A few units of botulinum toxin type A relax the upper lip muscle so the lip rolls outward, with results that typically last 6 to 10 weeks.
A lip flip uses 2 to 6 units of botulinum toxin type A injected along the upper lip border to relax the orbicularis oris muscle, so the lip gently rolls outward and shows more pink. It adds no volume, takes about 5 to 10 minutes, shows in 3 to 7 days, and lasts 6 to 10 weeks.

A lip flip is a subtle injectable technique that uses very small amounts of botulinum toxin type A along the upper lip line to relax the orbicularis oris muscle. As the muscle eases, the upper lip rolls slightly upward and outward, revealing more of the pink lip and softening a thin or downturned upper lip. It is not a filler, so it adds no actual volume.
At Reberry Clinic, the procedure is consultation-led. The clinic’s doctors look at your lip shape, how much your upper lip rolls inward when you smile, and how much your teeth show, before choosing a conservative dose. Typically only 2 to 6 units are used, far less than a forehead or jaw treatment, which keeps speech and eating natural.
A lip flip suits people who want a soft, natural enhancement rather than the obvious plumping of hyaluronic acid filler. 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 acetylcholine release at the neuromuscular junction, the chemical signal that tells a muscle to contract. For a lip flip, 2 to 6 units are placed very superficially at the upper vermillion border, mainly at the cupid’s bow and corners. This eases the inward-pulling action of the orbicularis oris, so the upper lip relaxes and rolls outward, exposing a little more pink. Because the dose is tiny and placement is shallow, lip strength for speaking and drinking is largely preserved, and the effect reverses as nerve signalling recovers over weeks.

The doctor checks your lip roll, smile, and tooth show to plan placement across roughly 2 to 4 injection points.
Around 2 to 6 units of botulinum toxin type A are placed superficially along the upper lip border in about 5 to 10 minutes.
The toxin reduces orbicularis oris contraction, with the muscle starting to relax within 3 to 7 days.
The upper lip gently rolls outward, showing more pink, with full effect by around 10 to 14 days.
The flip softens over 6 to 10 weeks as nerve signalling recovers, so maintenance sessions sustain the look.

The clinic’s doctors assess your lip roll, smile, and goals, planning a conservative 2 to 6 unit dose in English.
The injections take about 5 to 10 minutes; ice or numbing keeps the sensitive lip area comfortable.
You can usually return to normal activities right away, avoiding straws, hot drinks, and lip pressure for a few hours.
The roll begins in 3 to 7 days, with the full effect at around 10 to 14 days.
The flip lasts about 6 to 10 weeks; repeat sessions maintain the subtle, natural look.
A lip flip uses a tiny dose of botulinum toxin type A, usually 2 to 6 units, along the upper lip border to relax the muscle so the lip rolls outward and shows more pink. It adds no volume. Results appear in 3 to 7 days and typically last 6 to 10 weeks before a repeat session.
A lip flip relaxes the upper lip muscle so it rolls outward, while filler adds physical gel volume into the lip. The flip is subtler and shorter-lasting, and the two are often combined. You can compare volume-based options on our injectable fillers page to decide what fits your goal.
A lip flip usually lasts about 6 to 10 weeks, shorter than most botox areas because the dose is small and the lip moves constantly. Dosing is individualised on our botox injection page. Most patients schedule maintenance every two to three months to keep the effect.
You will usually notice the upper lip rolling outward within 3 to 7 days, with the full effect by around 10 to 14 days as the muscle fully relaxes. The change is subtle by design, showing a little more pink lip rather than a dramatic increase in size, so give it the full two weeks.
Discomfort is minimal, described as brief pinpricks during 2 to 4 very superficial injections. The lip is sensitive, so ice or topical numbing is often used for comfort. The whole process takes about 5 to 10 minutes, and any stinging fades quickly. Most patients find it easily tolerable without much fuss.
Downtime is minimal, and most patients return to daily activities right away. You may notice tiny red marks or, rarely, a small bruise that settles within a few days. Avoid pressing the lips, using straws, and very hot drinks for several hours so the product settles where it was placed.
A lip flip is a microdose treatment, typically 2 to 6 units of botulinum toxin type A spread across the upper lip, as outlined on our botox injection page. The exact amount depends on your lip strength and goal, and your doctor sets it conservatively to keep speech natural.
When dosed conservatively, speech and eating stay largely normal. Because only 2 to 6 superficial units are used, lip strength is mostly preserved, though some people notice slight changes in pronouncing certain sounds or whistling for the first week. These ease as the dose balances, and your doctor adjusts future treatments accordingly.
Adults whose upper lip rolls inward or looks thin when smiling are ideal candidates, as are those wanting a natural lift without added volume. A consultation confirms suitability and the right approach. If you want more fullness, explore our injectable fillers page to weigh the options together.
Yes, a lip flip pairs very well with hyaluronic acid filler. The flip refines the shape and roll while filler adds volume, and many patients do both for a balanced result. Your doctor sequences them safely in one plan. See volume options on our injectable fillers page before deciding.
Common effects are brief redness, tiny bruises, or mild tenderness that resolve within days. Less commonly, temporary lip asymmetry, difficulty whistling, or a slightly weaker pucker can occur, usually settling as the dose balances over the first week or two. Serious reactions are rare with proper, superficial technique by a trained doctor.
Botulinum toxin type A has a long, well-documented safety record for facial use when administered by trained doctors at appropriate doses. For lips, conservative microdosing matters, since the area is mobile and sensitive. Effects are temporary and reverse as nerve signalling recovers over weeks, and an honest, careful plan is more important than a stronger effect.
Aftercare is simple: stay upright for a few hours, avoid pressing or massaging the lips, and skip straws, very hot drinks, and strenuous exercise that day. A gentle skin care routine keeps the surrounding skin healthy. Your doctor provides written guidance to follow once you leave the clinic.
A lip flip needs very little time, so even a 1 to 2 day visit covers the consultation and treatment comfortably. Because downtime is minimal, you can continue sightseeing 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 and avoid pressing the lips or using straws on the flight. Cabin pressure does not affect the result, so flying after a lip flip is generally not a concern at all.
International patients can have remote check-ins in English about two weeks after treatment to confirm the roll and plan repeat sessions around future trips. Because the effect is short, many time their next visit with another trip. You can also arrange complementary skin care when you return.
