Anti-redness primer

[Timefortea99]

Just saw a Marion Keyes blog thingy about make up. She said she gets red chinitis - as do I specially during colder months. She uses a blue primer from Make Up Forever but it is 25 quid. I want to try one. The Smasbox green one gets good reviews but that is £20. Any recommendations for a cheaper one?

I have rosacea and used a thin layer of Boots no7 which was quite good. However, I have now moved on to using a benefit concealer in a tin and that lasts all day and is more effective
