Is mineral stone safe alternative?

DEAR DR. GOTT: This is in response to the writer looking for a safe deodorant.

After years of using and changing deodorants because they failed, I found the mineral stone. I’ve used it for more than 10 years. I apply it daily after a bath and have never had an odor problem since. I’m thoroughly satisfied and it’s perfectly safe to use.

DEAR READER: I’ve been waiting for readers to recommend a safe and effective product to reduce perspiration odor. The stone may be a breakthrough. Let me know of your experiences, readers. More later.
