Botox uses botulinum toxin type A to relax the muscles behind dynamic lines, softening frown, forehead, and crow’s-feet wrinkles for about 3 to 4 months.
Botox is a botulinum toxin type A injection that temporarily relaxes the muscles creating dynamic facial lines, softening frown lines, forehead lines, and crow’s feet over 3 to 14 days. The effect lasts about 3 to 4 months, so it is a maintenance treatment. Our Incheon Airport (Yeongjongdo) location offers doctor-led botox with English support.

Botox is a cosmetic injection of botulinum toxin type A, a purified neuromodulator that temporarily relaxes specific facial muscles. It is one of the most widely performed non-surgical aesthetic treatments worldwide. By calming the muscles that repeatedly crease the skin, botox softens dynamic wrinkles: the vertical frown lines between the brows, horizontal forehead lines, and crow’s feet at the outer eyes. Results build over 3 to 14 days rather than instantly.
It is important to understand what botox does and does not do. It works on dynamic lines driven by movement, not on deep static folds that stay visible when your face is at rest, which are usually better addressed with a hyaluronic acid filler or an energy treatment. Botox is also temporary: as the muscle gradually regains movement over about 3 to 4 months, lines return, so maintenance sessions keep results steady. Beyond wrinkles, botox is used for masseter (jaw) slimming and for excessive sweating.
At Reberry Clinic, botox is doctor-led and tailored to your muscles rather than delivered by a fixed recipe, which helps preserve natural expression. For international patients, our Incheon Airport (Yeongjongdo) location is a short transfer from the terminals, with Dr. Seongjun Cho, our Medical Director, and full English support, making it convenient for a stopover or on arrival. Cost is explained transparently at consultation.
Botox works by blocking the chemical signal, acetylcholine, that a nerve uses to tell a muscle to contract. When that signal is interrupted at the targeted point, the muscle relaxes, and the skin above it creases less, so dynamic wrinkles soften over about 3 to 14 days. A skilled injector maps the exact muscles driving your lines, such as the glabella for frown lines, the frontalis for forehead lines, and the orbicularis oculi for crow’s feet, then doses each point to relax the wrinkle while preserving natural movement. The effect is not permanent: nerve endings gradually form new connections and muscle activity returns over roughly 3 to 4 months, which is why botox is repeated as maintenance. Larger muscles like the masseter need higher unit counts than delicate eye-area muscles, so dosing is always individual. Because it addresses only movement-related lines, botox is frequently combined with a filler for deeper static folds, giving a more complete result than either treatment alone. Careful placement by an experienced doctor is what keeps expressions natural rather than frozen.

The doctor identifies which of the 3 common upper-face areas are dynamic and maps the muscles driving each line.
Units are tailored to each muscle’s strength, so 2 people treating the same area may receive different amounts.
Botox is placed at precise points with a fine needle, and the session usually takes about 10 to 15 minutes.
The treated muscle relaxes over 3 to 14 days, softening the overlying dynamic wrinkle gradually and naturally.
Because movement returns over about 3 to 4 months, repeat sessions keep lines soft over time.

