Lotion that prevents sweaty hands and feet!?

I saw this lotion advertised on the Today show once during the summer. It helps prevent hands and feet from sweating. I can't remember the name but it included a few lettes and numbers and it is not a sunscreen. Anyone know the name of the product and how to purchase it? Thanks!Lotion that prevents sweaty hands and feet!?
Look up Drysol, Aluminum Chloride 20% Apply once daily at bedtime.Lotion that prevents sweaty hands and feet!?
In addition to Drysol (which requires a prescription) try Certain Dry which is over-the-counter and is 12% aluminum chloride (drysol is 20%). The pharmacy may have an identical product offered under it's own brand as well (CVS has UltraDry). None of these are really lotions but very watery liquids that you use overnight and then wash off in the morning.
