2% salicylic acid left on my skin too long, and now I have burn marks on my face. what can I do to minimize scarring? (photo)

Hi! 12 days ago i used clean and clear mark treatment with 2% salicylic acid on my pimple mark. I left it overnight, woke up with dark burn like marks on my face. I used aloe vera gel and triple antibiotic oint and 10 days later the burn like scabs fell off revealing a pink skin with a dark discoloration around the new skin. Ive been keeping it moist with vaseline and aquaphor, but im scared it will leave scars :( what can i use or do to minimize scarring? How long will it take to heal?
