26 is Too Young for Mid Face Lift?

Impossible to tell without seeing photos. However, especially considering your age, it sounds to me that you are overly critical of your appearance and I suspect it's not nearly as bad as you make it out to be.One's thing's pretty certain however.  You will not have a difficult time finding someone willing to give you what you want.  You should get a few consults with board certified plastic surgeons.  My personal opinion, however, is that the mid face lift by itself is a generally worthless procedure and especially at your age probably not going to be anything but a collosal  waste of money.

Although it is hard to tell without seeing your pictures what you are describing is likely to be improved with fat grafting to the cheeks, such as in the link below
