What is v-olet
V-OLET is a high-concentration contouring injection specifically designed to target submental and double-chin fat. It contains deoxycholic acid (DCA), which works by disrupting the membranes of fat cells, helping reduce localized fat and refine the appearance of the jawline.
Unlike treatments that simply reduce the size of fat cells, V-OLET works by eliminating targeted fat cells. This process may also support collagen production, helping maintain skin elasticity and minimize the appearance of sagging for a firmer, more defined contour beneath the chin.

Completing Clear Facial Lines Through Continuous Fat Reduction
- POINT 01.
A Precision Fat-Reduction SolutionUnlike conventional contour injections that reduce the size of fat cells, v-olet directly destroys fat cell membranes to reduce the number of cells, providing semi-permanent effects after treatment. Additionally, to prevent loss of skin elasticity after the procedure, v-olet induces collagen production and improves both the fat and skin layers simultaneously, making it possible to create clearer and more defined contours.
- POINT 02.
Nana Dermatology's V-Violet v-oletis the only fat improvement injection approved by the Korea Food and Drug Administration (KFDA). The main ingredient of v-olet deoxycholic acid (DCA), is a secondary bile acid that naturally exists in the body and works to emulsify and decompose fat.

v-olet Q&A
- There may be pain after the procedure, and discomfort may be felt 30 minutes to 1 hour after treatment. While it is a manageable level of pain, pain sensation varies from person to person. If pain is severe, taking acetaminophen may help. Nana utilizes various pain relief methods (numbing cream, nerve block anesthesia, pain management IV, etc.) and offers sedation anesthesia to reduce concerns about pain.
- Swelling and bruising may occur after the procedure and can persist for several days. Swelling can last from 2 to 4 weeks depending on the individual.
- V-OLET typically provides results that last approximately 6 months to 1 year or longer. As it works by targeting and destroying fat cells themselves, the effects may be long-lasting in principle. After a single treatment, results generally remain noticeable for 6 months to 1 year or longer, although individual outcomes may vary. For optimal results, a series of 2–3 treatments spaced approximately 4 weeks apart is generally recommended.
