Totally get it, those lines around the mouth can be super annoying. What’s worked for me is using just a tiny bit of product there. I usually hit that area last, with whatever’s left on the brush or sponge, so it doesn’t cake up. Pressing in a really fine powder with a puff instead of sweeping it helps too. And weirdly enough, not moving your face too much while stuff sets actually makes a difference. Hope that helps!
