If you want your makeup to look like "skin"
I use this to set my makeup. This is much cheaper than Scindinavia, and works just as well if not better. Sometimes I go a little crazy with makeup, ya know, layers of foundation, concealer, blush, bronzer, contouring, and then I like to powder bake to make my lines go away. At the end,  there are so many layers that look great on camera, but in real life- everyone can tell you have makeup on. So I spray this 4-10 times all over, and it doesn't erase the work I've done on my face- it just makes it stick to my skin (don't worry it doesn't FEEL sticky). It also gives me a glow from within despite all the layers I have, so it really makes it seem like I have great glowy skin. I can't live without this product now, and it's going to be in my makeup arsenal forever (or until the obviously powdered face becomes a style).
