I have covered tightlining briefly before but here is a more detailed entry with step-by-step pictures so you can really see the difference.
Before and After
What Is Tightlining?
Tightlining is a more advanced lining technique commonly used to make the eyelashes appear fuller. It is usually done along the top lash line where the liner is being “pushed” into the lash line. It is also known as “invisible liner” in Asia.
What You Will Need
* Push Brush with Gel Eyeliner/Cake Liner. My picks are MAC 212 Flat Definer and MAC Fluidline.
* Pencil Eyeliner. A waterproof one is highly recommended to avoid smearing.
* Liquid Eyeliner. I like to use one with a felt-tip applicator like MAC Penultimate Eye Liner.
How To Tightline Your Eyes
Step 1: Gently lift up your eyelid and run a pencil between the roots of your lashes to fill in the tiny gaps between them. Make sure the tip of your pencil is soft enough and be careful not to poke yourself in the eye.
Step 2: Follow with a liquid liner so the line stays on better. You can also just use a liquid liner by itself.
With a gel liner, you dip a flat brush into the product and gently push the liner into the lash line from beneath the lashes.
Use a Q-tip to clean up smudges and make sure there are no spaces between the liner and your lashes.
