Fig. 3.

A frontal view comparison of facial lines before (A) and after (B) lip augmentation with improved facial features. The numbers displayed are average changes in lip dimensions as per our study, not the actual measurements for this specific individual (A) before and (B) after the lip injection. The red lines indicate the vermilion borders of the upper and lower lips. The blue lines mark the area where the vermilion zones of the upper and lower lips touch, typically the point of fullest pout. The green line delineates the oral commissure, the corner of the mouth where the lips meet.
