Lip augmentation is best considered as a proportion problem rather than a target volume.
The upper and lower lips have different shapes, landmarks and relationships to the teeth, nose, chin and surrounding face. A useful plan respects those relationships rather than treating the lips as isolated structures.
What matters
- Baseline lip shape and asymmetry.
- Desired change in definition versus volume.
- Dynamic movement and smile.
- Prior fillers, implants or permanent materials.
- The reversibility and risk profile of the chosen technique.
Patients with prior permanent material or complications require a different discussion from first-time augmentation.
