What might a hard white bump on my lip indicate?

Milia are small, firm, white bumps that appear when keratin (a protein found in skin) gets trapped beneath the surface. They often show up on the face, including the lips, and are not usually a sign of a serious problem. These bumps are very common and typically harmless. In many cases, milia clear up on their own without treatment. However, sometimes they can stick around, and if they bother you cosmetically or grow in size, a physician or dermatologist can safely remove them using simple techniques. There are other conditions that might look like a hard white bump, so it is important to have any unusual growths evaluated by a healthcare provider. They will perform a more comprehensive evaluation to decide if any tests or treatments are needed.
