A 24-karat lip balm sounds decadent, at best, and a huge waste of money, at worst. After all, why put gold on your lips—where it lasts so fleetingly—when you can wear it around your neck, layer it on your wrist, or clasp it to your ear? That said, the delicate, 24-karat gold leaf in Tatcha’s Camellia Nourishing Lip Balm ($36) adds just the right amount of luxury to a product that more than lives up to the hype. (Full disclosure: I also just enjoy saying I use a 24-karat gold lip balm).
