After getting lip injections & not keeping up with them as often as some, will it cause your lips to look deformed?

Lips will go back to their normal shape once the filler is gone. If you do not "keep up" with injections there is not consequence.  Best, Dr. Emer.

The beautiful thing about these cosmetic injections is that if you are unhappy or choose not ton continue with these injections, your lips will return to their original shape and size.  Best, Dr. Green
