Dark shadow after a filler in my nasolabial area (Photos)

Hello I had a filler injected to my nasolabial folds around nov 9 the problem is that I look like I have a dark shadow on one side I don't know what the cause of this is I can figure out if it's the filler or do I have blood that turn black what are the solutions to this? Last week I went to a dr. To see if I could get this issue fixed he offered me two options inject more filler or dissolve I told him to inject more to try and even out the lump I had so I had one syringe of juvederm injected
