On the day of Alexander Wang’s spring 2015 runway show, New York was unbearably hot and muggy. But this was good news backstage, where the makeup artist Diane Kendal was going for a dewy look in the spirit of the athletics-inspired clothes. To achieve such a gleaming complexion in the dead of winter, start with a high-tech hydrator like Chanel Hydra Beauty Micro Sérum, which delivers camellia oil extract deep into the skin. The New York dermatologist Amy Wechsler recommends applying the product right after cleansing—“Damp skin acts like a sponge,” she says—and sealing it in with moisturizer. We like Chanel Sublimage La Crème, which leaves skin glowing. No humidity required.
