Shockingly works
I've tried Sweat Block, Certain Dri, Mitchum, and nothing really made a difference. I tend to sweat irrespective of temperature and have been severely limited in clothing choices as a result. I tried this the first week and was not impressed. By week two however this made a huge difference and has been working ever since. It's not impossible to sweat, but whereas before I'd be pitting out all day, there's nothing now and I can confidently wear shirts I was reluctant to wear before. I use deodorant (not anti-perspirant) every day in addition to the weekly use of this. I cannot recommend highly enough, better than anything else I have ever tried.
