How to darken a birthmark

Question: Hi! I know this is an odd question considering that most people would like to have the opposite problem that I have but I have a birthmark just below my right eye that i've had all my life and it seems to have faded over the last year or so. I've grown to like my bithmark, I feel it makes me lool unique and I wanted to know if there is any way to darken it. Thank you for your time!

Sun exposure usually darkens any type of mole or hyperpigmentation, however I do not recommend tanning or laying out in the sun. Otherwise you can darken the area with a makeup pencil Best skin care wishes.
