I've always wondered what is that white thing on juries face?

For years I thought it was dough or something that got on her face because of how frantic the situation was and I smiled to myself at jurie having white liquid splashed on her face...

Looking closer it looks like a bandaid or something. If so why does she have it? Nothing in the situation says anything about it

Also, total side note but there is something really weirdly sexy about Odell's revealing her hands like that. No idea why
