Okay so I suck and I mean suck at liquid eyeliner, I blink I wince and go wayyyyy to thick.
So this trick has saved me sooooooo much.
It gives me that smooth edge I desire from liquid but its as basic as using the pencil.
Get and sharp eyeliner, who cares what colour go crazy.
1 second under any flame - be safe
Let it cool for 15 seconds
