Do I need a corner lip lift?

Thank you for your question. At the age of 16 I would advise against plastic surgery, you are still growing and your appearance will continue to change over the course of the next few years. Your lips are full and have great symmetry, I would not suggest altering with surgery.

No and no.First of all, at your age, no plastic surgery at all is indicated, unless you have some significant cosmetic deformity which you do not.  Second, while I regularly perform lip lifts, I do not perform corner lip lifts due to the scarring that can result.

At your age of 17 the answer is no. Wait until you actually need cosmetic surgery before you venture in that direction. also, you lips look fine.Truly, you have great looking lips. don't touch them. You are looking at yourself too critically.
