Botulinum toxin type A relaxes the nasalis muscle to soften the diagonal bunny lines beside the nose, with results that typically last 3 to 4 months.
Bunny lines botox in Seoul uses tiny injections of botulinum toxin type A to relax the nasalis muscle, softening the diagonal wrinkles that appear beside the nose when you smile or scrunch. The treatment takes about 5 to 10 minutes, results emerge within 3 to 7 days, and effects usually last 3 to 4 months.

Bunny lines are the short, diagonal wrinkles that fan out across the upper sides of the nose when you scrunch your nose, laugh, or smile broadly. They are created by the nasalis muscle, and like other dynamic lines they deepen with repeated movement over the years. Bunny lines botox uses botulinum toxin type A, a purified neuromodulator, to gently relax this muscle so the skin above it creases far less.
At Reberry Clinic, treatment is consultation-led. The clinic’s doctors assess how strongly your nasalis contracts, whether the lines are dynamic or already set at rest, and how the area interacts with nearby muscles before deciding on placement and dose. Only 2 to 4 small injection points are usually needed, with conservative dosing to keep your smile natural.
Bunny lines often become more visible after the glabella (frown lines between the brows) is treated, because the nasalis can compensate for the relaxed frown muscles. For this reason doctors frequently plan the two areas together. 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 a small, precisely placed dose is injected into the nasalis, that muscle relaxes, so the skin over the upper nose folds far less when you scrunch or smile. The effect is gradual and reversible: as nerve terminals form new connections over several months, muscle movement returns and the treatment wears off, which is why maintenance sessions are needed to keep bunny lines soft.

The doctor watches you scrunch and smile to map the nasalis and plan roughly 2 to 4 injection points.
Tiny amounts of botulinum toxin type A are placed into the nasalis muscle over about 5 to 10 minutes.
The toxin blocks acetylcholine release, reducing muscle contraction within 3 to 7 days.
As the nasalis relaxes, the diagonal 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.

You can usually return to normal activities right away, avoiding rubbing the area for a few hours.

Results last about 3 to 4 months; repeat sessions maintain a smooth, natural look.



Bunny lines are the diagonal wrinkles that appear on the upper sides of the nose when you scrunch your nose, laugh, or smile broadly. They are formed by the nasalis muscle. Bunny lines botox relaxes that muscle so the skin creases less, with results appearing within 3 to 7 days and lasting 3 to 4 months.
Bunny lines botox usually lasts about 3 to 4 months, after which the nasalis gradually regains movement and the lines reappear. Dosing is small and individualised, as explained on our botox injection page. Most patients schedule maintenance three to four times a year to stay smooth.
You will typically notice softening within 3 to 7 days, with the full effect developing by around 2 weeks as the nasalis fully relaxes. Lines that appear only when you scrunch or smile respond first. Because the dose is small, onset feels gradual and natural rather than abrupt or obvious to others.
Discomfort is minimal, described as brief pinprick sensations during the 2 to 4 tiny injections beside the nose. The needles are very fine, and ice or topical numbing can be used for sensitive patients. The whole process takes about 5 to 10 minutes, and any stinging fades almost immediately after each injection.
Downtime is minimal, and most patients return to daily activities right away. You may see tiny red marks or, rarely, a small bruise near the nose that 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. The aim is to soften the bunny lines while keeping your natural smile and expression intact. The clinic’s doctors place only small amounts into the nasalis. You can read about overall injectable balance on our botox injection page before your visit.
When the glabella frown muscles are relaxed, the nasalis can compensate and scrunch more, making bunny lines newly visible. This is common and easily addressed by treating the nasalis at the same time. Your doctor often plans both areas together for a balanced upper-face result during your consultation.
Adults with dynamic bunny lines that appear on smiling or scrunching are ideal candidates. A consultation confirms suitability, since asymmetric smile patterns need careful assessment to avoid affecting your expression. Explore related injectable options on our injectable fillers page.
Bunny lines need only a small dose, often a few units per side placed across 2 to 4 points, as individualised on our botox injection page. Clinical reviews describe roughly 2 to 5 units per side into the nasalis, but your doctor sets the exact dose for your anatomy.
Yes, it pairs well with glabella and crow’s feet treatment for a balanced upper face, and with hyaluronic acid filler for deep static lines. Your doctor sequences these safely in one plan. To understand volume-based options, see our injectable fillers page for how fillers differ from muscle relaxation.
Common effects are brief redness, tiny bruises, or mild tenderness beside the nose that resolve within days. Less commonly, slight changes to your smile can occur if the dose spreads, usually settling as the product balances. Serious reactions are rare with proper technique. Tell your doctor your full medical history 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, conservative dosing matters far more than chasing the strongest possible result.
Aftercare is simple: stay upright for about 4 hours, avoid rubbing or massaging the nose area, and skip strenuous exercise, saunas, and alcohol that day. Pairing with a gentle skin care routine supports the skin. Your doctor provides written guidance to follow once you leave.
Bunny lines 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 the area. Cabin pressure does not affect the result, so air travel after bunny lines 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.
