Mouth Corner Botox in Myeongdong, Seoul
Downturned mouth corners can make you look sad or tired at rest. Relaxing the small muscle that pulls them down lets the corners sit more level.
Quick answer
Mouth corner Botox relaxes the depressor anguli oris (DAO), the muscle that pulls the corners of the mouth down. Small doses, often 2–4 units per side, let the lifting muscles win, so the corners sit more level and the expression looks softer. It takes 5 minutes, shows in 1–2 weeks and lasts about 3–4 months.
What is mouth corner Botox?
The DAO runs from the jawline up to the corner of the mouth. When it is strong, it drags the corners downward and deepens the lines below them. Relaxing it is often combined with lip corner filler or marionette filler when volume loss is also present.
Who is it for?
- Corners that turn down at rest, giving a sad or stern look.
- Lines that deepen below the corners when you speak.
- Not during pregnancy or breastfeeding, or with neuromuscular disorders.

Your doctor asks you to pull your mouth down and grimace to find the DAO, then places points low, near the jawline. Staying away from the lower lip muscles keeps speech and smiling natural.
