To achieve a soft smoky eye, go for pencil eyeliner as it tends to be softer and creamier.
Use a makeup remover so that your eyelids are oil/grease-free to ensure a smudge-proof application with the eyeliner.
To get that perfect wing while using an eyeliner, keep your eyes open, look straight into the mirror, and line the outer corners of the eyes.
Make sure you apply the eyeliner as close to the lash line as possible so that it appears to be bba part of your natural lashline.
As you age, you might be reluctant to use an eyeliner. You don’t have to stop using the eyeliner, rather, opt for more subtle colors, such as brown and grey, and apply lots of mascara to complement the look.
