I've been using Diorskin Forever foundation for ages now, but recently its stopped working for me. I have no idea why, but it used to make my skin look all radiant and glowy, and now it just makes it look dull and chalky.
So I've narrowed it down to: Charlotte Tilbury Magic, Tom Ford Traceless Perfecting, and YSL Touche Éclat.
Any recommendations would be great. I'm extremely pale, have fairly decent skin that's not particularly dry nor oily, and like decent coverage that's not too heavy looking.
