Can the way I sleep affect my Juvederm?

Sleeping with the head slightly elevated can help resolve swelling after your treatment, and you'll want to avoid sleeping on your face for the first couple of days to minimize the risk of displacement. Other than that, you're fine sleeping however you'd like.

I recommend to all my patients to sleep on their backs for 3 nights following filler injections. This time allows the product to settle. Over long term, if you apply consistent pressure each night to one side of your face you may see a decrease in one side vs the other. Hope this helps.

Juvederm and other fillers do not move after injection. It would take heavy pressure right after injection to move it.

I advise patients who have had Juvederm injection for cheek enhancement to sleep on their backs for two days to avoid compressing or shifting the Juvederm.  Filler treatment in other areas should not be affected by the position in which you sleep.

Swelling can be affected by the way you sleep, but the filler is injected into the tissue, so no, that should not be affected by the way you sleep. "This answer has been solicited without seeing this patient and
