Why are my lips slanted/crooked? Is there anything I can do to fix it? (Photos)

bri1 102. I appreciate your concern but your asymmetry may be related to your braces.  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!

Thank you for sharing your question and photographs.  Some lip and facial asymmetry is the norm rather than the exception and I would not recommend much treatment for you based on the fact that you have very symmetrical and full lips when in repose.  When you smile it appears that one side of your mouth "pulls"  a bit stronger than the other and attempts to correct this would not only be unlikely to work but also change your resting lip position. 

Dear Bri1102,it is hard to tell without an examination. Generally speaking, dermal fillers and Botox can be used to address crooked lips. I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.Daniel Barrett, MD, MHA, MS
