Do you use Vaseline on your lips to moisturise them? I would definitely do that if you struggle with chapped lips. My lipstick routine is: lipliner (if I have any in the right colour), first coat, blot with a piece of toilet/tissue paper, second coat, mayyybe some vaseline/gloss on top but usually just stick with the lipstick as gloss is when things tend to get messy. the lipliner tends to stop it smudging and the blotting/second coat helps it to stay (even when most of it’s faded, you usually still have a tint left). but yeah, if I eat then I tend to accept its fate and just rub it all off with a napkin.
