The lips create a frame for the teeth, just as a picture frame does for a piece of art. The shape of our lips will also change when moving from rest to a full smile. If the lips are asymmetrical, the resulting appearance can be uneven and disproportionate. If left untouched, the asymmetrical lips will age and continue to lack volume.
The presence of small or asymmetrical lips is noticeable and may be emphasized when a patient smiles, speaks, or laughs.
