THE BEST PRIMER/SETTING SPRAY I'VE EVER USED. I can go on about this product for days. Compared to the Smashbox Primer Water (which I also love), you get 3.4 FL OZ with the full size MAC bottle for $23, the Smashbox bottle has 3.9 FL OZ but it's almost double the price at $39 and the MAC spray works WAY BETTER. It is worth every penny and to me it doesn't run out quickly. The product itself is very refreshing and gives my makeup an amazing look. I have oily skin so I use a lot of powder over my foundation and after using this spray I don't look cakey at all, it doesn't make my skin any oilier either. I use it before and after applying my makeup and my complexion looks perfect. I also mist this onto my skin on days where I'm not wearing makeup because it's so refreshing and gives me a nice hydrated look. The smell is also to die for, I really hope they make a perfume or lotion that smells like this because it smells really good. If you've never tried this setting spray, go and get a travel sized bottle and test it out or try it on in the store. I promise you'll love it.
