Make younger looking eyes and no other makeup for a fresh-faced look.
I found that Lighter colors and white makes your eyes look younger! If you want, you can put some lighter concealer under your eyes to cover dark circles.
Bright Turquoise looks great with darker eyes and white in the corners give eyes a sparkling, dewey look. Then white on browbone and blend! Viola! It looks a bit dark here, darn webcam!
