Deodorants work by making your armpit unfavorable to sweat-eating bacteria by turning your skin acidic (that's what stick deodorants do) or salty (that's what natural crystal or "rock" deodorants do)
Dove... I forget which one specifically, but it's white with a see-through light green cap... and it usually comes in a two pack. It smells soo good and lasts the whole day. :)
I like the Dove- Clinical Protection. A bit pricey, but totally works.
Thank you :) will try it out! x
