I headed to the MAC counter and ended up with MAC Pressed Blot Powder. It costs £17 so isn't particularly cheap. The packaging is simple and the powder itself is very fine. The girl at the counter explained that the colour choice isn't too important and as it's so light and see through. I'm pale and was recommended the medium which I was a little dubious about but it turns out I have no problems with it. Also available is light, medium/dark, dark and deep dark.
According to the MAC website this powder is A unique pressed powder designed primarily to provide shine control without adding any noticeable colour or texture. Sets foundation, finishes faces. For use in professional situations and for frequent touch-ups. Blot Powder contains Mica and Silica to adsorb excess oils and reduce shine on the skin's surface. Can be applied with the puff that comes in the compact or with a powder brush like #129 Powder/Blush Brush. Perfect for touching up Studio Fix Powder Plus Foundation throughout the day.
So far I have used with a large brush to set my make up and bring the compact with powder puff to blot with.
All in all I love it!
My one little gripe is I'm not sure how long it will last so I'm trying to restrict myself to only using it to blot on nights out.
Have you tried it or do you have any recommendations for something else cheaper? I don't think I'll ditch my cheapie blotting paper for it but I'm always on the look out for a cheaper matte setting powder alternative...
