What is a good anti-perspirant?
I have been using Secret Invisible Solid for years, but all of the sudden it only works for a few hours and I am damp. I tried switching to Degree clear solid and it is worse and the deodorant in it doesn't work at all.
I have to wear a black shirt as my work uniform, so I need something that won't leave white marks, but what is strong enough? I don't want to spend hundreds of dollars to test every product, so I thought I would get your opinions!
