Swelling and bruising often happen after fillers and really should be
expected. In the lips the skin is very thin so bruising and swelling can
often be worse than in other locations. Here are some
suggestions: 1. ice it on and off (do not freeze your skin), but ice on
and off for the first 24-48 hours; 2. take Arnica (available at heath
food stores) and/or apply Arnica cream too; 3. keep your hands away from
the area (pressing on it can make swelling worse, and can also move
product); 4. sleep a bit elevated. If you don't like the shape or fullness after all swelling is gone, then you can assess with your injector whether you may or may not need some hyaluronidase.
