Jaw Slimming Botox in Seoul

How it works

The masseter is a chewing muscle that can enlarge with genetics or habitual clenching. Botulinum toxin reduces its activity, so the muscle gradually shrinks from disuse, giving a slimmer lower face. Dose and placement depend on muscle size, which the dermatologist assesses by palpation while you clench.

Who it's for

It is generally suited to people whose wide lower face is mainly due to large masseter muscles, and to some people with jaw clenching. A wide jaw due to bone structure, fat or sagging responds less, and other options may be discussed.

What to expect at The Heal Sinsa

Every visit to The Heal Dermatology Sinsa Main Branch, on the 7th floor of Sinsa Square near Sinsa Station, starts with a 1:1 consultation with a Korean board-certified dermatologist and imaging-based skin analysis. Your doctor checks whether Botox for Jaw Slimming actually suits your concern, explains alternatives honestly, and chooses conservative settings. Treatment is done in a private single room, and English or Traditional Chinese support is available on request. Before your visit, note your current medicines, skincare products, allergies and previous procedures so the doctor can plan safely. Pricing is confirmed after consultation; see pricing and payment.

Risks & who should avoid

If you notice increasing pain, spreading redness, blistering, discharge or fever after treatment, contact the clinic promptly and read what to do if complications occur.

Planning around your trip to Seoul

Jaw Botox needs no downtime, so it can fit into any stay, but the slimming effect appears only weeks later, usually after you return home. Read treatment before a flight and how many days to plan, and visit international patients or getting here before you book.

When will I see results from jaw Botox?

Muscle relaxation starts within days, but visible slimming happens gradually over about four to eight weeks as the muscle reduces in size. Photos taken before treatment help you compare the change accurately.

Does jaw Botox affect chewing?

Some people notice tiredness or mild weakness when chewing tough or chewy foods for a few weeks. Normal eating is usually unaffected, and the sensation typically resolves within a few weeks as you adapt.

How often should jaw Botox be repeated?

Many people repeat treatment about every four to six months initially. With regular treatment, some find intervals can gradually be extended. Your dermatologist adjusts dose to avoid over-thinning the muscle.
