So I ordered the magnesium oil from Amazon, here is my review:
First, it was unquestionably effective in preventing underarm odor. However, there was a pronounced sting in the area I applied it. I decided to keep using it to see if the sting would diminish after a few days, but it never did. The sensation was bad enough some days that I had to wash it off to end the discomfort!
Also, it was watery and tricky to apply,so I put it in a mister bottle. Then had overspray, which was messy because the stuff is kind of sticky/oily, hard to describe. I noticed it left a residue on the floor that had to be cleaned up with a wet rag. This messy overspray also got in my mouth
somehow, and that's how I know that magnesium oil has a vile, wretched taste.
Sounded good but not something I'll be using.
