I have smelly under arm pits and no matter what kind of deodorant I use it still doesn't work.

You can look into getting Botox injection in your armpit area, which minimizes underarm sweating and therefore it minimizes the odor. The hair is the main cause of the odor. It intensifies the smell, so you may want consider removing your armpit hair if you are not doing it already. If your hair grows at fast pace, you may consider laser hair removal too. Good luck!

Botox def works but also research Precision Tx as a permanent treatment. It is a one time treatment.
