Masseter Botox at the jaw angle takes two to four weeks to show, while forehead and eye lines respond in three to seven days, and that timing shapes how you plan Botox in Korea around a short trip. At ENTER Plastic Surgery in Seoul, every area on the price list comes in three tiers: Korean botulinum toxin, Xeomin and BOTOX by Allergan.
How to choose
Before the needle: what to check at a Botox clinic
A Botox appointment in Seoul is short and easy to book, which is the reason to ask a few questions before you sit down. Each of these can be answered by message ahead of the visit.
The product named on your quote
Botulinum toxin is sold under several brands. Ask which one will be used for each area and whether you can see the label before the injection.
Pricing by area or by units
At ENTER Plastic Surgery, wrinkle areas, the jaw and the gummy smile are priced per area, while the trapezius and calves are priced per 100 units. Ask how the dose for your area is set.
The injector
Ask for the name and specialty of the physician who will give the injections.
A plan based on anatomy
A wide lower face can come from the masseter muscle, the salivary gland, fat or bone. Toxin acts on muscle and gland, so ask what the clinic sees in your photos before agreeing to a jaw plan.
Timing against your trip
Lines soften after three to seven days; the jaw and calves take two to four weeks. If you leave Korea within days, the jaw change will appear at home.
How long it lasts and when to repeat
The clinic's guidance is three to four months for wrinkle areas, four to six months for the jaw, trapezius and calves, and about six months for the chin, with repeat sessions three to six months apart.
Aftercare in writing
Stay upright for three to four hours, wash gently that day and leave makeup until the next. Bruising, swelling, small bumps and tingling for two to three days are expected.
Clinic types
Best Botox in Seoul: Where It Is Offered and What to Ask
Botox is sold in many kinds of settings in Seoul, and the same injection can be a very different visit from one to the next. The table lists the common ones and the question that tells you how each one works.
| Setting | What a visit looks like | What to ask |
|---|---|---|
| Plastic surgery clinic with an injectables menu | Botox offered next to surgery and lifting | Which physician injects, and which brands are stocked? |
| Skin and laser clinic | Botox with lasers and skin boosters | Does the brand on the receipt match the brand on the price list? |
| High-volume injection clinic | Short visits at set prices | How is the dose chosen for my muscle? |
| Agency or beauty tour package | Botox bundled with other services | Which clinic injects, and what is the itemized price? |
Any of these can give a sound treatment. What separates them for you is whether the brand, the dose, the injector and the timing are stated before the needle goes in.
Prices
Botox prices at ENTER Plastic Surgery by area and brand
Each area appears three times on the price list, once for each toxin: Korean botulinum toxin, Xeomin and BOTOX by Allergan. The cards show three of the areas in all three tiers; gummy smile, jawline, temple, salivary gland and scalp are priced in the same three-tier way. Amounts are before tax, with 10% VAT added at payment.
The brands are different products from different makers. The price list does not rank them, and which one to use is a choice you make with the physician.

Products used
Botulinum toxin products on the ENTER Plastic Surgery menu
Two of the three tiers are named imported products: BOTOX Cosmetic (onabotulinumtoxinA) from Allergan and XEOMIN from Merz. The third tier is listed as Korean botulinum toxin, a product of a Korean manufacturer; the price list names it by category, so this page does as well.
Units of one toxin brand do not convert one-to-one into units of another, so the dose is set for the product actually being used.
Evidence
What the research on jaw and shoulder Botox shows
The evidence for masseter Botox has grown over the past decade. When a Cochrane review looked in 2013, it found no randomized trials of botulinum toxin for benign masseter enlargement, so there was no high-level evidence either way (Fedorowicz, 2013). A 2026 meta-analysis of five randomized trials with 536 participants then found that toxin reduced jaw prominence and muscle thickness and improved satisfaction compared with placebo in the short term. The ideal dose and protocol remain unsettled, and longer trials are still needed (Machado, 2026).
For the shoulders, a study of ultrasound-guided injection at five points suggested that toxin may help with trapezius enlargement (Chen, 2021). It was a single study with low certainty, and it does not describe the clinic's own injection method.
Side effects to know by name:
- Bruising, swelling or small bumps at the injection points
- An uneven effect between the two sides
- Tiredness when chewing after jaw injection
- A heavy brow or drooping lid after forehead or brow injection
- Weakness spreading beyond the treated muscle, which needs medical review
Timing
When Botox shows and how long it lasts, area by area
The figures below come from the clinic's own guidance. Results vary from person to person.
| Area | Effect starts | Effect lasts |
|---|---|---|
| Forehead, glabella, crow's feet, mouth corners, nose | About 3–7 days | About 3–4 months |
| Masseter (jaw angle) | About 2–4 weeks | About 4–6 months |
| Calves | About 2–4 weeks | About 4–6 months |
| Trapezius | Not given in the guidance | About 4–6 months |
| Chin (dimpled chin) | Not given in the guidance | About 6 months |
Injection takes about 10–15 minutes and needs no anesthesia. The clinic's guidance allows flying four hours after treatment, so Botox fits even a stopover day. If smoother lines are the goal, book early in the trip so the effect starts before you leave; the jaw, trapezius or calves will change after you are home. Repeat treatment is planned three to six months apart, which suits visitors who come back to Seoul a few times a year.

FAQ
Questions from people comparing Botox clinics in Korea
What should I look for in a Botox clinic in Korea?
Choose on clear answers about the product, the dose and the injector. Ask which brand is used for each area, whether the price is per area or per unit, who gives the injections, and when the effect should appear. Written answers make the visit easy to plan around your flights.
What is the difference between the three toxin tiers?
They are different products from different makers. BOTOX Cosmetic comes from Allergan and XEOMIN from Merz, and the third tier is a Korean botulinum toxin listed by category. The clinic's price list does not rank them, and the dose is set for whichever product is used.
Will my jaw look slimmer before I fly home?
Not if you leave within a week or two. Masseter Botox takes about two to four weeks to show, by the clinic's guidance, so the change will appear after you return. Lines on the forehead or around the eyes respond sooner, within about three to seven days.
Can I lie down on the plane after Botox?
Wait three to four hours before lying down. The clinic's guidance allows flying four hours after injection, so a short gap between the appointment and the airport covers both. Sitting in a plane seat counts as staying upright.
How long does Botox last in each area?
About three to four months for wrinkle areas, four to six months for the jaw, trapezius and calves, and about six months for the chin, by the clinic's guidance. Results vary between people, and repeat sessions are spaced three to six months apart.
Is the Botox price per area the final amount?
Not yet. The listed amount excludes VAT, which adds 10% at payment, and it is set per area, or per 100 units for the trapezius and calves; for example, 100 units of Korean toxin is ₩150,000 before VAT. Your quote shows how many areas or units your plan uses.
Can Botox slim a square jaw caused by bone?
No. Botulinum toxin relaxes muscle, so it changes the jaw angle when an enlarged masseter is the cause. Width that comes from bone or fat does not respond to it. Clenching your teeth during the examination shows how much of the width is muscle.
