If the story is true, then I question her ethics. As http://www.preventcancer.com/consumers/cosmetics/cosmetics_p... (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…
I really don't know what's worse, cosmetic companies putting whatever they want or this exaggeration of risks Among that list of "dangerous substances" we have: talc, silica (sand). Exaggerated alarmism and "think of the children" mentality. I'm sure there's some people that die after consuming Vitamin C supplements, but that doesn't mean it is 'dangerous'. Do you know what else is carcinogenic? Sunscreen. Of course,…
...if sunscreen penetrates into the skin, it promotes indirect DNA damage, which causes the most lethal form of skin cancer, malignant melanoma. This form of skin cancer is rare, but it causes 75% of all skin cancer-related deaths.
So, while the sunburn you get without wearing sunscreen technically causes more cancer, it is of the mild and nonfatal kind. Now I'm left with one more dilemma added to good vs. bad cholesterol, omega-3 vs. omega-6, natural vs. alkali-processed cocoa, etc.
