I was using MAC Prep + Prime Skin Refined Zone Treatment but I have been switching over to all vegan products. This is also cheaper - $16 for 15 ml versus $21 for 15 ml. It's not quite as good as MAC but pretty close. I'm happy with it and will keep using it.
This is my favorite setting powder ever! It's super fine, so it goes on even more sheer than it looks and it helps keep my skin from getting shiny through the day. You only need a little and it lasts forever. I actually use this over a powder foundation and it kind of fills in the texture.
