Clinical Mechanism & Anatomy
The DAO muscle anchors at the jawline and pulls the mouth corners downward. Relaxing it allows the zygomaticus muscles to naturally lift the oral commissures.
Key Concerns Addressed
- Persistent sad or unhappy resting face
- Downturned oral commissures causing early marionette shadows
- Lip corners tucking inward
