“Good result, but pretty severe bruising”

I wish there was a choice for "jury still out" on the experience instead of just YES or NO on whether it was worth it. I'm still not sure. I'm 50 and had my first two syringes of perlane injected in nasal folds and marionette lines about 10 days ago with pretty good results. I did have some slight bruising on one side of my mouth. I went back this week for a check-up and touch-up with a small amount reserved from the first session. I now have a large bruise about the size of a nickel on the left side of my mouth and it is not covering with make-up. I'm having to miss work to avoid the questions and it's bad timing. My Doctor suggests another two syringes for best results and they're running a BOGO special end of this month. I'm torn whether to do it again or not. I'm going to say it was worth it because I saved up for this and am hoping for a great outcome once the bruising goes away. How do I avoid bruising in the future? Home remedies are not working after the fact.
