Botulinum toxin softens dynamic wrinkles in the 3 upper-face zones most patients ask about: frown lines, forehead lines, and crow’s feet, with effect building over about 3 to 7 days.
Wrinkle treatment with botulinum toxin relaxes the small facial muscles that create dynamic lines, so frown lines, forehead lines, and crow’s feet soften. At our Incheon Airport (Yeongjongdo) location, Dr. Sunbeen Kim tailors the dose to your movement pattern, with results building over days and typically lasting about 3 to 4 months.

Wrinkle treatment with botulinum toxin is a non-surgical injection that temporarily relaxes the small muscles responsible for dynamic wrinkles, the lines that appear when you frown, raise your eyebrows, or smile. By easing that repeated muscle pull, the overlying skin creases less, so expression lines look softer and smoother over the following days.
It works best on dynamic (movement-related) lines rather than deep static folds that are present even at rest. The most commonly requested areas are the glabella (frown lines between the brows), horizontal forehead lines, and crow’s feet at the outer eyes. Because the effect is temporary and the muscle gradually recovers, the treatment is repeated as results wear off, usually every few months.
At Reberry Clinic, wrinkle treatment is consultation-led. For international patients passing through or staying near Incheon Airport, our Incheon Airport (Yeongjongdo) location offers assessment and treatment in English, with Dr. Sunbeen Kim, Medical Director, matching the dose and injection points to how your face actually moves.
Botulinum toxin type A is a purified neuromodulator that works at the junction between nerve and muscle. When injected in tiny, precise amounts into a target muscle, it temporarily blocks the release of acetylcholine, the chemical signal that tells the muscle to contract. With the signal reduced, the muscle relaxes and pulls on the skin less, so the dynamic crease it was forming gradually softens over roughly 3 to 7 days. The effect is localised to the injected muscles, which is why accurate placement matters: the goal is to relax the lines you want to soften while preserving natural expression. Over about 3 to 4 months the nerve endings regenerate, muscle activity returns, and the lines reappear, which is why the treatment is repeated. Dose is measured in units and matched to each muscle’s strength, so a strong frown muscle needs more than a delicate area near the eyes. This is a neuromodulator, not a filler; it does not add volume, so it is combined with other treatments when volume loss also contributes to a line.

Dr. Sunbeen Kim watches how you frown, raise your brows, and smile to map which of the 3 upper-face zones drive your lines.
Botulinum toxin is measured in units and matched to each muscle, so a strong frown muscle receives more than the delicate area around the eyes.
Using a fine needle, several small injections of a few units each are placed into the target muscles, usually within about 10 to 15 minutes.
The muscle signal is gradually blocked, so lines soften over about 3 to 7 days, with the full effect visible around 2 weeks.
Results typically last about 3 to 4 months; a review lets the dose be fine-tuned before your next session.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
Dr. Sunbeen Kim assesses how your face moves and which lines are dynamic, then explains the plan and expected results in English.
The session usually takes about 10 to 15 minutes; several small injections are placed with a fine needle after cleansing the area.
You can return to most normal activities immediately, with only minor pinpoint redness that settles within a few hours.
Lines soften over about 3 to 7 days, with the full effect visible around 2 weeks; a review can fine-tune the dose.
Results generally last about 3 to 4 months; avoid rubbing the area and heavy exercise for the rest of the treatment day.
It is a non-surgical injection that relaxes the small muscles creating dynamic wrinkles, so frown lines, forehead lines, and crow’s feet soften over about 3 to 7 days. It targets movement-related lines rather than deep static folds. You can read more on our botulinum toxin page before booking a consultation.
Dynamic wrinkles respond best, meaning lines that appear with movement such as frowning, raising the brows, or smiling. The most requested zones are frown lines, forehead lines, and crow’s feet. Our botulinum toxin assessment identifies which lines are dynamic before any treatment is planned.
Discomfort is usually minimal because very fine needles and tiny volumes are used, and each injection takes only a moment. Most patients describe a quick pinch or sting. A cool pack or topical numbing can be applied if you are sensitive. The whole session typically lasts about 10 to 15 minutes.
Downtime is minimal, so most people return to normal activities right away. You may notice tiny pinpoint redness or slight bumps that settle within a few hours. Avoid rubbing the area, lying flat, and heavy exercise for the rest of the day. This low recovery suits travellers on tight schedules.
Lines start softening over about 3 to 7 days, with the full effect visible around 2 weeks as the muscle relaxes. Results are gradual rather than instant, which keeps the look natural. If any area needs adjustment, a review lets Dr. Sunbeen Kim fine-tune the dose.
Results typically last about 3 to 4 months before muscle movement gradually returns and lines reappear. Longevity varies with muscle strength, dose, and area treated. Because the effect is temporary, the treatment is repeated to maintain smoothness rather than being a one-time fix.
It depends on how many zones you treat and how strong those muscles are, since dose is measured in units per muscle. A single upper-face session is common, then repeated every few months. Dr. Sunbeen Kim confirms the exact plan and units after assessing your movement at consultation.
Yes, when dosed carefully the aim is softer lines while preserving natural expression, not a frozen look. The dose is matched to each muscle so movement is reduced, not eliminated. Starting conservatively and reviewing after 2 weeks helps achieve a balanced, natural result you are comfortable with.
Yes, it is often combined with treatments that address different concerns, such as fillers for static folds or a thread lift for laxity. Because botulinum toxin does not add volume, combining it can give a more complete result and target several signs of ageing at once.
Common effects are mild and temporary, such as pinpoint redness, slight swelling, or occasional bruising at injection sites. Less commonly, temporary heaviness or asymmetry can occur and usually resolves as the effect settles. A careful assessment reduces risk, and your doctor reviews your history and medications first.
Botulinum toxin relaxes muscles to soften movement lines, while fillers add volume to fill static folds at rest, so they solve different problems. Many patients use both for a complete plan. You can compare volume-based options on our injectable fillers page to see which suits your lines.
Botulinum toxin for wrinkles is widely performed and considered to have a well-established safety profile when administered by a qualified doctor after review. Effects are temporary, and dose is tailored to you. Disclosing your medical history and any medications lets Dr. Sunbeen Kim screen for contraindications before treatment.
It is generally avoided during pregnancy or breastfeeding, with certain neuromuscular conditions, or if you have a known allergy to the product. Active skin infection at the site also delays treatment. Share your full history at consultation so your doctor can confirm whether wrinkle treatment is appropriate for you.
For the rest of the treatment day, avoid rubbing or massaging the area, strenuous exercise, saunas, and lying flat for a few hours. These steps help keep the product in the intended muscles. Gentle skin care and sunscreen support overall skin health between sessions.
You can be seen at our Incheon Airport (Yeongjongdo) location, close to ICN, which suits transit and short-stay travellers. Dr. Sunbeen Kim provides assessment and treatment in English. Reberry Clinic also has Seoul locations in Gangnam and Myeongdong if those fit your itinerary better.
Often yes, because the session takes about 10 to 15 minutes with little to no downtime, making it feasible near Incheon Airport during a longer stopover. Allow time for a consultation first. Our English-speaking team can help you plan timing around your flight so you are not rushed.
Yes, flying shortly after wrinkle treatment is generally fine since it is non-surgical with minimal downtime. Simply avoid rubbing the area and stay upright for a few hours as advised. If you also had other procedures the same day, Dr. Sunbeen Kim will give tailored travel and aftercare guidance.
Many international patients time repeat sessions around 3 to 4 months apart with return trips through Incheon Airport. Between visits you can maintain results at home with good skin care. Your treatment notes are kept on file so your plan stays consistent across visits.
