How to Treat Hypopigmentation and Hyperpigmentation? (photo)

I did a home tca 30% peel and burnt myself 2nd degree deep burns. It has been a month now and I have both hypopigmentation and hyperpigmentation and shiny plastic-like scars. I am a medium brown color like halle berry. I have been told by my dermatologist to mix 4% hydroquine with hydrocortisoid every other night and also apply retin A mixed with hydrocortisoid every other night too. What else can I do to treat the shiny pink plastic like scars and the hypopigmentations?
