How to get rid of red cheeks

How I manage my red cheeks

A friend recently advised me to start using blush! I could not believe it - my cheeks were always so red that using blush was only an option AFTER using a concealer of some kind. With my sensitive skin that was never very appealing. But should I really start using blush?
It's the result of using Eucerin Redness Relief to good effect for almost a year now.
