How can I treat hypopigmentation as a result of laser treatment with the PicoSure on dark spots? (Photos)

I had pico laser treatment for dark spots. I took 6 sessions. After one week from last session I start having hypo pigmentations spots on my face and its been two months there is no change and reavers in my skin tone. It’s very depressing and looking worse. I don’t know what to do and already scared from this result. Resent my photos.
