I did a 40% peel on my face and neck. I knew something right away was wrong because the frosting was like snow covering my face and neck not frost. And the pain was excruciating..I left the tca on for about 90 seconds or less. The frosting lasted about a half hour then my skin turned maroonish/brown .I have light/olive skin. the next 12 hours some of my skin actually peeled and it was raw red...
