Burn from chemical peel?

I got a 50% gylcolic peel & the acid had dropped onto my lower face area and left a rash, the rash then got bit of acid on the next day, after a week or so turned into a red mark possible a burn,a scab then formed however I foolishly picked it off, there was no bleeding or anything I used different lotions such as Vaseline, aloe Vera& aquaphor it has been 22 days & it still looks very red and it is slightly indented in my skin, I can't visit a expert so any at home tips would be appreciated!
