[1][2] The American Society of Plastic Surgeons reported 3.2 million cosmetic surgery procedures performed to mature patients, aged 55 years and older, in 2008.
The patient demand for facial rejuvenation indicates that most requests do not include the mouth, which results in a surgical outcome that is aesthetically deficient.
The incisions remove tissue and significantly alter the shape of the lips by moving up the vermilion from both peaks of the Cupid's bow outwards to the commissures, the corners of the mouth.
[2][9] Depending upon the indications of the patient, this technique can increase the drooping the corners of the mouth (commissures); thus, the sub-nasal lip lift often includes a corner-lift surgical step.
[citation needed] Another variation of the procedure consists of a lenticular excision of the white skin surrounding the upper oral commissure in order to lift this part of the lips.
Quantitative data exists for the V-Y lip augmentation, for which statistically significant increases in upper vermilion height and surface area have been measured.
In particular, the technique of removing skin at or directly above the white roll has been singled out as resulting in unfavorable scarring and stiffness in the lips.
