Uneven Dark scar after Mole and Scar removal surgery. (photos)

Its been near two months having gone for mole removal surgery.But the dark mark is yet not gone. On consulting doctor I came to know its due to Hyperpigmentation. Secondly, Just below the mole there was a cut mark scar that was below the level of the normal skin layer after it got healed years ago while I met an injury. So,I decided to go for its surgery.But then,its been over a week after surgery and about to heal but the healing is below the normal skin layer.Please suggest me solutions.
