I?m a nurse , Do you think it would last during a 12hr shift in the heat/sweat without smudging ?

It is great. I put on my Dior primer then Buxom waterproof mascara at 630 am out the door by 7 am and return home at 10pm from work everyday. I never do any touch ups and my eyes look great. Well my lashes do anyway. My eyes are red and bloodshot but the lashes look like they did at 7 am.
