Alternative Treatments to Ice Pick Scars?

Hi. I recently went to a real good plastic surgeon about acne pitting. I have deep ice pick scars on my face, on both cheeks. For the less deeper ones my dr. did stitches, I guess it was scar revision.

It didn't just enough for the less deeper ones. But he said the ice picks are hard to treat and suggested a very expensive treatment for which I'm not ready. What other options do I have? Collagen? Fillers? I heard they would elevate the skin and make my face too puffy. Please any tips : )
