You may have noticed that your lips turn purple or blue in the cold, or you may have seen a baby, an elderly person or someone else with bluish or purplish lips. In many cases, this type is caused by cyanosis, which is a discoloration of a part of the body resulting from a lack of oxygen in the blood.
If that black spot on your lower lip is scaring you, a dermatologist explains four possible causes including cancer. Keep in mind that what appears to be black may actually be a deep dark purple, or, if the speck is small enough, you may notice upon very close inspection that itâs actually medium brown.
