Is this a burn on my knees or a normal process from a chemical peel? (Photo)

I did a 25% chemical peel on my knees two days ago but parts of my skin are very dark red and hurt. I did two 10 min layers but no frosting then on the third I immediately frosted so I neutralized and then got in the shower so the water could hit it. Now my knees are so dark and red and it hurts with no peeling. The red marks are not even hard it just looks like carpet burns! Will this heal properly or did I give myself a chemical burn? I've been applying neosporin.
