Why is my left cheek bigger than my right cheek? (Photo)

You have a very pretty face but asymmetries in every patient are present... if you look closely enough.  The question then becomes which are reasonable to treat?That being said, minor irregularities can be addressed with a number of fillers.  Your doctor should have an artistic eye and notice the differences, including the accompanying differences such as with the cheeks, eye bones, orbital set, brows, mandibular border, etc. that often go hand in hand with cheek asymmetry.

Dear Jazzer1928,Thank you very much for your question and the photo that you included.  It is not uncommon for people to have more facial tone on one side of the face than the other.  This means that there smile may be wider on one side than the other or that they are more expressive on one side than the other.  Additionally your left cheek bone is smaller than your right, and your left eye is a little bit lower than your right.  Clinically speaking you have a subclinical hemifacial microsomia.  This means that one part of your face is a little bit smaller than the other and you can only tell when you look really close.  Pragmatically speaking you have a very natural, youthful, and beautiful face.  Sure, fillers could be placed along the left cheek bone region to create better facial symmetry.  This would limit the tissues slightly on the left side and create more symmetry.  I hope this is helpful to you.Be healthy and be well,

Everyone has some facial asymmetries. Facial symmetry can be improved with well-placed fillers (Voluma, Radiesse, Perlane, Bellafill): Sculptra, implants or fat. I recommend getting a consultation with a facial contouring expert. Best, Dr. Emer

Hi Kateeester,
Thank you for sending your question and photo! Many patients are concerned with asymmetry, but it's good to note that some facial asymmetry is common.
A skilled injector with an artistic eye should be able to Non-Surgically reduce this minor appearance of asymmetry and create improved balance between the two halves of the face. The process involves injecting dermal fillers such as Juvederm Voluma to add volume and improve the facial profile. 
It's beneficial to be examined in person by a dermal filler specialist. Be sure to do your homework and find an Injector with demonstrated patient results and experience.  
I've created a video about Non-Surgical cheek augmentation to address some frequently asked questions about the treatment.
I hope this information helps in your research!
