Thank you for your question.The decision to enhance your lips is something only you can decide. If you think it is something you would like to pursue, I would suggest something temporary like Juvederm. You can start gradually and see if you like it. If you like the results of Juvederm and want to go for something more permanent there are other options. I would suggest contacting a PS in your area, to discuss your options in person. Good luck.
Thank you for sharing your question and photograph. The decision to pursue any aesthetic procedure is up to the individual and depends on your desired goal outcomes. Instead of deciding whether your lips are big or medium sized determine if you'd like to subtly enhance your lip appearance. If you do, see an ASPS board certified plastic surgeon in consultation to discuss your treatment options. Hope this helps.
