This is the first time I have ever used a setting speay. Believe it or not I had never heard of such a thing. I just never wore makeup when I was younger, but as I got older (Now 58) and because I am a Dental Hygienist, I want to look professional. l have hated having my makeup wear off on my mask all day. There sems to be mire on my mask than on me by the end of the day! This spray keeps ALL of my makeeup on me and not so much as a smudge on my mask, clear to the end of the day. When I leave to go home I look almost as good as when I arrived! I love this stuff, it is a reasonable price and I see no reason to even try any other brand. Oh, I'm also sensitive to smells and don't like to wear anything smelly because of working so close to people. I was very pleased that this had no smell.
