Smile before applying. This is to stretch the lips a little so that, while applying the lipstick, it won’t drag. It also helps to get color into every nook and cranny.
If you are using lipstick in a tub, consider using a lip brush for the precise placement of color. If you do not have brush, try using your smallest finger. It does get the job done but it’s a bit messy, so wipe your hands right after.
If your lips are flaky, exfoliate first with a lip scrub, or a facial exfoliate, or even brown sugar. Then smooth on a lip cream or balm before applying the lipstick.
If your lips are always dry, choose a more hydrating formula, like a cream lipstick or a tinted balm.
Stains can take some getting used to. I recommend applying them from the inside of your lips out towards the perimeter so that you can avoid obvious mistakes around the lip line. If you want extra shine, allow a stain to set for a minute, then top with gloss.
Before walking out the door, regardless of the formula you’re wearing, stick your pointer finger in your mouth and drag it out slowly to capture any excess lipstick. Then it won’t end up on your teeth!
I don’t believe in rules to apply lipstick. Some women use lipstick brushes. Others use their middle finger. Most people apply it right from the tube. Choose the way that’s right for you; as long as the color gets on the lips, you’re good.
