Ive Recently Gotten Stitches On The Back Of My Leg

Ive recently gotten stitches on the back of my leg calf and the stitches broke. How it healed looks similar to a big dark (compared to the surrounding ethnic skin) keloid scar. I sincerely want it faded as much as possible. I am thinking of using the only thing I have which is clobetasol proportionate. Would you think this is a possible solution or do you think anything could be done? :(
