The most difficult thing for me was to find a deodorant that worked for my armpits; I did a lot of chlorella for a year or two, that helped quite a lot.
Now I either use vitamin c straight on my armpit, let it dry and then put some oil with fragrance on top.
-or I use one mineral type of deodorant I found at a health shop. More convenient.
the vitamin C really works; I just have to be sure that I dont spill any; then I get stains on my clothes.
