Quick answer:
Botox (botulinum toxin) in Seomyeon is most often used for forehead lines, frown lines between the brows and crow's feet. Effects typically begin within two to five days, reach their peak around two weeks, and usually last about three to four months. Duration varies with dose, muscle strength, metabolism and the product used.
What Botulinum Toxin Does
Botulinum toxin type A temporarily blocks the signal from nerves to muscles. When injected in small, precise doses, it relaxes targeted muscles so that the skin above them creases less with expression. It does not fill hollows or remove existing deep folds, which is why it is mainly used for dynamic wrinkles, the lines that appear when you move your face.
"Botox" is a brand name owned by Allergan, but in Korea people often use it for any botulinum toxin. Korea has several domestically manufactured products approved by the Ministry of Food and Drug Safety (MFDS), such as Botulax, Nabota, Meditoxin and Coretox, alongside imported brands such as Botox, Xeomin and Dysport. Products differ in formulation and dosing units, so units from one brand are not directly interchangeable with another. Ask which product is being used and see the vial if you wish.
Common Treatment Areas
Upper face
- Forehead lines:
horizontal lines from raising the brows. Doses are kept conservative to avoid a heavy or dropped brow.
- Glabellar (frown) lines:
the "11" lines between the eyebrows, one of the most studied indications.
- Crow's feet:
fine lines at the outer corners of the eyes when smiling.
Other areas often requested
- Bunny lines:
creases on the sides of the nose.
- Chin dimpling:
an orange-peel texture from an overactive chin muscle.
- Gummy smile:
to reduce upper lip elevation in selected cases.
- Neck bands and jawline:
sometimes used to soften platysmal bands.
- Masseter and shoulders:
for facial slimming and trapezius contour, covered in separate guides.
Some of these uses are off-label, meaning they fall outside the officially approved indications. That is common in aesthetic practice, but you should know when it applies and why the doctor recommends it.
Onset and Duration
- Days 2 to 5:
early softening of movement begins for most people.
- Around day 14:
the effect usually reaches its peak. This is a sensible time for a review if anything looks uneven.
- Three to four months:
typical duration for facial expression lines, with gradual return of movement.
Duration can be shorter in people with strong muscles, high metabolism or very active expressions, and with lower doses. Some people find results last longer after repeated treatments, though this is not guaranteed. Rarely, the body develops antibodies that reduce the effect; using the lowest effective dose and avoiding very frequent top-ups are often recommended to lower this risk.
What Happens at the Appointment
A consultation should include a look at your expressions, brow position and facial symmetry. The doctor marks injection points, cleans the skin and uses a fine needle. Numbing cream or ice may be used, though many people find the injections tolerable without it. The process often takes only ten to fifteen minutes. Because Seomyeon clinics cluster within walking distance of the station and the department store area, many visitors fit an appointment into a shopping afternoon.
Aftercare
- Stay upright for a few hours and avoid pressing or massaging the treated area that day.
- Skip intense exercise, saunas and jjimjilbang for the rest of the day, or as your doctor advises.
- Avoid alcohol on the day if you bruise easily.
- Do not book a facial massage or tight-fitting treatment over the area immediately afterward.
Side Effects and Risks
- Small bruises, redness or swelling at injection points
- Mild headache for a day or two
- Temporary asymmetry that may need a small adjustment
- Brow or eyelid drooping (ptosis), uncommon and usually temporary over weeks
- Rarely, allergic reactions or spread of effect beyond the intended muscles
Seek urgent medical help, or call 119 in Korea, if you develop difficulty swallowing, speaking or breathing after treatment.
Who Should Not Have It
- People who are pregnant or breastfeeding
- Those with neuromuscular disorders such as myasthenia gravis
- Anyone with an allergy to any product component
- People with infection or inflammation at the injection site
- Those taking certain medications, such as some antibiotics that affect nerve signaling, without medical advice
Understanding the Cost
Price depends mainly on the product brand, the number of units, the number of areas, and whether a follow-up adjustment is included. Domestic Korean toxins are often priced differently from imported brands. Ask for a quote that lists brand, units per area and VAT so you can compare fairly.
Frequently Asked Questions
When should I get botox before an event?
Ideally two to three weeks before, so the effect peaks and any bruising or asymmetry can be corrected in time.
Is Korean botulinum toxin as effective as imported brands?
MFDS-approved Korean products are widely used and studied, but brands differ in formulation and dosing. Results depend heavily on dose and technique.
Can I fly right after botox?
Generally yes. Flying is not thought to affect results, but plan a review around day 14 if possible, by photo if you have already left Busan.
Does botox remove deep static wrinkles?
It can soften them, but lines visible at rest may need additional treatments such as fillers or skin boosters.
Key Takeaways
- Botulinum toxin relaxes muscles to soften expression lines.
- Onset is usually two to five days, peak around two weeks, and duration about three to four months.
