How deodorant works
If you don’t know how traditional antiperspirants work, let me give you the low down: little pieces of aluminum plug up your armpit holes to stop you from sweating. It’s like a bunch of tiny, powder-fresh aluminum tampons for your funk holes.
Deodorant, on the other hand, doesn’t stop you from sweating but it makes your sweat smell like cucumber melon. Most stuff on the market is antiperspirant, but I use the two interchangeably (because I am lazy).
