Sleeping vs lips Juvederm

It is unlikely that positional changes would be able to shift filler that has been placed. On the other hand, if one is sleeping on one's side, the side that is down may experience more swelling than the side that is. That may translate into some swelling on the downside when you wake up which can be concerning. This usually evens out after a couple of hours.

Thank you for your question.  Because there are no studies on this (and there aren't likely to be any, anytime soon), you will hear different answers from different doctors based on what makes sense to them.  Usually after injections, physicians will massage the lips.  This is to even out any irregularities and make sure the filler is nicely distributed.  This requires a fair amount of pressure.  This is because its not easy to get the filler to move anywhere even immediately after its injected.  In my opinion, sleeping on your side is highly unlikely to move the filler even a little bit.  On the other hand, if you sleep on one side predominantly, you may notice the side that was down gets a little more swollen over night.  This is just "dependent edema" and will not alter your outcome.  Just don't sleep directly on your lips for the first few days.  All the best!

At this stage there is no real scientific evidence to determine whether sleeping in a certain position for several days after your injections will in any way optimize your results. At this stage, you should be able to sleep in the most comfortable position and not worry too much about shifting your lip filler. Remember it can take several days for the swelling to settle down! 

Thank you for your question.  I am sorry you are experiencing this problem.  As Dr. Yoo explained there is likely very little information out there regarding position and effect on your filler, and your are likely to receive different opinions.  In my experience, it is highly unlikely positional changes will effect the placement of filler anywhere in your face including your lips.  There may be increased swelling due to position but this will likely resolve over the next few days to weeks.  Concerning your pain in your back, this may be due to the position your physician had you in while performing the filler especially if the procedure took an extended period of time.  While this is unusual sometimes people tense up their necks and backs while having procedures done and that rigidity causes stiffness and pain later. It is more common in the next than back in my experience. Since you are in university and studying a lot, this stiffness may be compounded by the combination of the procedure and hunching over to study, making it particularly bad for you.  If you are not improving, it is important to follow up with your physician, as neck or back pain can be a sign/symptom of some other underlying pathology.Hope you feel better and thank you for your question.  Regards, Dr. Matthew Elias
