holy guac-a-MOLE-y , not a smart thing to do.
that shit made me a slightly orange dalamation, I had so many freckles and dark spots pop up out of nowhere
I have wondered about it's use for laser hair removal, since it darkens the hair follicle along with the skin - so if you have light hair you might be able to get it zapped after a few weeks on the M2, then ceasing use so your tan fades.
