Unlike ordinary injections that temporarily reduce only the size of fat cells, this treatment directly destroys fat cell membranes, permanently reducing the number of fat cells.
By promoting collagen synthesis in the space where fat has been removed, it helps prevent skin sagging after fat reduction and creates a firmer jawline.

Deoxycholic acid, or DCA, the main ingredient of V Injection, is a secondary bile acid naturally present in the body that helps emulsify and break down fat.

General contour injections reduce the size of fat cells, while V Injection destroys fat cells and reduces the number of fat cells.
It also helps induce collagen synthesis, supporting the maintenance and improvement of skin elasticity.

A submental fat improvement of at least one grade was confirmed in 71.6% of patients treated with V Injection.


V Injection is recommended 2–3 times at intervals of at least one month.
The treatment takes about 10–20 minutes, and you can return to daily life immediately afterward.
You can see improvement in double chin starting about one month after treatment.
Pain, swelling, and mild bruising may occur after treatment, but these symptoms usually disappear naturally.
However, please note that swelling may last for more than one week due to the fat cell destruction effect of DCA.
Swelling occurs during the key process of DCA: “fat cell destruction - removal of fat cell debris - induction of collagen synthesis.”
It is also best to avoid high-temperature stimulation after treatment, such as saunas, steam rooms, hot baths, and hot packs.
