I look at it this way mineral oil, car oil, are close both being petroleum based now do you really want to put something that can go into your car (which is metal) onto your face. Yes it's cheap stuff, and no doupt the companies put in as a filler, but if you think about it how good can it be for you? I normaly read what is in the products I buy, I never buy things for my skin which are petroleum based. If I need oil on my skin I go for Coconut oil or as a last resort Extra Virgin Olive oil.
