Ok well about 3-4 weeks ago i went on vacation to an amusement park, and when i came back i realized a small dark spot on my lower lip. So i decided to visit the dermatoligst. Then he reccomended this ointment for me. I used it for a couple of weeks but nothing happened. I remember him saying how he might have to do a biopsy, but i don't want them to because idk how long it'll take to heal and i don't want to go to school looking like that. Today i thought about using cocoa butter, can somebody tell me what's wrong and what can i do to make it better?
