Dermatology ClinicCheek Slimming Injections in Busan, Korea A slimmer lower face starts with the right diagnosis: jaw muscle, cheek fat or sagging
Full cheeks can come from a strong jaw muscle, extra fat or loose skin, and each needs a different injection. At JRYN Seomyeon, your doctor checks which applies to you and confirms the price before treatment .
What are cheek slimming injections?
Cheek slimming injections are non-surgical injections that make the lower face look slimmer. The most common is Botox in the masseter (jaw) muscle, which gradually reduces a square or bulky jawline. When the fullness is fat rather than muscle, fat-dissolving injections may be used instead, and when it is sagging, lifting usually works better.
At JRYN Seomyeon, square-jaw Botox starts from ₩15,000 with Korean toxin (Newlux), with Coretox, Dysport and Allergan also available. Fat-dissolving injections are priced after your doctor assesses the area.
Cheek slimming at a glance
| What it treats | A square or wide jaw, bulky lower cheeks, mild facial fullness and asymmetry from a stronger muscle on one side |
|---|---|
| Muscle-based fullness | Masseter Botox relaxes the jaw muscle so it slowly becomes smaller |
| Fat-based fullness | Fat-dissolving injections target small pockets of fat, usually over a few sessions |
| Sagging cheeks | Injections that slim will not lift. Lifting such as InMode or HIFU may suit better. |
| When you see results | Jaw Botox: slimming shows from about 2 to 4 weeks and peaks at around 6 to 8 weeks |
| How long it lasts | Jaw Botox often lasts around 4 to 6 months. Repeated treatment can keep the muscle smaller for longer. |

How much are cheek slimming injections in Busan?
At JRYN Seomyeon, square-jaw Botox costs ₩15,000 with Korean toxin (Newlux), ₩35,000 with Coretox, ₩90,000 with Dysport and ₩139,000 for Allergan 50U. Fat-dissolving injections are priced after the doctor assesses the area.
Do cheek slimming injections reduce fat?
Jaw Botox does not remove fat. It shrinks the masseter muscle, which is often the real cause of a wide lower face. If your fullness is fat, your doctor may suggest fat-dissolving injections instead or as well.
How long until I see my face slimmer?
Most people notice a change from about 2 to 4 weeks after jaw Botox, with the full effect at around 6 to 8 weeks. The muscle shrinks gradually, so the result looks natural.
How long do the results last?
Jaw Botox usually lasts around 4 to 6 months. With regular treatment, many people find the muscle stays smaller and they need top-ups less often. Results vary with muscle strength and habits like clenching.
Is there downtime?
Very little. You may see small injection marks for a few hours and occasionally a little bruising. Most people go straight back to their day. Avoid massaging the area and chewing very hard food for a few days.
Will chewing feel different?
Some people notice their jaw tires more easily when chewing tough food for a few weeks. This is temporary and usually mild. Tell your doctor if you chew gum a lot or grind your teeth.
Can I get cheek slimming injections as a tourist?
Yes. The treatment takes only minutes and the slimming develops after you return home. Send your photos and travel dates and we will prepare a plan for your visit.
