Botulinum toxin type A relaxes targeted muscles to soften dynamic wrinkles, with results that typically last 3 to 4 months.
Botox in Seoul uses small injections of botulinum toxin type A to relax overactive facial muscles, softening dynamic wrinkles such as frown lines, forehead lines, and crow’s feet. The treatment takes about 10 to 15 minutes, results emerge within 3 to 7 days, and effects usually last 3 to 4 months across our three Seoul-area locations.

Botox is the common name for botulinum toxin type A, a purified neuromodulator injected in small doses to relax specific muscles. When a muscle moves less, the skin above it folds less, so dynamic wrinkles, the lines that form when you frown, smile, or raise your brows, soften. It is one of the most studied aesthetic injectables worldwide.
At Reberry Clinic, botox is consultation-led. The clinic’s doctors assess your muscle strength, facial balance, and the pattern of your lines before deciding where to inject and how much to use. Beyond wrinkles, botulinum toxin type A is also used to slim an overactive jaw (masseter), reduce a gummy smile, and ease excessive sweating.
Careful, conservative dosing keeps a natural look while preserving expression. International patients are supported in English across our three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport), so a consultation, treatment, and follow-up can be planned around a short trip.

Botulinum toxin type A is a neuromodulator that temporarily blocks the release of acetylcholine at the neuromuscular junction, the chemical signal that tells a muscle to contract. When precisely placed micro-doses are injected into a target muscle, that muscle relaxes, so the overlying skin creases less when you make expressions. The effect is gradual and reversible: over about 3 to 4 months, nerve terminals form new connections, muscle movement returns, and the treatment wears off. This is why botox is a maintenance treatment repeated periodically rather than a one-time procedure, and why dosing is tailored to each muscle’s strength.

The doctor studies your muscle movement and facial balance to plan placement, often across 4 to 20 injection points depending on the areas treated.
Tiny amounts of botulinum toxin type A are injected into the target muscles over about 10 to 15 minutes.
The toxin blocks acetylcholine release, reducing muscle contraction within 3 to 7 days.
As the muscle relaxes, dynamic lines soften, with full effect by around 2 weeks.
Movement returns over 3 to 4 months as nerve signalling recovers, so maintenance sessions sustain results.

The clinic’s doctors assess your muscle movement, facial balance, and goals, planning the areas, dose, and placement in English.
The injections take about 10 to 15 minutes; optional numbing cream or ice keeps the visit comfortable.
You can usually return to normal activities right away, avoiding rubbing the treated area for a few hours.
Wrinkles begin softening in 3 to 7 days, with the full effect at around 2 weeks.
Results last about 3 to 4 months; repeat sessions maintain a smooth, natural look.



Botox is the common name for botulinum toxin type A, a purified neuromodulator injected to relax overactive muscles and soften dynamic wrinkles such as frown and forehead lines. By reducing muscle movement, the skin creases less. Results appear within 3 to 7 days and typically last 3 to 4 months.
Botox commonly treats frown lines, forehead lines, and crow’s feet, and can slim an overactive jaw (masseter) or ease excessive underarm sweating. The plan is tailored to your goals at a consultation. You can review the full scope on our botox injection page before your visit.
Botox usually lasts about 3 to 4 months, after which muscle movement gradually returns and lines reappear. Larger or stronger muscles, such as the masseter, can sometimes hold effect a little longer. Most patients schedule maintenance three to four times a year to keep results consistent over time.
You will typically notice softening within 3 to 7 days, with the full effect developing by around 2 weeks as the muscle fully relaxes. Lines that move with expression respond first. Deeper lines present at rest may need a couple of sessions to improve gradually over several months.
Discomfort is minimal, described as brief pinprick sensations during the small injections. The needles are very fine, and ice or topical numbing can be used for sensitive patients. Most treatments take about 10 to 15 minutes, and any stinging fades almost immediately after each injection is given.
Downtime is minimal, and most patients return to daily activities right away. You may see tiny red marks or, rarely, a small bruise that settles within a few days. Avoid rubbing the area, lying flat, or vigorous exercise for several hours so the product settles where intended by your doctor.
Not when dosed conservatively. The aim is natural softening that still allows expression, so your face does not look stiff or unnatural. The clinic’s doctors tailor the dose to each muscle’s strength. You can read more about balanced injectable planning on our botox injection page.
Adults with dynamic wrinkles that appear on movement, or an overactive jaw muscle, are typical candidates. A consultation confirms suitability, since some medical conditions and medications need assessment first. To explore volume-based alternatives, see our injectable fillers page for static lines.
Botox relaxes muscles to soften dynamic lines, while filler adds volume to fill deep static creases and restore contour. They solve different problems and are often combined for balance. Learn how volume restoration works on our injectable fillers page, which complements muscle-relaxing treatment.
Yes, botox pairs well with hyaluronic acid filler for deep static lines and with energy-based skin tightening for texture and laxity. Your doctor sequences these safely within one plan. To understand non-injectable lifting options, see our Thermage FLX page for collagen-based tightening.
Masseter botox relaxes an overactive chewing muscle to create a slimmer, softer jawline over several weeks, and it can also ease jaw clenching. Because the muscle is large, effects often last toward the longer end of the range. Your doctor assesses muscle bulk and dose during your consultation before treatment.
Common effects are brief redness, tiny bruises, or mild tenderness that resolve within days. Less commonly, temporary asymmetry or a heavy feeling can occur, usually settling as the product balances. Serious reactions are rare with proper technique. Share your full medical history so your doctor can reduce any risk beforehand.
Botulinum toxin type A has a long, well-documented safety record for cosmetic use when administered by trained doctors at appropriate doses. Effects are temporary and reversible as the body restores nerve signalling over months. Choosing an experienced clinic and honest dosing matters far more than chasing the strongest possible result.
Aftercare is simple: stay upright for about 4 hours, avoid rubbing or massaging treated areas, and skip strenuous exercise, saunas, and alcohol that day. Pairing with a gentle skin care routine supports your skin. Your doctor provides written guidance to follow once you leave the clinic.
Botox needs very little time, so even a 1 to 2 day visit works for consultation and treatment. Because there is minimal downtime, you can sightsee the same day. Our English-speaking team helps schedule the appointment so it fits neatly into a short trip to Seoul without disruption.
Yes, you can fly the same day, since the treatment is quick and non-invasive. Try to stay upright during the first few hours rather than reclining immediately, and avoid rubbing the area. Cabin pressure does not affect the result, so air travel after botox is generally not a concern.
International patients can have remote check-ins in English about two weeks after treatment to confirm the result, and plan repeat sessions around future trips. You can also arrange complementary care such as skin care when you return. Your dosing notes are kept on file for consistency between visits.
