Still black/Blue after filler almost a month ago! I'm worried this is permanent.

Dermal filler to raise an indented scar in cheek. Severely bruised. I went back after a week, they said it was just bruising. I was worried it was Tyndall so they used some Hyaluronidase. It didnt go away, so I thought okay, maybe it is a bruise. That was 3 weeks ago. Still black/blue. Im worried this is permanent. I love the correction and would hate for my scar to return to the horrible way it looked pre-filler. Black on my face is upsetting and impossible to cover with makeup. Help!
