Botulinum toxin type A relaxes the orbicularis oculi muscle to soften the fan-shaped smile lines beside the eyes, with results that typically last 3 to 4 months.
Crow’s feet botox in Seoul uses small injections of botulinum toxin type A to relax the orbicularis oculi muscle, softening the fan-shaped lines beside your eyes when you smile or squint. 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.

Crow’s feet botox is the use of botulinum toxin type A, a purified neuromodulator, to relax the outer part of the orbicularis oculi, the circular muscle around the eye that creates the fan-shaped lines, also called smile lines or lateral canthal lines, when you smile or squint. By gently reducing this movement, the skin beside the eyes creases less, so dynamic lines soften and finer static lines may improve over time.
At Reberry Clinic, treatment is consultation-led. The clinic’s doctors assess your smile pattern, the spread of your lines, and the strength of the muscle before deciding on placement and dose, usually 2 to 4 injection points on each side. Careful, superficial dosing keeps a natural look and protects nearby muscles that shape the cheek and smile.
The eye area is delicate, so placement matters: injections sit a safe distance from the eye socket rim to avoid affecting eyelid or cheek movement. Crow’s feet treatment is often combined with forehead and glabella treatment for a balanced upper face. International patients are supported in English across our three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport).

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 small, superficial doses are injected into the outer fibres of the orbicularis oculi, that part of the muscle relaxes, so the skin beside the eye folds less when you smile or squint. The effect is gradual and reversible: as nerve terminals form new connections over roughly 3 to 4 months, muscle movement returns and the treatment wears off, which is why maintenance sessions are needed.

The doctor studies your smile and squint to plan placement across about 2 to 4 points on each side.
Tiny, superficial amounts of botulinum toxin type A are injected into the outer orbicularis oculi over about 10 to 15 minutes.
The toxin blocks acetylcholine release, reducing muscle contraction within 3 to 7 days.
As the muscle relaxes, the smile 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.

Crow’s feet botox is the injection of botulinum toxin type A into the outer orbicularis oculi muscle to soften the fan-shaped lines beside the eyes that appear when you smile or squint. By relaxing the muscle, the skin creases less. Results appear within 3 to 7 days and typically last 3 to 4 months before a repeat session.
Crow’s feet botox usually lasts about 3 to 4 months, after which muscle movement gradually returns and the smile lines reappear. Because the eye muscle is active, results can fade slightly sooner for some people; dosing is individualised on our botox injection page. Most patients refresh three to four times a year.
You will typically notice softening within 3 to 7 days, with the full effect developing by around 2 weeks as the muscle relaxes. Lines that fan out when you smile respond first. Finer static lines present at rest may improve more gradually and can benefit from a complementary treatment over time.
Discomfort is minimal, described as brief pinprick sensations during the 2 to 4 small injections on each side. The needles are very fine, and ice or topical numbing can be used for sensitive patients. The whole process takes about 10 to 15 minutes, and any stinging fades almost immediately after each injection around the eye.
Downtime is minimal, and most patients return to daily activities right away. Because the skin around the eyes is thin, a small bruise is a little more common here but settles within a few days. Avoid rubbing the area, lying flat, or vigorous exercise for several hours so the product settles where intended.
Not when dosed conservatively and placed correctly. The doctor keeps injections superficial and a safe distance from the cheek muscles, so your smile stays natural while the outer lines soften. The clinic’s doctors tailor the dose to your anatomy. You can read about injectable balance on our botox injection page.
With correct, superficial placement it should not. Injecting too low could weaken the cheek lift, so the doctor maps a safe zone above the cheekbone before treating. This is why an experienced clinic matters for the eye area. Your doctor explains the placement plan during your consultation before any injections are given.
Adults with dynamic smile lines that fan out beside the eyes are ideal candidates. Those with significant under-eye laxity or hollowing may need a combined plan rather than toxin alone. A consultation confirms suitability. Explore related options on our injectable fillers page.
Crow’s feet dosing is individualised, often a small number of units spread across 2 to 4 points per side, balanced with any forehead or glabella treatment as shown on our botox injection page. Your doctor sets a conservative dose to keep the smile natural.
Yes, it pairs well with forehead and glabella botox for a balanced upper face, and with energy-based tightening for crepey skin. Your doctor sequences these safely in one plan. To understand volume options around the eyes, see our injectable fillers page for how fillers differ from muscle relaxation.
Common effects are brief redness, small bruises, or mild tenderness that resolve within days. Less commonly, temporary asymmetry or a slightly altered smile can occur if placement is too low, usually settling as the product wears off. Serious reactions are rare with proper technique. Share your full medical history beforehand.
Botulinum toxin type A has a long, well-documented record for treating crow’s feet when administered by trained doctors using superficial, well-mapped placement. Effects are temporary and reversible as nerve signalling recovers 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 around the eyes, and skip strenuous exercise, saunas, and alcohol that day. Pairing with a gentle skin care routine supports the delicate eye area. Your doctor provides written guidance to follow once you leave.
Crow’s feet 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.
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 around the eyes. Cabin pressure does not affect the result, so air travel after crow’s feet 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.
