I'm not sure if I'm reading you right, but if I am, you are saying that it takes a long time to kick in. Therefore I need to give up bathing while I wait for it to kick in. Therefore I would need to give up swimming because it's not useful if I want to replace the good bacteria lost from swimming in a chlorinated pool and then showering off the chlorine.
I did read one article (after I posted) where the reporter skipped showering for a month then took one shower and washed it all away (according to the bacterial swabs he took).
I still do not know what do you want to do. What is the goal you're trying to achieve by using that thing?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
