Will lip filler be nice for me and make me look pretty? (Photo)

Thank you for your question and series of photographs.  Based on your pictures alone I do think that a dermal filler, such as Juvederm can help achieve a better balance between your upper and lower lips.  Be sure to see a board certified plastic surgeon in consultation.

You have very nice lips, which if you want them bigger, will improve your chances of an excellent outcome.  Don't let a surgeon tell you what you like.  If you want your lips larger then find a surgeon that knows how to give patients what they want.

You do have nice fullness in your lips now, but if you want them larger, I would suggest using a filler like Juvederm.  When you go for a consultation, please ask to look at photos.
