Always soften out any edges you make with colors. The most common flaw girls do is to leave the edges of the eye shadow, blush and foundation with a sharp line. This will draw attention and will also give an appearance of something being false or too much.
MAKEUP TIP # 9
Use a shiny eye shadow without glitter in a tone lighter than your own skin tone over cheek bones, along the nose bone, just over the lip on the cupids bow and in the inner corners of your eyes to always get that healthy and fresh look to any makeup.
