It says right on the label "Do not use on damaged or broken skin". This is news to me. I thought that's why most people used it. MY WHOLE LIFE IS A LIE! I'll get a cold sore from time to time. I have ever since I was kid. My mom  always handed me Carmex to treat it. The same thing with chapped lips. Chapped lips definitely count as damaged skin as far as I can tell. Will someone please explain this to me, or am I the only person who's sitting here wondering why something I use on my damaged skin is telling me not to put it on my damaged skin? To me that's like saying that life jackets are not to be used as a flotation device. Peanut butter isn't to be paired with jelly. Sugar should never be inserted into a tall pitcher of kool-aid. What the hell man!
