Why do some women get "duck lips"?

Plain and simple that is how they were injected.  Choose wisely.  This is your face, don't go to a bargain basement spa; you might just get what you paid for.Dr Rodger ShorttPlastic Surgeon Oakville OntarioAssistant Clinical Professor & Director of Cosmetic Surgery Training,McMaster University

This is a great question. There are a few reasons why women end up with duck lips after filler injections. The most common is that too much filler is given to the top lip and the normal anatomy of the lips is ignored. Some of this has to do with the experience of the injector. Believe it or not, some women actually come in asking for that type of appearance, which I refuse to do.
