I have probably used the same brand of antiperspirant / deodorant since High School. There is probably nothing wrong with continuing to use it. But I've been reading a lot about how I should be avoiding Aluminum & Paraben, so I went looking for something without it. All the antiperspirants had aluminum so I was gonna just get deodorant. Then I found Herbal Clear naturally. Aluminum, Paraben & Alcohol Free and Hypoallergenic. http://www.21stcenturyvitamins.com
So far so good. It feels nice and doesn't really smell.
