V-Line Slim Injection — Better Body Fit at VOS Dermatology Clinic, Gangnam Seoul

Overview

The V-Line Slim Injection in Seoul is a fat-cell-targeting injectable for submental fat — the double chin — described by the clinic as the only FDA-approved injectable for this purpose available in Korea. Its main ingredient, deoxycholic acid, is a naturally occurring bile acid that breaks down fat by destroying fat-cell membranes under the chin.

At VOS Dermatology in Gangnam it is used to improve a double chin and an undefined jawline while improving skin elasticity. A session is completed within 30 minutes, no anaesthesia is required and you return to daily activities immediately; mild swelling for 1–2 days is possible and results vary from person to person.
