Would anyone know why foundation sometimes seems to "sit" in the pores on my cheek bones (which honestly I can't see even when looking in a magnifying mirror) but when I use foundation - Chanel,MFA ultra HD or BobbiBrown - even when I buff it in with a real techniques brush it seems it look all "pitted". I've tried using primers (bought loads of different ones ☹) and not using them, but it doesn't seem to make any difference. Thanks
