I Have a few mild icepick scars on one side of my face, and last Saturday (8 days ago) I used a tooth pick with some tca 25% solution on the selected areas. Last time I did a full peel all over my face with tca 25% I did two layers and left it on for only about a minute because the burning was bad. Everything peeled/flaked off in 6 days. This time I left it sit on the selected area for about two minutes and the area is scabbed still but I feel like it's taking forever to flake off. Is this normal I don't think it will peel off for atleast another week by the looks of it. Did I leave it on my face possibly too long?

Thanks
