The muscle from the corner of the mouth down to the jaw is called the depressor anguli oris (DAO). The action of this muscle is to pull the corners of the mouth down, causing the mouth corners to turn downwards.
Drooping mouth corners can be lifted by treating the DAO muscle (shown below) with anti-wrinkle injections. We use 2-3 units to each DAO muscle which provides a subtle lift to the mouth. The lifting effect is likely to last for up to 3 months.

Dermal fillers to treat mouth corners and marionette lines
If the mouth corners are turning downwards we often recommend dermal filler to provide a lifting effect. Dermal fillers provide structure and support to the lower face – like scaffolding propping up a building.
Dermal filler lasts up to 18 months and is a great addition to anti-wrinkle injections to treat drooping mouth corners.
In the video below Bianca Quon from Cityskin discusses how to treat the marionette lines with dermal fillers.
