Antiperspirant rash
- skin condition occurring after occasional antiperspirant use, commonly diagnosed as contact dermatitis (see in Antiperspirants and deodorants). In our experiments ceased to happen in the absence of bad armpit odor.
Apparently antiperspirant rash reflects dramatic changes in underarm community. We have no idea what exactly going on, but, clearly, once you get all those guys on your skin, you have to feed them, or kill them. Antiperspirant destroys their habitat. They struggle for life, etc. It is unusual, cruel and ineffective technology.
Seems like antiperspirant rash also reveals infection and maps it in a way Wood's lamp does. Unfortunately, there are not so many people prone to it. It may serve as an important diagnostic tool otherwise.
