Seo-hee Jang, a popular Korean actress who played Ya Mars in the TV series Miss Mermaid, used drug injection to correct and reshape her chin. The chin correction surgery she received was to paralyze the muscles in this area first, and then cut the bone to remove the damaged area. The advantage of the operation is that it is painless and can have a beautiful chin. It is through natural advantages and corrected chin that Seo-hee Jang perfectly interprets the gentle image of "beauty in all directions".
