Follow-up question: After Volbella, my lips have turned brownish and purple. Should I be concerned and is there a way to fix it?

I recently got lip injections of Volbella and my lips have turned brownish also purple (they are actually darker in real life than the picture!). This happened before but I thought it was because of a medicine that I was taking that I reacted poorly too. I am not sure why they became this color??? Should I be concerned and is there a way to fix it??? I hate how they look now! I wanted my lips to look bigger by the brown makes them blend with my skin making them look smaller!!! Please help!The first image is a before and after. My lips were very pink with hardly any dark or brown pigmentation. I spoke with my injector and she said possible post inflammatory hyperpigmentation, is there any way to correct this? Because the first time I got fillers it never actually completely went away, only faded (which is part of the reason that I wanted more).
