Why did my punch excision fail? Should I re-excise? (Photos)

PS did a 2mm punch on small ice pick. Stitches out after 7 days but I was left with a hole. A month later, he reco'd a re-punch. Said that he wouldn't have to make the hole any bigger;just take out the 'core' again. Now it's still indented and looks bigger than 2mm. Tried Esthelis filler 5x (last time in March) but it looked terrible; donut effect though it's not tethered. Also did 1x frac CO2. Re-excise? Dermasanding/dermabrasion? Filler again? Help!! It's seriously killing my confidence.
