How quickly does Hyaluronidase work to remove lip filler, will it remove all filler and does it effect your normal tissue?

I want to have some of the filler in my lips removed. Will everything be dissolved or is this dependent on how much my doctor uses of the Hyaluronidase? I don't necessarily want to have everything dissolved but im OK if that's what has to happen. I'm hoping just a little can be removed. I've read Hyaluronidase can dissolve my real tissue, how true is this as this is more my real concern and I don't want to have dents or lose my own tissue.
