How do I apply my foundation

Use your fingers to apply foundation if you want sheer coverage and a brush if you more polished, medium to full coverage.
How to contour my face

Contouring seems like a difficult task if you have never done it however it is easier than you think. Imagine a light over your head. The areas of the face that light will illuminate and those are areas you highlight. The areas that have shadows are contours.

Finding the right product is easy and you could even use a foundation or concealer in a darker shade than your skin tone or a bronzer as a contour and a foundation or concealer lighter than your skin tone as a highlighter.
