Summarize the following:
A good way to see what you're up against is to plant a firm smooch on the back of your own hand. If some of the lipstick transfers to your hand, it's a good sign that you'll be able to deal with the rest of it without a lot of hassle. If you're still wearing a thick, dark coat after the kiss test, you probably have your work cut out for you.  Long-lasting lip colors are resistant to smears and smudges and in most cases will have to be removed through other means.  Don't forget to wash your hands afterwards so you don't accidentally leave stains on anything else. Take a washcloth or durable paper towel and blot at your lips. Use a light swirling motion to break up the lip stain. Go over your mouth a few times until the washcloth or paper towel stops collecting color. The more lipstick you can strip off beforehand, the easier it will be to get rid of the rest. If the lipstick you're wearing is particularly stubborn, you might need to give your lips a preliminary cleaning before you can remove the bulk of it. Wet a clean washcloth and lather it up with warm water gentle hand soap. Dab your lips with the corner of the washcloth, then rinse. When combined with the heat of the water, the surfactants in the soap should start to wear down the lipstick.  Choose a soap that is non-drying and suitable for facial use. Most liquid hand soaps and body washes will work just fine. Avoid soaps with harsh fragrances, as these normally contain chemicals that can cause rashes and allergic reactions. You may also have success using facial cleansers that contain gritty exfoliants. Rub a thick layer of moisturizing chapstick or lip balm onto both lips. The moisturizing agents will saturate and plump up your lip tissue, forcing more of the lipstick to the surface and making it easier to wipe away. It will also keep them soft and protected from dryness and damage.  Don't be afraid to get heavy-handed with the lip balm prior to removing your lipstick. More is better. Use an old chapstick that you're not worried about ruining with your lipstick shade.
Kiss your hand. Wipe off as much as you can. Wash with soap and water. Apply a coat of lip balm.
