Burnt my Face with a 30% Tca Peel, What Can I Put on It to Prevent Scarring? (photo)

I am half black, half lebanese and tried to do spot treatment on my ice pick/boxar acne scars and unfortunately burnt my face pretty badly. I went to see a dermatologist and was told to put vaselind during day and hydrocortesoid cream at night for 2 weeks. Today is 12 days and burnt skin has peeled and the skin is pinkish reddish in color. I had no blisters but on day 1 skin was just bright pink and day 2 medium brown and day 3-6 dark brown to black charred burnt skin. Please help.
