Uneven swelling 5 days after lip injection. Is this normal? (photos)

It is very likely that this will improve a lot with another week of waiting. if it persists, you can get a tiny amount of hyaluronidase injected to one side. Do not press on it or massage it, for best results.

Thank you for your question. It is very common for the lips to look
over corrected or fake the next day. I often tell my patients that this
is the "oh my gosh" day. This is due to all the swelling
that ensues. It 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.

I would suggest you wait it out for two weeks as the swelling may subside by then. You can use a pack of frozen peas to ease the swelling and keep your head elevated a bit while sleeping.
