Improving Dog Bite Scar on Face of a Two Year Old?

My 2-year-old daughter was bitten by a dog 4 months ago. He punctured a tiny hole in the valley between her nose and cheek. Based on size, location and infection prevention, the doctors didn't stitch. I polysporined it and it healed quickly. But she was left with a hypertrophic scar in that spot.Initially, it was raised, thick and red. I've applied Kelo-cote for 3 months, the color has improved greatly, and the skin is somewhat softer. But it's not completely gone - it's like a tiny "bubble" - particularly when she winces it pops out. What can I expect scar-wise for her? Will it flatten and smooth out?Thanks, Kayla, Brooklyn
