After Restylane injection on chin, dark bruise, am I in danger? (photos)

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.

It is not unusual to have some type of bruising or swelling
to the injection site. This is temporary and should starting fading over the next couple days. Technique with fillers can affect how much bruising one gets. I use a blunt tip cannula for all of my fillers.  The benefit of this is that in contrast to a needle, the cannula pushes blood vessels and nerves out of the way without causing trauma. Most of my patients don't experience bruising at all because of this. In the future, see if anyone in your area is using this technique because it can markedly improve your experience. It is also far less uncomfortable during the injection. If symptoms get worse please contact your provider.
