The problem with eyeliner tightlining

Have you ever tightlined your eyes thinking your eyeliner will look on point? Well, think again...

Tightlining is an eyeliner application technique where you apply the eyeliner to the base of the eyelashes on the rim of the eyelid instead of lining the skin above the eyelashes.

It's done because it's an easy makeup trick that makes the eyelashes look longer and fuller.⁠

The tightlining makeup technique might temporarily look good but it’s not so great for your lashes, and here's why!⁠

So here's the issue -- when you apply eyeliner directly to the rim of the eyelid, you've clogged the lash line oil glands with the eyeliner.

When the lash line oil glands become clogged, they get inflamed and this affects the growth of your eyelashes.
