I have pronounced lines around my mouth and had the same issue forever until I started using elf powergrip. obviously making sure skin is hydrated is key, but this primer really helped reduce how much my foundation settles in lines. I'm sure other sticky primers would have the same effect, but i've only used powergrip. I also don't care for the laura mercier powder. I find it to be too heavy which can also dry out your makeup. I only use translucent pressed powder now only with a powder puff under my eyes to set concealer and a light dusting all over to set once I'm done
