There are a couple of ways to apply mascara. Although eye shadows define and dramatize your eyes, only your eyelashes are in a position to actually reflect colour into the eyes. So, to emphasize the colour of your eyes, you must frame them with an appropriate shade of mascara.
Step 1 - First look down and brush the top lashes from the roots downwards; then look up and brush the top lashes upwards. Then still looking up, brush colour on the lower lashes;
Step 2 - Wait a minute for them to dry, and similarly apply a second coat.
Step 3 - After applying the mascara, brush with a clean dry brush, to separate the lashes. You should not, however, have a lot of problem with sticking of your eye lashes if you're applying less than two coats.