The clinic’s doctors assess which lines are dynamic, map your muscles, and explain the plan and cost transparently in English.
After a short numbing or cooling step, the injection itself usually takes about 10 to 15 minutes.
Botox is not a one-off; softening builds over 3 to 14 days and is maintained with repeat sessions every few months.
Dynamic lines typically soften within about 2 weeks, and your doctor reviews the result before any top-up.
Because effects fade over roughly 3 to 4 months, maintenance keeps lines soft, and simple aftercare protects your result.
Botox is a botulinum toxin type A injection that relaxes the muscles creating dynamic facial lines, softening frown, forehead, and crow’s-feet wrinkles over 3 to 14 days. At our Incheon Airport location it is doctor-led and given in English. You can read more on our botox injection page.
Botox commonly treats dynamic upper-face lines: frown lines between the brows, horizontal forehead lines, and crow’s feet at the outer eyes. It is also used for masseter jaw slimming and for excessive underarm sweating. Your doctor confirms which areas suit your goals at consultation, since not every line responds to toxin alone.
No, botox works on dynamic lines caused by muscle movement, not on deep static folds visible when your face is at rest. Those usually need a hyaluronic acid injectable filler for volume. A good clinic assesses your line type first, so you get the right treatment rather than a default injection for everything.
Botox for facial lines typically lasts about 3 to 4 months before the muscle gradually regains movement and lines return. It is a maintenance treatment, not a one-time fix, so repeat sessions keep results steady. Jaw or masseter botox for slimming can last a little longer as the muscle reduces over time.
Most people notice dynamic lines softening within about 3 to 14 days, with the full effect around two weeks. Because it is gradual rather than instant, your doctor reviews the result before adding any top-up. This staged approach avoids overtreatment and helps keep your expressions looking natural.
Botox uses a very fine needle, so most patients feel only a brief pinch at each point. Numbing cream or cooling can be applied for comfort, and the whole session usually takes about 10 to 15 minutes. Discomfort is short-lived, and careful technique from a skilled injector keeps it minimal.
Downtime is usually minimal, so most people return to normal activities the same day. Temporary redness or small bumps at the injection points fade within hours. Your doctor advises avoiding heavy exercise, saunas, and lying flat for a short period. You can review the approach on our botox injection page.
Common side effects are mild and temporary, such as slight bruising, redness, or a brief headache. Rarely, uneven results or temporary eyelid or brow droop can occur, which is why injector skill matters. A meta-analysis of nearly 9,700 patients reported a favourable safety profile, with most effects resolving on their own over days.
Not when dosing is tailored to your muscles rather than applied by a fixed recipe. A skilled doctor relaxes the lines while preserving natural movement and expression. Choosing a doctor-led clinic that assesses your face individually is the best way to avoid an overdone look, rather than accepting one standard dose for everyone.
Yes, botox and filler are often combined because they solve different problems: botox relaxes dynamic muscles while filler restores volume in static folds. Sequencing them thoughtfully gives a more complete, natural result. Your doctor recommends a filler only when your static lines genuinely call for it.
Yes, botox in the masseter muscle can gradually slim a strong or square jawline by reducing muscle bulk over several weeks. It uses more units than facial-line treatment because the masseter is large. Results build over time and are maintained with repeat sessions, which your doctor plans based on your muscle strength.
Most healthy adults with dynamic frown, forehead, or crow’s-feet lines are suitable candidates. A consultation confirms your line type and rules out contraindications like pregnancy or certain neuromuscular conditions. If your concern is deep static folds or general laxity, your doctor may suggest a filler or an energy treatment instead.
Botox cost depends on how many areas you treat, the units your muscles need, and whether filler is added, so it is confirmed at consultation rather than fixed. The clinic’s doctors explain it transparently in English. You can compare related options on our injection treatment page.
For a few hours, stay upright, avoid rubbing the treated area, and skip intense exercise, saunas, and alcohol that day. Good daily skincare and sun protection support overall skin quality between sessions. A consistent skin care routine complements your botox result and keeps skin looking healthy.
If your main concern is sagging or laxity rather than expression lines, an energy device may suit you better. Ultrasound or radiofrequency lifting such as Ultherapy Prime tightens deeper tissue. A good clinic identifies whether you have dynamic lines, laxity, or both, and may combine treatments for a fuller result.
A single botox session needs only a short visit, so even a stopover near Incheon Airport can cover a consultation and treatment in one trip. If you combine botox with filler, allow a little extra time for a review. Our English-speaking team helps coordinate timing around your flights.
Yes, flying within a day or so is generally fine after botox, which is convenient when treated near Incheon Airport before departure. Avoid rubbing the treated area and stay upright for a few hours before your flight. If you also had filler, your doctor gives specific aftercare advice for travelling comfortably.
