"Do you need a mask for your butt? Probably not. Did I enjoy using the Bawdy x Sephora Collection Butt Sheet Mask ($8)? More than many of my go-to face masks. I slapped it on and laid on my bed without pants for 15 minutes. It didn't 'firm and plump' my bottom (like the brand claimed) as much as a squat workout would, but my skin felt incredible. It was smooth and, not that anyone is really taking that close of a look, seemed brighter in tone." — JMC
