Safest anti-perspirant?

[FluffiB]

I haven't been using deoderant/anti-perspirant for close to a year now. Now that the hot weather is here again, I'm dying to use some anti-perspirant. Smell is not an issue for me - sweating is. I sweat like a pig, especially my face, armpits, and my back. I can't do anything about the face or the back, but my pits need help! Skindeep website is down at the moment. Can someone recommend a product for me?
TIA!

I use the Thai deodorant crystal and I don't think it is marketed as an anti-perspirant, but it really works well and keeps me dry all day.
