if you're willing to dish out the dough for it, get it!
or if you have the dough to be dished out, get la mer. have you checked dept. stores like the bay and sears? they're kinda low end but they do have brands like Dior, la prairie, etc on the cosmetics floor. or if you dont have dough, you should try shiseido

I'm pretty sure only Holt Renfrew carries La Prairie in Canada. Imo, I've used the stuff (Caviar and Radiance collections) and I do find it is more geared towards the older crowd. Honestly, I don't really find it as beneficial at such a young age, but maybe others do. As she ^ said, if you've got the money, then why not?!

Were there any specific products that you were looking at?
