How Do I Fix Sagging Cheeks and Facial Asymmetry? (photo)

Hello,

  Thank you for including photographs with your questions.  It makes meaningful discussion a little more attainable.  Everyone ages a little differently, but generally speaking creases and lines gain visibility in the middle to late twenties.  You have very healthy appearing skin and a reasonable first step would be to consider injectable fillers.
 
  Precise and artistic application of fillers around the folds of the nose and mouth can make a dramatic improvement.  Both Radiesse and Juvederm work well in these areas. 

  One thing to consider is that there are asymmetries between the right and left sides of your face, with the right side being slightly more developed then the left.  Asymmetries can be improved, but will always exist.  Asymmetry is perfectly natural and adds to one’s unique beauty.  
 
Hope this helps.

Malar implants, fat injections, and fillers are all options. Make sure you go to someone who does all of them because if they don't they will lead you in the wrong direction.

At your young age, I would suggest trying nonpermanent fillers first. If you like the look, consider an implant once the fillers wear off. If you don't like the look, it will be gone within 9 months.

At your age I would recommend you consider a trial of fillers and if you like it then possibly fat grafting before looking into surgical options.
