This is why I prefer Bobbi Brown foundations (both stick and liquid) they don’t make my face appear grey/ashen. MAC has a tendency to make your face look dull after a while. Makeup/concealing creams can never match the natural skin and complexion.
For the eyes, an eye-primer and overall base color will make a huge difference. CB, pat-on a highlighter to the apples of your cheeks after you apply your blush. It’s a ‘pick-me-upper’ for tired and dull looking skin.
