How to treat post-inflammatory Hyperpigmentation?

Last summer I burnt my leg with oil. Reddish stains appeared after when the wounds healed and they are not disappearing to this day. Doctors diagnosed Postinflammatory Hyperpigmentation. Could you recommend the best treatment for the stains so they'd disappear or at least they'd be less visible? How do they react to sunlight? What do you think about laser (Fraxel DUAL 1550/1927 nm) procedure as a treatment?
