Post inflammatory hyperpigmentation - no resolve (Photo)

I developed folliculitis from shaving some years ago. I took antibiotics to resolve it however I now have scarring in the form of light brown pigmentation which really bothers me. The pigmented scars are slightly raised and can be felt when I run my hand over the area. I have tried various treatments with no success - chemical peel (lactic/glycolic acid I assume), Alexandrite lazer, fraxel lazer and lightening cream. I would really love to know what is worth trying to eleminate this scaring
