I stumbled upon this very innocently--it was a hot day, we were heading out with some friends and I popped into the drugstore to buy some sunscreen on our way out. That was October 08. I have used it every morning since then. The bottle lasts forever. It is super lightweight and good everyday ss. It is a little white when you first put it on, but is so lightweight that you can just blend it right in. I don't feel a trace of it once it is on and use it alone and with makeup on top. I can't believe the value. I have tried expensive ss from Barneys & this is much better. It doesn't always have to be pricey to be the best!
