I think I may have burn from 40% mandelic acid. Any suggestions? (photos)

I gave myself a 40% madelic acid peel last night but did 2 layers left on for 2 min...it started to frost which I strange for a non tca peel...and my skin started to turn red...I immediately washed off . Today still red patches that I hope just turns brown and then skin falls off but I'm a little worried...is this a burn? What can I put on it? Is tretinoin okay?
