I used to use Carmex constantly, but my sister warned me that it was indeed addicting so I started buying Blistex instead. It seemed that the Blistex dried my lips out so I started buying a lip balm made by Aquafina. It's lovely and smells delicious!
I think she said that the Carmex is addicting in the sense that it dries your lips out so that you have to continually apply it but because it makes your lips tingle when you put it on, like Blistex, it makes people think that it is healing their lips.
