The reviewer, nuraaden4, tried the bye panda eyes! smudge proof mascara by essence. They mentioned that the mascara claims to provide longer lashes and be smudge proof, making it suitable for those who touch their eyes frequently. In the video, nuraaden4 tested the smudge-proof claim by waiting a few seconds and then touching their lashes. While the mascara didn't fully dry, there was only a small amount of smudging. Overall, the mascara seemed to live up to its smudge-proof claim, as it didn't easily come off. However, it's worth noting that the mascara took some time to dry completely.
