Yeah Josy is bordering Ariana Grande levels of black face, she even bought a pair of platinum grills....If anyone was thought to be "tanning a lot" by the later episodes, I'd look more towards Josy and Bella. I've already talked about how Bella's skintone can wildly fluctuate, with the Season 3 main menu image being the most egregious example, but Josy sometimes looks a little more "sun-kissed" than usual.
But again, the lighting.
