery.
the qd standard
The same treatment, never the same plan.
Rather than a fashionable name or a fixed package, we weigh the structure found at examination, safety, recovery and the limits within one plan.
- DIAGNOSIS FIRST
Cause before name
We first separate out the tissue and the function behind your concern.
- LESS, PRECISE
Only as much as needed
Rather than an excessive change, we plan the smallest scope with a clear role.
- HONEST LIMIT
The limits, explained too
We explain the change you can expect, the alternatives, individual differences and the risks.

What the procedure is like
- Assess fat thickness and distribution, skin elasticity and symmetry; review previous procedures, medicines and any swallowing difficulty.
- Map the target fat and areas to avoid around nerves and glands. Discuss the product, expected amount, cost and reassessment timing.
- After cleansing and appropriate comfort measures, the clinician injects the planned subcutaneous fat beneath the chin.
- Follow the cooling and care instructions provided; avoid forceful self-massage. Plan important events and travel around possible swelling and access to follow-up.
Visit length depends on the area, anesthesia and observation needed. Confirm time for consultation and aftercare when booking.
Please read this before treatment
- Swelling, tenderness, bruising and redness may initially make the chin look fuller. The immediate appearance is not the final contour.
- Swelling, numbness and firmness can persist for weeks. Returning to routine activities and looking fully settled are different milestones.

how it compares
How it compares
Wonder-V and V-Olet both use deoxycholic acid for submental fat, but are different products. Check each product’s instructions and planned amount; the brand alone does not establish better results or less pain.
| Wonder-V | V-Olet | Jaw Botox | |
|---|---|---|---|
| Ingredient / action | DCA 20 mg / 2 mL | DCA | Botulinum toxin |
| Main target | Submental fat | Submental fat | Enlarged masseter muscles |
| Selection | Assessing under-chin fat separately from loose skin | Assessing under-chin fat separately from loose skin | Jaw Botox reduces the activity and bulk of enlarged chewing muscles. It addresses a different cause of fullness from fat-cell treatment beneath the chin. |

Your quote follows assessment of the area, expected vial count and sessions. Confirm the product, amount, tax and follow-up inclusions. Comparing cc alone across contouring injections can be misleading.
Look at the examination and the plan rather than the treatment name. First, what the clinic checks before deciding — at QD Clinic in Gangnam, Seoul, the first thing we look at for this treatment is “Assessing under-chin fat separately from loose skin”. Second, whether it explains why it recommends that scope and method, compared with the alternatives. Third, whether it reviews your progress with you when results are expected. Our doctor goes through these three points at consultation before the treatment is decided.
