8. Avoid Black Eyeliner
There are three rules to using eyeliner. First, choose a less dramatic color like brown instead of black. Brown will look more natural and will help ease the transition between skin and a dark mascara.
The second rule to eyeliner is to never apply it in hard lines. Go for a diffuse, soft, blended color. Smudging the edge of the line farthest from the lashes with a Q-tip will help create a natural look.
Finally, never apply liner to the lower lid. This will only serve to emphasize wrinkles and make the eye look smaller.
