Has anyone expereinced this or have heard of it. It is very funny... I look like I have a mustache...
Do you know of any type of solution for it.

I would appreciate your input.

I have very fair Irish skin, and whenever I notice random darkening, I rub buttermilk into the skin, as if it was a lotion. Just once or twice a day for a couple weeks, and it goes away. If this doesn't work, I'd recommend seeing a dermotologist.

I have the same problem, it looks like you have a shadow.. I heard about lemon juice or lime mixture with honey, not sure how much to mix.. suppose to be a skin lightener... Anyone have any ideas or the homemade receipe for this?
