Will Lush fresh face masks last over the expiration date? My answer, YES! I've had my BB Seaweed mask for over a month from the expiration date. I use it pretty much every week and I'm down to my last two masks from it. It smells the same that it did when I got it and it doesn't seem to have mold on it. I don't know how much longer it would last, since I'm using the last part of it this week. But, I would say as long as it still smells good and you don't notice any weird things growing out of it, you should be good to go! Let me know what your experience with the fresh face masks have been like!
