When looking at my concealer collection, I decided, consistency-wise, a cream concealer would be best because a matte, oil-free texture sounded longer lasting than something liquid. Plus, it felt more sanitary to use my finger to apply my Nars matte concealer, as it was easier to scoop out the amount I needed vs. a concealer with an applicator wand. Of course, I'd still recommend cleaning it first and not "double-dipping" a finger back in once you've applied the concealer on your lips, especially if you're a bit of a germaphobe like me.
After that step, I finished getting ready so my lips would be as dry as possible before the next step.
