How to fix an ugly smile - crooked upper lip. (photos)

Please don't stop smiling just because you are self-conscious about the asymmetry of your lips. First, it's perfectly normal for the lips to thin out during a smile. The cheeks also usually look fuller.
 
In repose, your lips are quite attractive. Very precise and judicious use of hyaluronic-acid dermal fillers such as Volbella and Restylane Silk can be expertly applied to make your lips look more symmetrical when you smile. And although this may sound silly, you can try practicing a smile in the mirror that looks more flattering. Movie stars and models do it, so why not you? Consulting with a board-certified dermatologist will give you a better idea of the improvement you can expect with Volbella or another dermal filler.

Dear a55555,From the photos you have posted, injectable fillers will help bring symmetry to your smile. I would recommend using a conservative amount at first, and then using more as needed in order to avoid further asymmetry.In addition, I think you would benefit from Botox placed in the masseter muscles of the cheek to give your face a slimmer, more defined look. When you are ready, please look at before and after photos on my website and we can set up an in-person consultation to address your concerns and answer all of your questions.Best regards,Nima Shemirani

Your asymmetry is only apparent when you smile, so correction must be done with great care because your lips are quite attractive when in repose. I recommend correction with a filler like Juvederm Ultra plus by an experienced injector very conservatively because over correction will cause another asymmetry. If you like the result, then you can consider fat transfer for a longer lasting result. Seek out a board certified plastic surgeon or dermatologist with lots of experience treating lips. Good luck!
