Dermatology ClinicJawline Slimming in Busan, Korea A slimmer, more defined lower face, matched to what is making it look wide
A wide lower face can come from strong jaw muscles, soft fullness, sagging or a short chin, and each needs a different fix. At JRYN Seomyeon the doctor finds the cause first , then plans Botox, RF contouring, filler or lifting, alone or combined.
How can I slim my jawline without surgery?
The most common non-surgical option is Botox in the masseter (jaw) muscles. It relaxes an enlarged muscle so it gradually becomes smaller, which softens a square jaw over several weeks. If the width is due to fullness, RF contouring can help; if it is due to sagging, lifting is used; and a little chin filler can make the lower face look longer and slimmer. Many people need a combination.
At JRYN Seomyeon, square-jaw Botox is listed from ₩15,000 (Korean toxin, Newlux), with Coretox ₩35,000 , Dysport ₩90,000 and Allergan 50U ₩139,000 . Dr. Yoon Jung-wook confirms the plan and dose at consultation.

Jawline Slimming FAQ

How much is jawline slimming Botox at JRYN?
Square-jaw Botox is listed at ₩15,000 with Korean toxin (Newlux), ₩35,000 with Coretox, ₩90,000 with Dysport and ₩139,000 with Allergan 50U. Your doctor confirms the brand and dose before treatment.
How long until my jaw looks slimmer?
Botox starts relaxing the muscle within about a week, but the slimming itself appears gradually over about 2 to 4 weeks as the muscle becomes smaller. If you are visiting, you will usually see the full effect after you return home.
How long does jaw Botox last?
Results often last several months, though it varies with dose, muscle strength and habits such as clenching. Repeat treatments are usual; some people find they need them less often over time.
Will jaw Botox change how I chew?
Chewing can feel slightly weaker for a few weeks, especially with tough or chewy food. Normal eating is not affected for most people. Your doctor adjusts the dose to balance slimming and comfort.
Can Botox fix a wide jaw caused by bone?
No. Botox only reduces muscle bulk. If the width is mainly bone, the change will be limited. The doctor can tell at the examination and may suggest chin filler to improve proportions instead.
Is jawline slimming different from jawline lifting?
Yes. Slimming reduces width, usually by shrinking the jaw muscle. Lifting tightens sagging skin so the jawline looks sharper. Some people benefit from both; see our jawline lifting guide.
Can I combine jaw Botox with other treatments on the same day?
Often, yes. Common combinations are chin filler, InMode FX for fullness, or a lifting treatment. Your doctor plans the order and checks that the combination suits your schedule.
