Wow, the tube is very large and should last at least 60 days, even using it twice daily. I love the WL defining moment serum. I ran out for about 4 weeks and really recognized a difference. Now I'm on auto-ship. I prefer this new tube container, it's easier to store in comparison to the pump container. I'm turning 38 this year and I have always taken care of my skin, however, this kicks it up a few notches. Thanks Wei!
