NUVIJU
A localized fat improvement injection that directly targets submental fat with cholic acid

ABOUT
What is NUVIJU?
- 01
Approved as Korea’s 40th domestically developed new drug, this prescription injectable uses cholic acid, a bile acid found in the body, as its main ingredient to precisely reduce subcutaneous fat.
- 02
Compared with conventional deoxycholic acid (DCA), it reduces harmful effects and uses a pH formulation similar to that of the human body, providing consistent fat-dissolving effects while reducing pain and swelling after treatment.
- 03
Having met the rigorous clinical standards for a domestically developed new drug, it allows personalized contour design tailored to each person’s fat structure through fine adjustments to injection volume and layer.
HOW IT WORKS
How does it work?
It promotes natural fat reduction in the injected area.
It triggers adipocytolysis by dissolving the lipid bilayer of fat cell membranes.
The destroyed fat cells are naturally eliminated through the body’s own metabolic processes, creating smooth, clearly defined contours.
WHERE IT WORKS
Precisely injected into the subcutaneous fat layer beneath the chin and in the double-chin area, it promotes fat cell dissolution and natural elimination.

RECOMMENDED FOR
Who is this treatment for?
- 01
For those seeking consistent cholic acid-based reduction of under-chin fat with significantly less pain and swelling than conventional DCA (deoxycholic acid) injections
- 02
For those seeking selective removal of subcutaneous fat beneath the chin and in the double-chin area that is difficult to lose through diet or weight loss alone
- 03
For those seeking to destroy and eliminate fat cells with nonsurgical injections that reduce pain and swelling, without the burden of surgical liposuction
- 04
For those seeking to refine the boundary between the jawline and neck blurred by under-chin fat buildup, for clearer, smoother contours
TREATMENT AREAS
Main treatment areas
- Under-chin fat
- Double-chin area
The actual treatment area is determined during consultation based on facial structure, skin condition, and the product used.
The image is an illustration to help explain the area and does not represent an individual’s treatment results.
BENEFITS
Changes you can expect
- 01Improvement of double-chin and lower-face contours through selective dissolution of the subcutaneous fat layer beneath the chin
- 02Nonsurgical treatment to dissolve localized fat using injections without an invasive surgical procedure
- 03Restoration of a clearly defined boundary between the chin and neck by reducing the thickness of the under-chin fat layer
- 04Smoother frontal and profile contours through a reduction in lower-face soft tissue volume
KEY POINTS
Key treatment points
- 01Uses cholic acid, a domestically developed new drug ingredient, to directly destroy fat cell membranes through adipocytolysis
- 02Establishes a personalized treatment plan after anatomical assessment of whether there is fat accumulation alone or accompanying skin laxity
- 03Ensures safety by precisely administering the product into localized subcutaneous fat beneath the chin while minimizing damage to surrounding normal tissue
RESULT JOURNEY
How the results develop over time
Immediately after treatment, swelling and tenderness may appear before fat reduction becomes visible. Over the weeks after the initial response settles,
under-chin volume and contours gradually become more refined, and repeat treatments may be planned depending on the amount of fat.
INEE APPROACH
INEE’s approach to this treatment
- 01
We first assess facial expressions and proportions to select the areas that actually need enhancement.
- 02
We plan the amount and placement needed based on the product’s characteristics and the condition of the skin and tissue.
- 03
We aim for results that naturally bring out your original appearance and balance, rather than excessive volume.
RECOVERY & CARE
What to check before and after treatment
Before treatment
The first step is to assess whether a prominent under-chin area is caused by actual fat volume or sagging skin. During consultation, tell us about any recent under-chin filler, thread lifting, or HIFU treatments.
Immediately after treatment & recovery
Localized fat-reduction injections may cause swelling, warmth, bruising, and tenderness at the treatment site, so allow for recovery before important events. Recovery varies with the injection volume and individual response.
Aftercare
Avoid pressing or irritating the injection site excessively, and avoid alcohol, saunas, and vigorous exercise for the period advised by the medical team.

NEXT STEP
