Powder... you should wear the same color as your skin tone or lighter this should be worn over cream, liquid, or primer. If you want a more everyday. look you can apply just in the T zone (that includes forehead, cheeks, and chin)
LIQUID
Using a beauty blender makes it so much easier to blend without brush strokes. When using this kind of foundation
It's important to blend around your neck so you do not look like you're wearing a mask. To much of this will not look nice so add as a dab to the back of your hand then blend.
