Burns/Scarring after Salicylic Acid peel 30%? (Photos)

I has a chemical peel yesterday at home - salicylic acid peel 30%. Last session I had was last week . But this time my face is all scarred. Is it some reaction (as I am applying benzoyl peroxide on my acnes) ? or Is it burn from a deep peel ? What should I do to heal it ? Is it going to remain as a scar ?
