I'm 3 days post juvederm and I don't like the fake looking result. What can I do? (Photo)

You are still very swollen. It can take 2 weeks for the swelling to improve. If you still don't like your lips after 2 weeks then the Juvederm can be dissolved using Hyaluronidase. Best wishes.

I always tell my patients to not love their filler
injections for 2 weeks. Swelling is very common and sometimes immediate. It can
last 3-7 days and a good idea is to use cold compresses. Cold compresses may be
used immediately after treatment to reduce swelling only if needed. This may be
applied for 3 minutes, 3 times per day, for up to 3 days. This is best done
with a bag of peas in a zip lock bag. Only apply light pressure to the area but
gentle massage might be necessary if the bump is from the filler material
itself. Get Arnica gel if you can find some and apply a few times a day as well
to help treat any swelling. Avoid any blood thinners. Bruising can also last
1-2 weeks. I don't recommend hyaluronidase this early and wait a few weeks
until the swelling has resolved. If it is persistent or you are worried, set up
a follow up appointment with your dermatologist.

This may be mostly swelling that can take 1-2 weeks to resolve in the lips. If it doesn't improve sufficiently, the filler can be dissolved.
