Botulinum toxin softens dynamic wrinkles for roughly 3 to 4 months, so choosing a clinic is about the doctor’s dosing judgment across the 3 upper-face zones, not a single price.
To choose a good wrinkle treatment clinic near Hongdae, look for a doctor-led consultation that maps your dynamic lines, individualised botulinum toxin dosing across forehead, frown, and crow’s feet, honest talk about the 3-to-4-month duration, and structured follow-up. For patients near Hongdae (Hongik Univ.) Station, care is provided across our Seoul locations, Gangnam and Myeongdong.

Wrinkle treatment with botulinum toxin looks simple from the outside, but the difference between a natural result and a frozen or uneven one comes down to the doctor’s judgment. A good clinic starts with an assessment of which lines are dynamic (formed by muscle movement, such as frown lines, forehead lines, and crow’s feet) versus static (etched into resting skin), because botulinum toxin softens the dynamic ones by relaxing the muscle, while deeper static lines may need a different or combined plan.
The second marker of quality is individualised dosing. Botulinum toxin type A is a neuromodulator, and how many units go into each of the roughly 3 upper-face zones must be tailored to your muscle strength, anatomy, and the look you want. Over-treating flattens expression; under-treating fades quickly. A doctor-led consultation, rather than a fixed menu, is the clearest sign a clinic is treating you as an individual.
At Reberry Clinic, wrinkle care is consultation-led and explained in English. For international patients near Hongdae (Hongik Univ.) Station, treatment is provided across our Seoul locations (Gangnam, Myeongdong), both easily reached from 홍대입구역, so you can plan a visit around your schedule in the city.
Dynamic wrinkles form because the same facial muscles contract thousands of times a day, folding the skin above them until lines set in. Botulinum toxin type A works at the neuromuscular junction: it temporarily blocks the nerve signal that tells the treated muscle to contract, so the muscle relaxes and the overlying skin creases less. Because the effect is targeted, a skilled doctor can soften a frown while leaving natural movement elsewhere. A good clinic uses this precisely, placing small, measured amounts into the frontalis for forehead lines, the glabellar complex for the 11-lines between the brows, and the orbicularis oculi for crow’s feet. Onset is gradual, usually beginning within 3 to 5 days and settling by about 2 weeks, and the effect typically lasts 3 to 4 months before the muscle gradually regains movement. The clinic’s doctors reassess at follow-up because dosing often refines over the first 1 or 2 sessions as they learn how your muscles respond.

A good clinic assesses your lines across the 3 upper-face zones and distinguishes dynamic from static wrinkles before quoting anything.
Units should be tailored to your muscle strength, not a flat number; expect the doctor to explain why each of the 3 areas gets a specific amount.
A trustworthy clinic tells you botulinum toxin lasts about 3 to 4 months and plans maintenance honestly, rather than implying it is permanent.
The plan should preserve some expression; ask how they avoid a frozen look, which usually means conservative dosing over 1 or 2 sessions.
Good clinics review you around 2 weeks after your first session to fine-tune, since dosing often refines over the first visit or two.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.





The clinic’s doctors assess which of your lines are dynamic across the 3 upper-face zones and explain a tailored, English-language plan.
A botulinum toxin session usually takes about 10 to 15 minutes, with fine injections placed into the mapped muscles.
Effects begin within 3 to 5 days and settle by around 2 weeks, when your result is at its clearest.
Softening typically lasts 3 to 4 months, after which movement gradually returns and maintenance is planned.
Avoid rubbing the area and lying flat for 4 hours; a follow-up around 2 weeks lets your doctor refine dosing.

Dynamic wrinkles form from muscle movement, such as frown lines, forehead lines, and crow’s feet, and respond well to botulinum toxin. Static lines stay visible at rest and may need filler or a combined plan. A consultation identifies which type you have before any treatment is chosen.
Botulinum toxin softening typically lasts about 3 to 4 months before muscle movement gradually returns. Duration varies with muscle strength, dose, and the area treated. Because it is maintained rather than permanent, a good clinic plans your maintenance schedule honestly at consultation instead of implying a one-time result.
Cost depends on how many areas are treated and the units your muscles need, so there is no single fixed figure. A frown-only plan differs from full upper-face treatment. The clinic’s doctors confirm your individualised cost at consultation. You can read more on our botox injection page.
Discomfort is usually minimal, described as a quick pinch, since fine needles are used and each injection takes seconds. Numbing cream or ice can be applied for sensitive patients. Most people return to normal activities immediately, though your doctor will give specific aftercare for the first few hours.
Units are tailored to your muscle strength and the areas treated, not a flat number, which is why individualised dosing marks a good clinic. Frown lines, forehead, and crow’s feet each need different amounts. Your doctor explains the plan at consultation and may refine it over the first 1 or 2 sessions.
A natural result is the goal, and conservative, well-placed dosing preserves some expression rather than freezing the face. A frozen look usually comes from over-treatment. This is why choosing a doctor who plans carefully across the 3 zones, and reviews you at follow-up, matters more than the lowest price.
Softening usually begins within 3 to 5 days and reaches its clearest look by about 2 weeks. Results are not instant because the toxin needs time to relax the muscle. Your doctor reviews you around the 2-week mark to check the effect and fine-tune dosing if needed.
Yes, botulinum toxin for dynamic lines is often combined with filler for static folds or with energy-based skin tightening for overall firmness, planned by your doctor. Combining addresses different wrinkle types together. You can explore related options such as injectable fillers at consultation.
Botulinum toxin type A is widely studied and generally well tolerated when a trained doctor doses and places it correctly. Korean and international trials report favourable safety profiles. Temporary effects like small bruises or mild heaviness can occur. A consultation reviews your history to confirm you are a suitable candidate first.
Most healthy adults with dynamic frown, forehead, or crow’s-feet lines are suitable candidates for botulinum toxin. Pregnancy, breastfeeding, and certain neuromuscular conditions are contraindications. A consultation reviews your health, medications, and goals so the doctor can confirm suitability and design an appropriate, natural-looking plan.
Avoid rubbing or massaging the treated area, strenuous exercise, and lying flat for about 4 hours so the toxin stays where placed. Skip saunas and heavy heat that day. These simple steps help results settle evenly, and your doctor gives you the full aftercare list before you leave.
Most people repeat botulinum toxin every 3 to 4 months as the effect fades, though intervals lengthen for some over time. Your doctor plans a schedule based on how your muscles regain movement, tracked on our botox injection page plan so maintenance stays natural rather than over-treated.
Treating one zone, such as the frown, can subtly change how nearby muscles pull, which is why doctors assess the forehead, glabella, and crow’s feet together. Balanced dosing across areas keeps the result harmonious. This whole-face planning is another reason a doctor-led clinic is worth choosing over a menu.
A single day is usually enough for a consultation and botulinum toxin session, since downtime is minimal. Many international patients treat wrinkles as part of a wider trip. Because full results appear by about 2 weeks, some plan a remote check-in after returning home, coordinated by our English-speaking team.
Yes, flying within a day is generally fine, as botulinum toxin injections are non-invasive with minimal downtime. Avoid rubbing the area and stay upright for a few hours before travel. Your doctor gives you aftercare guidance for the journey. You can also review our skin care tips for travel.
International patients can complete treatment in one visit and have a remote check-in in English around the 2-week mark to confirm results. Your treatment notes are kept on file for continuity on return trips. Between visits, a supportive skin care routine helps maintain overall skin quality.
