New discoloration cure
MacGyver Tip: Heal warts with duct tape
The idea is that if the duct tape kills the skin underneath it, new (better looking) skin will grow in it’s place. One of the comments on the page mentions his skin "turning white" which sort of reminded me of what happens after an acid peel.
I have not tried this yet, but I might. Actually, the nail polish idea seems more appealing.
