A scab grows over the wound and then heals.
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.
There's really nothing you can do about that. The scab will fall off when the skin underneath has healed, which it will do at its own rate that can't be hurried. If you pluck the scab prematurely you will be left with a new sore, which tends to make the final scar bigger and more visible than if you left the first scab alone.
