Scarring with discolored skin around

Patient: I had an open wound, which I treated with manuka honey. It scabbed after some days and a bit of exposure, since I initially kept it covered with a bandaid. The scab fell off a week ago, but I am left with the picture below. I have continued putting manuka honey on the area, but it doesn’t seem to be helping, it may be even getting darker. Any approximate healing time suggestions or methods to use?
