got this because my makeup tends to become splotchy and cakey by the end of 12 hr shift so I wanted something which could keep my makeup looking fresh and good all day. There are two ways to use this product either use this on top as a setting spray or use this directly on the face as a primer. I personally prefer the first method. I have noticed that this does helps a lot . Ever since I have started using this my makeup looks a lot better and the sebum does not mess my makeup
