Cosmetics work fine on TPE sex doll, even lipsticks. Buy a $2 odorless mineral oil at the hardware store. It can remove tpe and even clothing stains, but don't count on this. I pierced my TPE doll ear. Then I finally tore a bit behind her ear. Not sure if the two are relevant, but it may be. My guess is that it is good to pierce a TPE sex doll, but you must be very careful not to grab it on anything. It may be a good idea to wear out during game time.
