1. Prime your eyes. Eye primer helps your eyeshadow last longer, the same way face primer works to keep your foundation in place. 
2. Apply a base shadow all over your lids. Sweep the shade of your choosing across the entire lid using an eyeshadow brush. Gently buff the line and blend it so that most of the product is on the lid and the least amount is on the inside, near the inner corner.
3. Apply a darker matte color on the crease. Taking a rounded blending brush, sweep it over the darker shadow, tapping off any excess, and apply it where the bone hits the crease. Brush back and forth in a half-moon shape several times for a blended contour until they blend seamlessly into your lid.
4. Apply a lighter shade as the highlight on your inner corners and brow bone. A light eyeshadow shade can moonlight as highlighter and make sunken eyes look more awake.
5. Define your lash lines in a dark color with an angled eyeliner brush. Run a slanted eyeliner brush over a dark powder shadow. If you want a more concentrated line, wet the brush before applying. Next, run the brush along the upper lash line and lower lash line to deposit color.
