If the story is true, then I question her ethics.<p>As <a href="http://www.preventcancer.com/consumers/cosmetics/cosmetics_personal_care.htm" rel="nofollow">http://www.preventcancer.com/consumers/cosmetics/cosmetics_p...</a> (among many other sources) points out, we do not have good regulation of the cosmetics industry. Which is kind of scary, because the cosmetics industry is deliberately seeking biologically active stuff, and smearing it all over people. Stuff that, in her case, does things like change your natural skin color.<p>What else does it do? We don't really know. We do know that a lot of these substances can cause cancer. We know that cosmetics mimic biologically active stuff in our body that could do other things. We know it has not been studied.<p>The last point is important. As <a href="http://www.cancer.org/cancer/cancercauses/othercarcinogens/athome/cosmetics" rel="nofollow">http://www.cancer.org/cancer/cancercauses/othercarcinogens/a...</a> makes clear, the situation right now is, "The jury is out, we don't have data." But I'd be firmly on the side of, "When you're deliberately trying to get the body to interact with biologically active stuff, it is just a question of time until you succeed..disastrously."
