Face is discoloured and almost purple post chemical peel? (Photos)

Today I got my 2nd chemical peel @ a reputable location by an experienced aesthetician. About 2 hrs after my peel, I noticed discolouration in the areas (dark purple/brownish colour) where I already had scarring. I called the clinic & she told me this was normal & when I start peeling, the discolouration will go away. I was also told not to wash it off until I wake up next morning. This never happened the first time so I'm worried. I'm not sure what type or % peel she uses. Attached are pics.
