The injection technique for Perlane differs from other fillers because of its viscosity. If you don't like the result, the benefit is that hyaluronidase can be used to dissolve this hyaluronic acid filler.
What I love about all hyaluronic acid fillers (including Perlane) is that they're fully reversible. If you're unhappy with its placement, ask your doctor to use hyaluronidase (i.e. Vitrase) to melt the product away.

I don't know why you would have hypertrophic scarring after fillers. Can you post photos? This makes no sense. What do you mean the Perlane was "flung about an inch around my mouth"? Do you mean injections were done into your marionette lines? Perlane is normally injected into the deep dermis or superficial subcutaneous layer, but it depends on what area is being injected as Perlane is used in many locations. The same depth normally wouldn't be used in all areas. So if your injections are .5cm which is 5mm, it's in the deeper dermis layers and superficial subcutaneous layer, which is the proper injection depths. If you don't like your results, you can remove the Perlane with hyaluronidase.
