Matte eyeshadows are quite tricky to use because of its flat finish.
It is best to use them to contour your eyes (and even the face if you use the right color)
because its finish mimics the texture of your skin thus making the contour natural.
Of course, you can use a matte eyeshadow all over your eyes,
but make sure to curl your lashes and put on mascara to give your eyes more life
and avoid looking flat.
If you find yourself having a hard time blending matte eyeshadows,
very lightly dust your eyelids with loose powder prior to eyeshadow application.
This removes the natural oils on your lids to make them smooth and ready for eye makeup.
