Ok so here are a few things, are you setting your foundation before you apply liner to the bottom (powder) - are you setting your liner with a simmilarly colored eye shadow as well? You are probably using an oil based make up remover as well w/out getting it off properly (use toner after oil based products) and you should see a difference after setting with powder. If you are already doing these things you should try using products that are not "creamy" so if you are using a creamy foundation try a mousse or matte product and if you are using a creamy liner try a penci liner. In addition are you applying primer on your entire lid and lower lid before doing your eye make up? It could also be your mascara causing part of the problem, do you bat your lashes a lot or wear mascara on the bottom lashes, sometimes the 'thicker' mascara should only be on the top and the lighter defining on the bottom if you must put it on your lower lashes it can cause issues in that area too.
