1.) Angled Brush (or any brush you're comfortable lining the inner lid with)
2.) Matte black eyeshadow (or dark brown if you prefer your mascara to be brown), black/brown gel eyeliner or black/brown eye kohl pencil.
Step 1: Grab some of your matte eyeshadow, kohl pencil or gel eyeliner. (I'm using UD Blackout matte black eyeshadow in the Naked 2 Palette.)
Step 2: PUSH it on the top inside of your lash line (shown above).
I realize that this picture looks freaky because of my green contacts not being aligned w/ my real eyes but this is the only good picture I had! haha! sorry! Don't worry! it doesn't hurt at all! For beginners/individuals with sensitive eyes use small strokes to line the inner lids.
One eye tightlined: notice the right side appearing to be a bit more fuller than the left side.
w/ both eyes tightlined
I hope this technique is useful to you! Do you have any tips/tricks in tightlining? Let me know! :)
Until Next Time!
