tips on pencil eyeliner lasting?

ive been waterlining and tightling my eyes for a while now and ive found a problem that really irks me.

my eyeliner keeps spilling and all ends up in the corner of my eye in a droop and none lasting on my waterline.

i know my eyeliner isnt necessarily good ( a regular technic pencil eyeliner ) but i was wondering if theres anything to make it last a bit longer and not smudge as much atleast?

i saw somewhere ( probably a tiktok ) that you can set it with setting powder and apply more on top to keep it in place. now this kinda worked since there was still some eyeliner left on my actual waterline and not in the corner of my eye but it still smudged quite a bit, and it irritated my eye sometimes if i accidentally use too much powder.

obviously i know one of the main things would be to get a different, preferably waterproof, pencil eyeliner but i have no idea what good waterproof pencil eyeliners there are. i havent really seen many eyeliner * pencils * recently anyway.

if anyone has any suggestions and / or tips they would be greatly appreciated !!
