The decision to apply eyeliner on top, the bottom, or both depends on your preference and the look you want to achieve.

Some General Guidelines

Applying Eyeliner on the Top Lash Line for Large-looking Eyes

This is a classic look that can enhance the natural shape of your eyes and make them appear larger. It can also be a good option if you have small or close-set eyes, as applying eyeliner on the bottom lash line can make them look even smaller.

Applying Eyeliner On the Bottom Lash Line Only

This creates a more dramatic and edgy look, especially if you use a bold colour or want smudged eyes.

Applying Eyeliner on Both Top and Bottom Lash Lines

This can create a more defined and balanced look, especially if you use a thin or medium-sized line. However, if you have very small or deep-set eyes, applying eyeliner on both lash lines can make them appear even smaller.

In general, it’s best to start with a thin line and gradually build up the thickness or intensity as needed. You can also experiment with different colours, textures and techniques to find the look that suits you.
