Yep, it does. So far, even going out walking on a sweltering afternoon with a jacket on resulted in no sweating. The formulas definitely do feel different. The roll-on is drier and lighter, while the stick is creamy, thicker, and a little sticky. Both are nice, although the stick seems to be a bit more heavy-duty, and the roll-on is probably better for keeping marks off your clothes.
DeoDry doesn't promise full-on stoppage of sweat — just 24-hour odor protection. The alcohol and perlite (a volcanic glass that's known for its ability to absorb water) in it definitely keeps you dry, and the Fresh & Floral scent smells rather nice — like rose and geranium oils. So if you're looking for a good daily-use product that will keep you dry without dubious ingredients, this one gets our vote.
