Summary
Actinic cheilitis is a potentially malignant lesion on the lower lip, which can progress to more serious illnesses such as cancer if not treated. Usually treatment of this condition is only based on clinical appearance, but there is no established cure treatment. Topical imiquimod is a medicine indicated for the treatment of skin diseases, but it has not yet been proven to treat actinic cheilitis. In this research, the investigator's aim is to evaluate the response to actinic cheilitis treatment with the current standard treatment compared to high and low concentration imiquimod topical formulations.
