I did microneedling + mild chemical peel 3 days ago. Is this normal healing or a burn? (photo)

She went extra over this area with microneedling b she said that’s where my scars are deepest. I was weirded out that the peel was put over my skin right after microneedling. She wanted to microneedle more w the peel on but I refused, she removed it after about 2 minutes and said it was a mild peel. Today is the 3rd day, now have this brown scab/pink under. Was told to come back for another as soon as my skin heals rather than waiting 4 wks.
