Lipstick is one of the last things that you do in your makeup routine, via L'Oreal Paris USA. But before you walk away from your mirror, make sure that lipstick stays on your lips and doesn't end up on your teeth. Here's how. Right after you finish putting on your lipstick, put your index finger into your mouth, close your lips, and pull the finger back out. Ta-da! The lipstick that could have most easily ended up on your teeth is now on your finger, as noted by Byrdie.
There's another step you can take before the index finger trick to help keep your teeth free from any errant lip color. Makeup artist Melissa Van Dijk recommends using your index fingers to wipe the corners of your lips from the outside in, which helps keep lipstick off your teeth and from smudging, via YouTube. You can also blot your lips on a tissue before doing the index finger trick as an additional way to remove excess product, per Cosmopolitan. Use a light touch with the blotting so you don't ruin all the work you just put into doing your lips.
