After a five-minute nap on the plane, my face felt like it hadn't seen cream in a hundred years. But it had seen air conditioning, a trillion polluting cars, and non-stop exposure to screens. Now you might think I'm joking about my screens, but it's proven: it's bad for your skin. Besides the harmful influences from inside and outside, the blue light emitted by screens also accelerates skin aging, and I actually want to do everything to slow down that skin aging. At my 30-something (two-and-thirty, yes), the latest invention from Sisley fits me perfectly. The SSisleYouth Anti-Pollution Energizing Super Hydrating Youth Protector sounds just like it is. The cream hydrates, but at the same time lays a blue light shield over your skin, protecting you from pollution and thus also from light pollution. Add to that I've never had such a soft baby skin, and you're sold. The advice is to start applying from your twenty-fifth.
