I had never heard of (let alone used) a setting spray before I bought this on a whim a few months back. I honestly doubted it would do much at all, as I dont use much actual make-up. I use a glowtion and a little bronzer which gives a nice amount of glow, but fails to last all day and would rub off on fabrics. Well, since using this, that has changed! I dont always remember to use daily; and I can tell when I dont. The matte finish is actually perfect against the more shiny look; evens it into that perfect glow where it will stay most of the day. Super quick and doesnt have a scent that I notice. For use I close eyes (and mouth of course), shake bottle, hold about 10-12 from my face & give it a few quick sprays to cover my face, (you dont need much at all), open eyes, fam with my hands for a few seconds to dry and set quickly. Done!! Leaves beautiful looking skin which doesnt look like I wear a lot of makeup, (good because I dont!), just fresh & glowy skin that lasts. I love this product and will buy more as needed. (It lasts forever which is excellent too!!)
