Mohs surgery on forehead 3 weeks ago, and the dissolving (gut) stitches did not stay closed (Photo)

The outer stitches opened after Moh's, and I have an opening on my forehead (approx. 1/2 inch). The wound is open and red, but it isn't bleeding much and doesn't feel inflamed. I've been using Vaseline and a bandage to cover for 3 weeks. I want to know the best method for healing this wound from now on. Should I stay on this aftercare routine, or leave the wound open as is? Thank you.
