Oily booty pores?
Oh well at least she isn't prone to wrinkles on the ass from having oily skin. ![Undecided :-\](http://www.getbig.com/boards/Smileys/classic/undecided.gif)
Yep, it could be that...but more than likely it's friction zits...and what happens is if the zits are pops, they leave those scars---blemishes. One has to use something to clear them up, like proactive or a lightening cream.
