Fundamentally, as we've heard before, really what we're trying to do is just to ensure that sunscreen does what it says on the tin. With some products it's pretty clear that that's not going to happen. You know, regardless of what advertising or what products say on the tin, I know that applying it to me is not going to turn me into Rachel Hunter for the simple reason that I'm not blonde—I mean, obviously no other reason. We can laugh but it is a serious issue. We've heard Mr Muller speaking about the impact of the sun on fairer skin. Certainly, I can speak to that myself.
