arthritis in combination dryness of skin... if present with redness and photosensitivity can also be indicative of a systemic autoimmune disease... need to examine the skin. The cause for the pigmentation needs to be determined. Smoking is one of the common causes for darkened lips. Stop smoking if you smoke. The darkness can also be present because of nutritional causes OR because of inflammatory conditions(like seborrheic or perioral dermatitis) OR with a superadded component of perleche. A proper detail examination would be required to try to assess and identify the culprit cause. You could visit me at my clinic if you wish. . Hope this was helpful.
