HELP! Eyeliner… 

Hi guys!

I wanted to ask you all a quick question about eyeliner – is it normal that my liquid liner runs out after like 3 weeks? It’s super annoying and was wondering if there’s anyway to prevent this. I am currently using the Maybelline precise liner but it’s pretty much done and I bought it 3 weeks ago. Please recommend me great liquid liners you know of which don’t run out so quickly >< – not sure what I am doing wrong :(! Also, does anyone know how to prevent your eyeliner from smuding at the bottom corner of your eye? I always seem to have this problem.  Would much appreciate your help – thanks!
