Prep: You always want to prep your eyes first! Even if you're going without eyeshadow, applying a primer will even out your skin tone and fill in any wrinkles, which detract from your gorgeous lookers. I use Younique's Glorious. It's 100% natural, gluten-free, free of parabens, oils, synthetic fragrances, and cheap fillers so a little goes a long way.
Extension: Extend the eyeliner beyond the outer corners of your eyes. This line should move upwards a little as well, mimicking a very long eyelash. This technique will make your eyes appear wider.
White: Add white eyeshadow or eyeliner to the inner corner of your eyes. This technique helps to bring more light into your eyes and produces the effect of larger-looking eyes. Use soft white though; a harsh white will look theatrical.
Eyebrows: In much the same way a picture frame affects the way the picture looks, your eyebrows affect the way your eyes look. The simple act of removing stray hairs can make your eyes more noticeable.
Eyelashes: You want to make your eyelashes longer. A good way to go about this is a eyelash curler. I, personally, am still deathly afraid of them and prefer to use Fiber Lashes. It's a two bottle mascara system that uses the natural fibers from tea to extend your lashes & add great volume, while still looking natural.
Bags: You definitely want to get rid of dark circles and bags as the puffiness makes your eyes seem smaller. The easiest way for me to do this is to splash a little rose water around my eyes in the morning. Other good ways are applying slices of raw potato or chilled tea bags for 20 minutes.
Enjoy your big, beautiful eyes!
