Calling the day wearing this before bedtime is a wise decision, especially if you've been all day out wearing make up and confronting a polluted area like most big cities are. It's calming and refreshing. If you happen to have a sensitive yet oily skin, this is your go to sleeping mask. I've tried Lioele waterdrop sleeping pack before, it was okay but, for my skin at least, this mask by a'pieu is much better and actually calming if you're prone to catching allergies or feeling your skin irritated
