Uneven Swelling with Juvederm?

Thank you for your question. It is very common for the lips to look
over corrected or fake the next day. This is due to all the swelling
that ensues and it can affect one side more than the other.I often tell my patients that this
is the "oh my gosh" day.  It can be 'oh my gosh' my lips are so
swollen! It could also be 'oh my gosh' I love my lips even more than
yesterday. Either way, the swelling may last a few days with every day
showing a decrease
in swelling. The more you ice the first day or two, the less swelling
you will have. I would wait a few days to a week and then return to
your injector if you still have concerns after that. If you like the
look of the lips at some point during the swelling reduction, then take a
picture. This way you know what volume you like in the lips for the
future.

Swelling can definitely be asymmetric. Fortunately, it will resolve over the next few days (although sometimes it can take a week or two). 

  The first several days after Juvederm injection to the lips swelling can be prominent and, if bruising is present, this swelling may last 2 weeks or more.  I generally recommend at least 2 weeks before reinjection of Juvederm to the lips.  Kenneth Hughes, MD Los Angeles, CA
