Can you help me find a treatment for this dark spot on my cheek? (photos)

I have a dark spot on my cheek and it has been here for about 7 months. It started from a cyst like pimple that I could not pop and resulted in hyperpigmentation and a large ice pick like scar in the epicenter on my cheek. I have tried bleaching cream and it seems to turn my scar a reddish brown that looks irritated. With shea butter i have gotten the most results but now it is a grey brown, not yet leaving and I'm not sure if it's healing.
