Developed Post Inflammatory Hyperpigmentation, Which Are My Options For Fixing This?

I developed PIH on upper lip about a year ago after doing microdermabrasion & hair cream bleach on the same day. I would like to use hydroquinone, but unfortunately some people are too sensitive. Which topical treatment is better, Lumixyl or Elure? I am Caucasian with dark features (dark eyes & hair). Can the Fraxel Thulium 1927 laser help without inducing further PIH if I pretreat skin for 6-8 weeks? Im not going to do Fraxel Dual 1550&1927, just the 1927. Can this laser reach PIH? Please help.
