Laser burn recovery. What can I do to even my skin tone? (Photo)

I received burns from a spa using a yag laser that have resulted in hypopigmentation in the area, but I've had great results in other areas (at a different spa with different gentlelase laser). A lot of time (7 months) has lapsed and the lighter my skin, the more prominent the "striping" is. What can I do to even my skin tone? What advice do you have for continued treatment? Should I ask the spa for a refund? Is there an in home product that is more safe and effective? Sincerely, Sad In Sunny Florida
