About 5 years ago, I had a recurrent mucocele on my bottom lip (always in the same spot). It was caused by biting my lip when stressed. I stopped that nasty habit, and the mucocele hasn't come back since. I'm interested in getting lip fillers, possibly restalyne. Will the process of getting the filler cause the mucocele to pop up again? And if so, could it make the mucocele even larger?
