Lip pimples are essentially like any other pimples. However, they tend to be more painful due to the large amount of movement that our lips and mouths perform. Most lip pimples are caused by the same pore-clogging bacteria as regular pimples, but they may look and feel different because they are located in an area of constant use. It may be tempting to pop a lip pimple, but be patient and use a spot treatment instead. With proper skin care and some TLC, they can be treated and prevented in the same way as any other zit.
