Why is one of my cheeks bigger than the other? If so, how can I fix them? (Photo)

Thank you for your question. Volume and contouring of the cheeks can be created with well-placed fillers (Voluma, Radiesse, Bellafill) and Sculptra. Implants or fat are alternatives. Botox and radiofrequency can help slim and contour the jawline. Liposuction can help slim the face. Ultherapy, J Plasma and rf treatments can provide skin tightening and lift. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer

Everyone has some facial asymmetry. Both implants and fillers in the cheeks can create good results for patients. Both can build up the cheeks and create symmetry. You must balance the pros and cons of each procedure and do what you feel is the best decision for you.
Fillers:
Pros: No downtime Reversible Quick
Cons: Temporary More expensive in long run
Implants Pros: Permanent Great for patients with poor bone structure Less expensive overtime
Negative: Risks associated with surgery Possible infection Downtime
Hope this helps
 

it appears that you, like everybody else, have some facial asymmetry.  Based on this photo, it is very mild and I would consider it normal. If it bothers you too much, an in person consultation with a board certified plastic surgeon with good reputation in facial rejuvenation is recommended. Good luck.

  Everyone has some degree of facial asymmetry throughout the entire face.  If one cheek bone is lower than the other, consider fillers placed in the office setting for a temporary augmentation.  For permanent augmentation, consider a cheek implant placed on the lower side to match the opposite side.  For more information and many before and after cheek implant examples, please see the link and the video below 

most people have a symmetry to their face and it is very normal. If this concerns you and you would like to try to make it more symmetric you can consider noninvasive options such as facial fillers. There are also surgical options such as fat harvest through Liposuction and then it can be applied to your face to make it more symmetric. Lastly surgical implants made of silicone can be considered.  I recommend seeing a board certified facial plastic surgeon for consultation. In Denver I would recommend Dr. Keith Ladner. I hope this helps, Dr. Farhad Ardeshirpour

 Hi, I have performed many facial shaping procedures for over 30 years.  From the photos, the one cheek is a bit flatter than the other, the chin and back portion of the jaw line appear to be weak.  These combine to create an elongated, oval-shaped face.
 Following my beauty principles, women look the most feminine, youthful and attractive with heart shaped faces.  Heart shaped faces have cheeks that are full and round in the front.  Cheek augmentation with a dermal filler or using cheek implants for a permanent enhancement will create full, round cheeks that will feminize the entire face. A weak chin creates an imbalance making the nose appear larger, the mid face top heavy and the lower face look short that de-emphasizes the lips and allows early formation of a double chin.  Chin augmentation using a chin implant will add projection to the chin creating harmony and balance to the lower face. 
 I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty.  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  In my opinion, you are a good candidate for chin implant surgery.
 The back portion of your jaw line is a bit weak and can be augmented, without making your face appear masculine, using precise placement of a dermal filler (I prefer using Restylane Lyft).
  I have performed many facial shaping procedures using dermal fillers, facial implants (cheek, chin), liposuction and/or facelifts for over 30 years.  In my experience and despite its recent increase in popularity, fat transfer (fat injection) offers "far" less of a reliable and predictable volume for facial shaping than an off the shelf dermal filler or silastic facial implant.  For that reason, I do not use fat to shape the cheeks, chin, lips or jaw line.  Tissue physiology is quite simple.  Tissue requires a blood supply in and out as well as lymphatic connections to remain viable and alive.  Once fat is removed from the body all of these things have been disrupted.  Just because the removed fat is mixed with PRP or something else doesn't make the blood and lymphatics magically re-appear.  The fat at that point is not living tissue which means that it's prone to being dissolved by the body (most likely in an uneven and unpredictable manner).  Injecting fat back into the face does not create the required elements to make the fat living tissue once again.  So the argument that fat is alive and viable in the face once it's been removed and re-injected makes no sense to me as a physician and surgeon.
 The other issue that I have with fat transfer is the lack of precision.  Fat is thick by nature which means it's not the same consistency as an off the shelf dermal filler.  Fat injections use an increased volume injected in an attempt to compensate for the volume loss that "will" happen.  This means a lack of specific shape and volume that simply can not begin to compare with the specificity of using a silastic facial implant of a "known" shape and volume.  In that regard fat offers too much of an unknown to make it a reliable and predictable method for facial shaping.  There's a significant difference between a 3mm and 5mm thick cheek implant.  You can imagine the magnitude of difference there is between retaining 60% of 25cc's of fat versus 35%.  In my humble opinion, I just don’t see how fat could possibly be used to precisely shape facial features?
Hope this helps.
