Last summer I was out in the sun for the day and afterward I noticed the area above my upper lip darkened. I always used to use lotion with sun block on my face but had forgotten it that day. I've heard that this can happen from taking birth control and I've been on the pill for several years. It didn't fade at all over the winter. I started using some bleaching cream on it but it only seems to be helping a little. I'm going to be going off my pills now. Will this go away once I've been off the pill for a while? How can I get rid of it? It's really embarrassing b/c it makes it look like I have a mustache.
