I vote for recognizing clear risks, and taking appropriate steps to mitigate them up front. If you're deliberately trying to put biologically active stuff into millions of people, it is just a question of time before the law of unintended consequences hits you. Your desire to sell more effective skin whitening creams does not, in my books, mean that you should ignore the possibility that your beautifier can make people sick. And if you're in doubt, I want you to err on the side of safety.

Of course if you're selling something that we have good evidence is both acceptably safe and makes people look better, then the more power to you. But that's not, by her admission, the position that she is probably in.
