Although it claims to not be addictive, I am sure they put something in Carmex Lip Balm! It smells kind of funny, but is amazing-I have been using it for nearly 10 years and never had a cold sore. As it is so cheap in America I always get a large stash over there, but it last ages, so I now have excessive amounts lying around me bedroom, that make me look obsessed. I am LOVING there new strawberry one, which I stupidly only brought one of and have now lost (bad times). Would defiantly recommend, but just remember, once you start, you wont be able to put it down! If you have an addictive personality, maybe this isn't the lipbalm for you.
