V-Line Slimming Injections in Seoul: Jaw Botox & Contouring
A non-surgical plan combining masseter Botox, fat-dissolving injections and optional chin filler for a slimmer lower face.
V-line slimming injections combine masseter-relaxing Botox with optional fat-dissolving injections and chin filler to narrow a wide lower face and define the jawline. A visit takes about 15–20 minutes and most people return to normal activities immediately, with brief mild swelling possible. Masseter slimming starts in 2–4 weeks, reaches full effect at 6–8 weeks and lasts about 4–6 months; fat reduction appears in 3–6 weeks.
What are V-line slimming injections?
V-line slimming is a customised, non-surgical plan for the lower face. Depending on your anatomy it may combine:
- Masseter Botox to relax and gradually slim bulky jaw muscles ( masseter Botox)
- Fat-dissolving injections for lower-cheek fullness or a mild double chin ( fat-dissolving injections)
- Chin filler(optional) to improve the chin-to-jaw ratio ( chin fillers)
Who is a good candidate?
- Square or wide jawline from bulky masseter muscles
- Lower-cheek fullness or a mild double chin
- Soft or undefined jawline, or a short, receding chin
Bone-related width and significant skin laxity are not corrected by injections; lifting treatments may be combined for sagging.
Real result: Jawline / side-cheek volume (masseter & cheek filler)
Masseter-relaxing injections slim the lower face gradually; the full contour change appears after about 6–8 weeks.
