I know I'm late to this one but I finally caved and bought the Charlotte Tilbury Airbrush Setting Spray! I've been using Urban Decay for years and never really liked it as it makes my skin feel very dry and uncomfortable, and my alternative Glo Skin Beauty has stopped selling in the UK. The CT spray is SO GOOD, it feels like you've got nothing on and sets make up so well! I didn't even have to touch up my powder, there's no reaction to my makeup, it just looks flawless. If anyone else has been settling for the Urban Decay and doesn't like it, I'd definitely recommend going for the CT instead!
