Here is a mind blowing tutorial on doing like a professional makeup artist. This expert has broken down her makeup in to small easy to follow steps you can easily learn what goes into creating those flawless eyes. As with any eye makeup, it is necessary to start with a primer and then apply a base eye shadow like MAC offers one with the name Pro Longwear Paint. This base color should be in a neutral shade.
The first step is to define the crease of your eye. It is up to you if you want to do it with an eye liner pencil or a fine tipped eye shadow brush. When you draw a perfect V shape starting from the middle of the eyelid and ending at the outer corner of your eye, the end result will be flawless.
Then take your pencil or brush towards the inner corner of your eyes beginning from the middle of the crease because your purpose is to define full crease on the entire eyelid. Avoid pressure as you move towards the inner corner of your eyes because we want a delicate and less noticeable line on that spot.
Now blur out the line and add some color. You can apply whatever shade you like. This shade should cover the top of this crease and slightly overshadow it too. You can highlight the brow bone if you want to perk it up. Add more flair with winged eye liner and finish it off with mascara.
