Hello, and thanks for your question. I believe you are a great candidate for lip filler. Most lip fillers last about 6-18 months and Juvederm is one of our most popular lip fillers. This can really help that asymmetry you are noticing. Make sure you are going to an experienced board-certified plastic surgeon. Please see my attached link on fillers. Best of luck to you!
