This is like a secret that unbelievably hasn’t hit the mainstream. If you sweat heavily pretty much no antiperspirant will work as advertised. Some of the prescription brands have you applying the night before and I had some success but they tended to tear up my armpits and ultimately fail. Personally I see a direct correlation between alcohol consumption and sweating. I discovered that as an unintended consequence during a 30 day detox. If I limit my alcohol intake and use just a deodorant I find myself much better off. Worth experimenting with if you’ve tried everything else.

At least from my attempts / for me: antiperspirant is dramatically more effective, for far longer, at preventing body odor. Like 4 hours (or less) vs 24+ hours better.
