I was on the Nivea website and saw they had two different versions of the sensitive aftershave, one as a lotion and one as a blam: http://www.nivea.com/products/show/111. This led me to question what exactly a balm is, I've never really understood that word. Anyway whats the difference between the two? And what the hell exactly is a balm? I know we all use one but why are they called balms and not lotions/creams/aftershaves? (BTW I know I am very sad for wanting to know the answer for such a meaningless question but i've always been the weird daydreaming philosophical type)
