I developed an allergy to every stick antiperspirant I tried, after years of using them with no problem. I can be a sweaty boy from time to time, so just letting it free flow was not a professional option. I was really worried about this because I figured I'd be super allergic and need to be hospitalized, but I was that desperate to find something that worked. And I'm not allergic at all. One wipe gets me through a week easy and I've stretched it to two weeks before and been fine. 10/10, do recommend.
