Apparently, yesterday, it was hotter in the South of England than it was in Miami. If you're looking for a way to stay safe in the sun (and let's face it, we all should be), check out an article entitled 'Don't fry too close to the sun' by Michelle Andrews from USNews.com. You can read the article here: http://www.usnews.com/usnews/health/articles/060703/3sun.htm.
Oh, and I can wholeheartedly recommend the Neutrogena sunscreen that she mentions. If you hate the usual heavy, sticky feel of sunscreen on your skin, try their UltraSheer dry-touch sunblock - within a couple of minutes of application, it feels almost powdery to the touch and it goes up to SPF 55 - I find it absolutely perfect for my face.
