It contains the discredited aluminum. But that's what makes it that a deodorant is to antiperspirant namely the fact that the sweat glands are closed. So also no toxins from the body can be excreted. Unfortunately, there are few alternatives. Whether one absolutely needs, everyone must decide for themselves.
The deodorant keeps you dry, but not completely prevent the body odor when heat is on. As you bring more fragrance which covers the whole. Whether it holds 48 hours I did not try. I took a shower in between.
Fragrance: like fresh creamed, by Nivea or other white creams, unisex
Tracks: light white marks, but only arise when sprayed directly onto dark clothing. Spray it on the skin, no residues to see. Therefore, aim well or put afterwards.
The skin is not irritating, even though I regularly shave my armpits and this thus are sensitive.
The size is easy to handle. Whether the box as long as the previous stops, I can not judge, because I've never done book about how long does a deodorant. But the can is already under considerable pressure. It may be true so that the content is compressed.
In conclusion, if not necessarily prone to sweating and wants to feel only fresh, should rather avoid for health reasons on deodorant without aluminum. Who has no problem with aluminum is prone to sweating and / or smell like, it can use well.
