This deodorant by Thai Deodorant Stone is amazing and as soon as I tried it became my new favorite. First of all, it is completely natural and it doesn't have any alcohol. Alcohol usually irritates my skin, so that is the ingredient I try to avoid most. Also, it doesn't contain aluminum chlorhydrates, an ingredient that has been connected to cancer. This also doesn't have any scent and it doesn't leave any white cast either. The deodorant is very watery, and it basically feels like water on the skin, too. Very convenient to use and this is perfect for a sensitive skin. A very safe choice.
You can get it from iherb. The price is very reasonable, $3.83.
