When my skin is looking dull and could do with an injection of life, these are the products I turn to. First of all you want to moisturise your skin well before you apply any makeup. A good moisturised base will stop your foundation from looking overly cake and clinging to any dry patches. Then you want to take a foundation with a good glow factor. In this case think Rimmel Match Perfection Foundation. Just the right amount of glow, no disco ball shine in sight! I often like to mix this with something like the SEVENTEEN Skin Wow 3 Way Highlighter to add even more of a glow. This product can also be used on any high points of the face to accentuate them and bring them forward.  If you are looking for more of a full on cheekbone highlight with a real shimmer, then something like the MUA Undress Your Skin Highlighting Powder would do. To brighten your under eyes take a concealer ( I like MAC Prolongwear concealer in NC15) in a shade slightly lighter than your skin tone in order to add 'light and luminosity' to the area. Finally to add a pop of colour to the cheeks and give you that fresh faced look, use a cream blush & bronzer. These tend to be more dewy than their standard powder sisters and can make your face look really healthy. I like the ELF Contouring Blush and Bronzer Cream in 'St Lucia' as it is really affordable and is a really lovely product after getting used to the sometimes tricky application!
