I saw another review that said the Canadian version doesn't have SPF, but I can honestly verify that it says SPF20 broad spectrum right on the tube and bold letters that read "made in Canada" on the back. With that out of the way, I think this product is better than many primers and moisturizers out there! It's like a sunscreen sort of thick consistency, but absorbs nicely and feels very lightweight. The struggle I face is actually finding a good base for Mac's face and body foundation; the finish is too shiny for me. This tones it down just enough but still leaves a bit of glow. The smoothness of my foundation is something you wouldn't believe, making this combo a HG for me. My foundation looks flawless! I've ditched my laura mercier primer, and I've also ditched my face lotion because this product does both! I love everything about it, and it's a staple in my collection from now on.
Edit: I still have to blot every 2 hours in the heat, but if I'm in AC all day, 8 hours control is no problem. I've tried double layering it, but it starts rolling off. I also find that this doesn't work well with other priming products, mainly the MUFE mattifying primer and Laura Mercier oil-free primer (things starts rolling off). Still.. I like the consistency and the included SPF, but it kind of forces you to rely solely on it.
