Why is the right side of my face wider/rounder than my left side?

Thank you very much for your question. On the first part, the asymmetry you described could indeed be due to your jaw and the way the teeth align. However, there are other causes and you’ll need a formal consultation to determine the diagnosis. The second part, fillers are likely your best options to treat your asymmetrical facial structure without surgery. See an expert. Dr. Aldo

It's hard to confirm the cause of your asymmetry without evaluating you in person. Facial asymmetries are common and can in many cases be improved using a combination of fillers and Botox/Dysport. 

Thank you for this question!  I get asked this daily at my office, and I always make note during consultations of the person's asymmetry.  Everyone is asymmetrical.  It just varies in degrees and reasons why.  In my experience the use of fillers have been a great way to help balance and create a more symmetrical face.  In any case, you do need an in person consult for exam to determine your reason for asymmetry.  I hope this helps!  
Best of luck,

It is very common for people to have asymmetric faces. This can be due to several reasons - genetics and facial volume loss as we age being two of these reasons. You may have asymmetry at baseline due to your genetics (your eye possibly being smaller on one side than the other), but you also can have asymmetry from facial volume loss as we age that is making it look worse now than it did a few years ago. I often see patients with more volume loss on the left side of their face compared to the right side due to the sun hitting the left side of our face when we drive - this chronic sun exposure can truly break down our collagen and make our left side of our face more depleted. Wearing sunscreen (and reapplying regularly!) will definitely help with this. Also, sleeping primarily on one side of your face compared to the other can cause volume loss as well - sleeping on your back is ideal as it helps to prevent this. You may have a combination of genetics, collagen breakdown from sun exposure, and volume loss from sleeping on your side contributing to the asymmetry. A great option for treatment would be dermal fillers to give you a more symmetric appearance. No need to jump to plastic surgery for this!

Hi Lilly593, Please don't worry. All of us have facial asymmetry one way or the other. Botox can be used to even up the eyes and also decrease the masseter size on one side. That being said, please visit a dentist who can correct your jaw and bite. Fillers can help with your lips as well.All the best, Justin Harper, M.D.
