Lip Flip Botox in Myeongdong, Seoul
A lip flip uses a few units of Botox along the upper lip so it rolls slightly outward. The lip looks a little fuller without adding any volume, which suits people who want a very subtle change.
Quick answer
A lip flip is a small dose of Botox, often 4–6 units in total, placed along the border of the upper lip. It relaxes the ring muscle of the mouth so the lip rolls slightly outward and shows more pink. It adds no volume, takes 5 minutes, shows in 1–2 weeks and lasts about 6–8 weeks, shorter than other areas because the lip muscle is used constantly.
What is a lip flip?
The orbicularis oris circles the mouth and slightly curls the upper lip inward, especially when you smile. Relaxing its edge a little lets the lip evert, so more of the red lip shows. It is a shape change, not added volume, so it suits people with a thin-looking upper lip who prefer not to use filler.
Who is it for?
- An upper lip that seems to disappear when you smile.
- People wanting a very subtle change, or trying lip treatment for the first time.
- For real volume or shape, lip filler is more effective.
- Less suitable for wind-instrument players or people who rely on precise lip control.
How Obliv plans a lip flip
Your doctor checks how much the lip turns in when you smile and whether you also have a gummy smile, which is often treated together. Points sit just above the lip border, spread evenly to keep the Cupid’s bow symmetrical.

Frequently asked questions
What is the difference between a lip flip and lip filler?
A lip flip changes how the upper lip sits by relaxing muscle; it adds no volume. Lip filler adds volume and shape with hyaluronic acid and lasts much longer.
How long does a lip flip last?
About 6–8 weeks, because the mouth muscle is used constantly.
Can I combine a lip flip with filler?
Yes. A small dose of Botox can enhance how filler shows when you smile.
