How do i get rid of the red ring around my lips?

What is the cause: Before you can get rid of the ring, you need to know what is causing it. Is it an allergic skin reaction to foods you have eaten? Is it a kind of dermatitis caused by licking your lip? Are there any other symptoms along with the redness? Is the redness there all the time or does it come and go? Are you on any medications? Consult your physician for examination and testing.
