I used veet facial hair removal cream for sensetive skins and tested it on a patch on my face 72 hours prior to use and didn't have any kind of reaction at all, i only left it on for five minutes, when the longest you can leave it is 10 and when I took it off my face started t go very red and blister and is now swollen, red, and severely blistered and burned . It's too painful to even touch and Ive got a big dinner date with my boyfriends family tonight

Is there anything I can do to make the redness go down or help?
