A lip lift is a plastic surgery procedure that modifies the cosmetic appearance of the lips by reshaping them to increase the prominence of the vermilion border; and to enhance the facial area above the lips into a more aesthetically pleasing shape. In corrective praxis, a lip lift procedure is distinguished from lip enhancement, the augmentation of the lips, which can be effected with a non-surgical procedure. ==Background== ;Techniques There are surgical and non-surgical techniques for effecting lip lift and lip augmentation to the lips. The surgical techniques include incisions below the nose and in the periphery of the lips area of the face, the perioral area; other techniques effect the surgical incisions from inside the mouth. ;Surgical aesthetics The aesthetic ideal of a mouth with youthful lips — shaped like a lozenge — features an upper lip with a pronounced Cupid's bow, and much fullness to each lip; however, such an ideal physiognomy declines with age, and the lips shrink and lose anatomic definition, as the lips sag, which affects the aesthetics of the smile, by revealing less of the teeth during a relaxed smile.〔〔Austin HW, 1986.〕 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.〔Fanous N, 1984.〕〔Aiache AE, 1997.〕〔Wilkinson TS, 1994(a).〕〔Rohrich RJ, et al., 2000.〕〔Weston GW, et al., 2009.〕 In the 1980s, when collagen, originally the principal filler for the lips, proved limited in effecting permanent correction, plastic surgeons then developed surgical techniques for lifting and augmenting the lips, and correcting aesthetic defects and deformities.〔Jacono AA, Quatela V C, 2004.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lip lift」の詳細全文を読む スポンサード リンク
