new skin 

refers to human skin that has never before received tattoo ink or any other form of permanent cosmetics. Sometimes also called virgin skin.

The process of healing a tattoo is expected to be somewhat different for first-timers with new skin, who might not heal as quickly as a tattoo addict whose body is already familiar with the ink.

law of new skin 

is a theory that no matter how hot or sexy your current piece of ass is, the girl you haven't slept with yet is more desirable

you are currently in a relationship with a 9.2.
but you really wanna bang the 6.7 with the crooked teeth at the end of the bar.
The law of new skin says that you will sleep with the 6.7
