Some people may be allergic, and plus, cologne won't magically make you clean. Take a long shower, and wash the armpits a ton of times, and use the deodorant 10 times on each pit.
why the forget do you think I said good hygiene?
Of course you don't use cologne to "clean" yourself. Take a shower, put this on after.
And there is the tiniest chance that someone is going to be allergic, thats just stupid
