It seems to have appeared over the last 3/4 weeks and looks just like I've been reading a newspaper and rubbed my finger across my top lip! I've looked in all kinds of light and it's definitely not hairs as those are fine & blonde in that area, but what else can it be?
It seems slightly more noticeable when I'm wearing face powder or foundation, but it's the same stuff I've used for years so don't think it's a reaction or the wrong shade?
