Are deodorants bad for my skin?
Deodorants are only bad for your skin if you happen to be sensitized or irritated by them. If the skin gets itchy or red then you're using it too often. Some people can only tolerate deodorant under the arm every second or third night, otherwise they get irritated, so it depends on your skin sensitivity. They're not dangerous for you, although there is this debate about certain ingredients and breast cancer in women. It's not proven, but that's an ongoing discussion.
