Purple marks on lips: You have to see your doctor or a dermatologist to have a proper diagnosis. There are a number of different possibilities. The most likely is a vascular one such as a venous lake. However many lesions on the lips can reflect a systemic condition like osler-weber-rendu.

Venous lake: Venous lakes are benign blood vessel growths that can be blue or purple in color on the lips. See a dermatologist to evaluate the lesion. They can also be removed by an oral surgeon if they are bothersome.
