I did a TCA peel on my thigh to get rid of many stretch marks. Now I have a huge purple blotch. Is this normal? (photos)

I used a 25% TCA peel, I've used this before on my skin and it has worked perfectly until now. Day one is when the blotches started from where the frosting was. The instructions said to leave it on for 10 minutes then to add a second layer and to leave it for another 10 minutes. I washed off 3 minutes after the second layer. The photos are second day post peel. It hurts a lot and is very sore. I did the exact same thing to my other thigh and this reaction did not occur. Is this normal?
