Mouth Corner (DAO) Botox in Seoul

Mouth Corner (DAO) Botox explained

Mouth corner Botox, known in Korea as 입꼬리 보톡스, treats downturned lip corners. A small amount of toxin relaxes the DAO muscle on each side of the chin. The aim is a more neutral or slightly lifted resting mouth, not a fixed smile.

How Mouth Corner (DAO) Botox works

The DAO muscle runs from the jawline up to the corner of the mouth and pulls the corner downward. When it is strong, it creates a frown at rest and deepens marionette lines. The doctor injects a small dose low on the muscle, near the jawline and away from the lip. With less downward pull, the lifting muscles of the mouth can hold the corners higher.
