I noticed that this summer I did not have that usual annoying sweating right above my upper lip and my face kept drier in general.
I use baking soda as deodorant, but even if I forget I smell good :)
I also noticed that my tops keep smelling fresh and if I wanted I could wear them several days in a row. I tried it with my tops I wear at night. Three days and they still smell fresh - havent tried longer.
