Lower Facelift to Improve Mouth Shape and Slight Sagging?

A facelift is not designed to change the shape of the mouth (nor should it be).  A stretched mouth appearance is a poor aesthetic result which can lead to some functional issues.  The downturned mouth is typically best approached by a combination of Botox and facial fillers and occasionally a localized surgical procedure.  A patient in their 30's is unlikely to be a candidate for a facelift.

A lower facelift does not
significantly enhance the overall shape of the commissures of the mouth. It is
improved, but not totally corrected. One must correct this by doing a “Lift & Fill” facelift,
along with augmenting the areas with fat injections and resurfacing with laser
if the lines are deep.

Hello,

You are definitely young by your own admission.  Often times at this age, nonsurgical options are first offered to try and help with a downturn of the mouth, such as Botox or fillers.  With early jowling and good skin, very focused liposuction can help.  Unfortunately you have not included any pictures of your face from the front in repose, so it is difficult to really tell you much more.  A skilled, board-certified facial plastic surgery specialist can give you a good set of options to help address your concerns.

Good luck,

Dr. Shah
