Restylane--how long before it dissolves and does it leave scars?

After the Doc injected me with Restylane 2 weeks ago I had a caterpillar-like line on my forehead which looked dreadful and much worse than my superficial line. I also have a blue-tinged swelling on my left "smile" line. He (painfully) massaged the line on my forehead, which made it a little better--but I still prefer my natural lines. He decided not to touch the side of my mouth--which was a bit bluish. I'm angry, and I may have to go back to have whatever magic injection needed to remove it. He didn't mention a reinbursement and I'm not sure as to what my rights are. He did tell me that it would eventually disappear, though. I'm so worried now that it will leave permanent damage. Will it cause the skin to form a scar around the Restylane filler if I choose to let it dissolve on its own? Thanks. Lisa
