The Dangers of Free Skin Formulas

A lot of companies now marketing their products as free of all this stuff. Art says there's not really always sound science behind why you're taking it out, right? Take parabens, for example. The whole thing behind parabens is there was a study that was done where they found parabens in tumors from breast tissue. But the problem with that study is there were also parabens found in the blanks with no tissue, with no tumors. So how do we know these people even use skincare and then get it from somewhere else? How do you know about their medical history? Anything, anything.
