If you have standard, oval eyes like Hayden Panettiere:
How to use it: You can work your magic with this eye-widening trick: Starting from the inner corner of your eye, draw a thin line of eyeliner that gets thicker towards the middle of the eye and back to thin once you reach the outer corner. Works like a charm.
What NOT to do: Use liner on your lower lashes. If your oval eyes are on the smaller side, skip the lower liner. Just curl your lashes and apply at least two coats of mascara.
