My problem is the underarm area. I've pretty much tried those except zinc and kelp. What was weird today was that I did a little experiment and washed my underarms using Cetaphil Oil Control face wash (which contains zinc) and the BO was gone! Then I put the BP 10% solution (Epiduo face cream) and that still has yet to work.
I also had at least three cups of black tea today and a lot of water as I believe that the culprit seems to be my kidneys and liver.
To top this off, I think I should try the zinc and kelp solution, as I saw a small improvement in using the Cetaphil wash. I have yet to purchase those on Amazon though.
