Venusia Max lotion or Cetaphil lotion or Aquasoft lotion or Episoft lotion can be used if it is just routine dryness. however an examination would be needed to make sure there is no other coexisting condition along with other underlying cause for the increased dryness. 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. Also you can use Chaptex lip balm twice a day(or even more frequently like 5-6 times if needed... also wet your lips with water prior to applying the balm..) for a few months. Get an online consult privately with pictures or meet a dermatologist directly for a proper evaluation of the condition. Hope this was helpful. Hope this was helpful.
