Is There Anything To Reduce Scarring After Lip Filler Injections?

I had non permanent lip filler injected in to my top lip over two years ago.As soon as I had it done there was bad bruising on one side so she didn't inject anymore in to it. It was very lumpy so she kept telling me to massage it which I did and do.My lip is more or less the size it was before but it is very lumpy on both sides and makes me feel really sad and paranoid and I wish I'd never had it done.I don't want further surgery but is there anything I can do to help with the lumps/scarring?
