Would a Zo skin health 3 step peel or chemical peel help with my hyperpigmentation? (Photo)

I have hyper pigmentation on my face and neck from sun damage. As you can see in the pictures below my face and neck is a lot darker than the rest of my body. I know most people faces are darker but mine is several shades darker. I have seen some results of the ZO skin health Obagi 3 step peel and I was wondering if that would help? Would the results be permanent or temporary? Are there any other solutions out there that would be permanent? Are there any recommended doctors in Chicago?
