i can see/feel/smell the difference when i am not using deodorant, using a normal off the shelf deodorant and the Joi deodorant. the Joi deodorant really helps to reduce my perspirant and also retains any body odour.
as for off the shelf deo, if i use it, the smell from it will mix with my glands and give off a really bad odour which then in turn sticks to my clothes and my bra and when washed, it wont rly go away. the smell will still stick and in the end i will have to throw my bra or clothes away. it actually makes the problem even worse.
hence, i rly recommend using the joi deo and will keep using it. it works best for me
