Will Open Wound from Surgical Acne Scar Treatment Fill In?

What if a wound that had sutures for 6 days, steri strips for 5, opens up? Now I have this gap, rather than 2 acne scars. It has been 4 weeks, and I don't know if it will fill in.

Unlike the acne ice pick scar that didn't fill in, is this the type of wound/scar capable of filling in? I was told that he put sutures underneath as well as the few on top.

I had Total FX, 4 months ago; but it did nothing for the acne scars. I opted to have this done, figuring a fine line would be less noticeable than a hole. I called office on day 12, and said it was open. The nurse said it will take time to heal. The plastic surgeon doesn't even want to see the scar until 3 months.
