It turned black: because you created a blood scab. It has persisted for 3 weeks perhaps because you are picking at it. This will cause the inflammation to become chronic and increase likelihood of scarring. The best thing for you to do is use a gentle facial cleanser (do NOT scrub), 2.5% benzoyl peroxide, and a light facial moisturizer everyday, and LEAVE IT ALONE. Seek dermatologist advice if that fails.
