based on my experience, the surgeon is absolutely right. I used to have severe nasolabial folds before getting buccal fat removal, because gravity pulled the fat down. The nasolabial folds practically disappeared when I got rid of my buccal fat. However, the removal of buccal fat caused slight sagging on the corners of my mouth.Today I discovered that smas facelift only addresses jowls and not the nasolabial folds! This surgeon also comments on why we get nasolabial folds! Fascinating.
