This is a more confusing issue. Some products are meant to fight odor, some are meant to fight sweat, but some prevent both. Think about what your main problem is and buy something tailored to solve that specific issue. If you’re sweating a lot, buy an antiperspirant. If you don’t sweat that much but the smell is your problem, buy a scented deodorant. If you are affected by both these issues, as most people are, then go for the scented antiperspirant – it’ll take care of both.
