What Really Works in Improving Skin Discolorations?

My skin has improved dramatically over the last 6-8 months, but I still have red and brown pigmentation in certain areas of my face. I'm wondering, what really gets rid of this?

I have money for the procedures, and I have no problem with downtime. I hate always having microdermabrasion or similar things suggested to me. It's important that they are minimized or removed, so what does really work for skin discolorations, especially  red and brown pigmentation? What is often touted to work but really doesn't? Thanks!
