The blood clots; leaving a scab. Then the body grows skin under the scab; once healed the scab falls off.
They can scab over and once the scab falls off, the ink may fade where the scab has been.
The skin usually appears pink when a scab falls off. If the cut was deep enough, a scar may also appear in its place.

you don't have to do anything. that's a new skin under your scab. it will get old after some time too and return to normal.
If left alone - when the skin has healed underneath it.
Only with time. It will fall off. If you pick it off, it will bleed, and then it will take longer to heal.
