LIPSTICK

Most lipstick consists of a fatty base, to ensure that the product stays firm and solid but is easily spread over the lips, and colour provided by pigments or dyes. Manufacturers put a lot of time, effort and money into making sure that their products are soft enough to cover the lips smoothly and with the minimum of pressure, do not fade too quickly and stay put while the owner of the lips does other things like eating, drinking, smoking or kissing. Manufacturers also test lipsticks for toxicity, since the product is often swallowed. If you suffer from dry, sore or chapped lips, use an ordinary moisturizer before you put lipstick on.
