Yes, but as an adult you're deliberately putting it on pores that aren't exposed to the elements nearly as often as your hands are. Also, most adults don't make mudpies anymore - it usually stops around 8 years old or so, lasting only a few years, since you didn't likely begin till you were 3 or 4.
I don't use antiperspirant because of the aluminum and your body sweats to release toxins. Ok, some of us sweat more than others, and you gotta do whatcha gotta do. I understand this. But I also research the hell out of my choices and make the best decision for me and my family.
