Because winter’s effects on the skin have been especially galling this year, and the usual hedges—facials, lasers, and the like—largely off limits, we’re increasingly dependent on at-home remedies. A new favorite: Guerlain’s Abeille Royale Double R anti-aging serum. When it comes to sourcing the most effective ingredients, these people do not mess around. Thanks to a partnership with the Brittany Black Bee Conservatory, sustainable methods are used to produce Royal Jelly, a natural source of proteins, lipids, vitamins, and more that minimizes the appearance of wrinkles and creates a plumper, smoother surface. Apply one or two pumps twice a day, and the effects are akin to a restorative weekend at a spa far, far away. (Starting at $160, nordstrom.com)

Air Mail is the type of operation that has a #tennis channel on Slack. Although a fancy racket can’t compensate for a weak backhand, a smart court ensemble is non-negotiable. And this beauty from Saint Laurent’s Rive Droite concept store, created in collaboration with Wilson, is an ace. Made of carbon, it delivers performance, but its real value is in its distractingly good looks. Rush the net, activate your volleys, and wish your opponent the best of luck, because how is he or she supposed to be focusing on lobs when there is a checkerboard pattern to admire? It comes with a smashing checkerboard case, but the matching balls and black leather ball case are sold separately. (And highly recommended.) ($770, ysl.com)

Viola and Vera Arrivabene—sisters, Venice natives, and ViBi Venezia designers—first hooked us with their velvet Furlane slippers, and they’ve done it again with a cold-weather style that is equally appealing. Made of cozy shearling, which is also used to line the footbed, they look and feel like slippers but are far more elegant than the average pair. And the durable sole ensures that they won’t turn to mush if worn outside—but only on dry days. ($270, net-a-porter.com)

For those who consider G.P.S. to be a thing of beauty, 15A Studio has some new earrings for you. This collective, which helps artists translate their work into pieces of fine jewelry, has enlisted Lucrezia de Fazio to turn your favorite Google Maps itinerary into a golden thread, which can be made into a pendant, hoop earrings, or an ear cuff. The idea is to commemorate connection, and de Fazio’s pieces make a beautiful gift for a far-flung friend, especially in these solitary times. (Starting at $182, 15a-studio.com)
