It's not an antiperspirant but I recommend this deodorant: https://www.amazon.co.uk/PitRok-W1060-Push-Up-Crystal-Deodorant/dp/B000S858L0/ref=sr_1_1_a_it?ie=UTF8&qid=1507489012&sr=8-1&keywords=pitrok+deodorant
It's very good for sensitive skin and lasts a long time. One stick will last more than a year.
Pitrok. Lasts forever, little to no sweat, no sweat smells. Seems expensive but the little stick lasts nearly 6 months (literally).
