About.com has dedicated a page to body modification, including lip piercings. In the piercing section of the page, choose facial piercings and explore the Labrets and Lowbrets and Medusa/Philtrum links, which discuss specific types of lip area piercings in detail.
When considering a piercing, the location dictates the price, risks, jewelry type and healing time. Lip piercings and other oral piercings can take a longer time to heal. They have a higher risk of infection because of the germs located in the mouth and introduced through food, kissing and sexual activity. Any piercing results in a permanent change to the body, even if it is just a tiny scar.
