Infection after frozen mole: green pus. (Photo)

Obvious moles can really make a patient self conscientious and are so easy to remove. The resulting minimal scar is so much better looking than an ugly mole.

I would not recommend attempting to permanently make a mole darker.  If you would like the mole removed and it is raised, this can normally be removed by shaving it off.   

The mole on your upper lip appears to be raised.  If that is the case, it could be shaved off to remove it.
