Jaw botox in Korea: how 50 units differ by brand, and why slimming shows after you fly home
Masseter botox relaxes the chewing muscle at the angle of the jaw so the lower face looks narrower over several weeks. The usual dose is quoted in units, often 50 per session, and the brand moves the price more than the clinic does. Seoul price: $15–$105.

START WITH THE CONCERN
Which one is for what you actually want?
Most people arrive with a product name from social media. The doctors we work with start from the concern instead, and sometimes the answer is a different treatment, or none.

BEFORE AND AFTER
Real patients, with the clinic named
Photographs for this treatment are being added. Each will name the clinic, how long after treatment it was taken, and whether lighting matched.
RECOVERY AND YOUR FLIGHT
What the days after look like
- Day 0
Small bumps for a few hours. You can eat normally; avoid massaging the jaw.
- Week 1–2
Chewing hard food may feel a little weaker. That is the muscle relaxing.
- Week 4–6
The lower face looks slimmer. Judge it here, after you are home.
HONESTLY
When we would tell you not to book it
- You want a slimmer face in this trip's photos. It takes four to six weeks.
- Your face is wide from bone or fat rather than muscle.
- You are pregnant or breastfeeding.
- The quote does not say how many units or which brand.
HOW WE CHOOSE YOUR CLINIC
We vet the clinics first.
Then we match you to the doctor.
Seoul has hundreds of clinics selling Jaw (masseter) botox. We work with a short list that meets five conditions, and introduce you to the one or two doctors who fit your concern, your dates and your budget.
- 01
The consulting doctor is the treating doctor
We ask every clinic who actually holds the needle. A clinic that hands you to someone else after the consultation does not make our list.
- 02
Product, device and dose are named
“Premium booster” is not an answer. We only work with clinics that tell you the brand, the volume and the machine before you sit in the chair.
- 03
A written quote, per unit or per cc
So you can compare two clinics on the same scope rather than two totals that measure different things.
- 04
A doctor willing to say “not this”
We listen for it in consultations we sit in on. A clinic that agrees to everything is selling, not advising.
- 05
Someone to contact after you fly home
A named contact and channel for follow-up questions, agreed before treatment rather than discovered after.

QUESTIONS PEOPLE ACTUALLY ASK
Jaw (masseter) botox: the short answers
How much is jaw botox in Korea?
For 50 units in Seoul: about $15–$35 with a Korean toxin, $35–$70 with Coretox, around $70 with Xeomin and $70–$105 with Allergan Botox.
Is 50 units enough?
It is a common starting dose for both sides, but muscle size varies. Some people need more; the doctor decides after feeling the muscle. If more is suggested, ask for the new total in units and price.
Why is the cheapest price so low?
Usually a Korean toxin, a smaller dose, or a first-visit promotion. None of that is wrong, but compare the same brand and units.
How often should I repeat it?
Most people repeat every few months at first. Ask the doctor about spacing; very frequent high doses are not recommended.
