Tools you will need:
-One thin, pin-point brush
-One thin, angled brush
-Concealer that matches your skin tone
-A black eyeshadow
-A liquid eyeliner
Helpful hint: Instead of spending $20 on an eyeliner, you can get one, like the e.l.f. liquid liner, that's much cheaper.
First, you want to sketch out the eyeliner with a black eyeshadow, using an angled detailer brush. The eyeshadow will be more forgiving if you make any mistakes. You can also clean up anything with some concealer if needed.
Once it is looking how you want it, dip your detailer brush into the liquid eyeliner formula and trace over the black eyeshadow. You can smoke the liner out with more eyeshadow or clean it up with some concealer.
