Which laser would be the best choice to improve the appearance of hypopigmentation across my forehead? (Photo)

I have used tretinoin cream in the past with little improvement. I put on sunscreen and wear a hat when I am outside. I am trying to decide the best course of treatment to even out my skin tone. Fraxel Repair, Fraxel Restore, Non ablative Fractional Erbium laser vs Ablative, IPL. There are so many choices out there. I would appreciate any and all suggestions. I have included 2 photos, views in different lighting.
