Hey there. I read about Odaban a few times and I researched it but I never bought it because I'm scared to get aluminum poisoning and other stuff from the heavy aluminum. It says its safe to use in intimate areas. I tried crystal body deodorant there with potassium alum not aluminum chloride and i actually had a headache at the end of the day and pain and it didnt work. At this point tho i just tried everything and i bought this one anyway. Ill let you guys know how it goes.
