A must to have on hand (or any part of your body, really) on rigorous install days and then some: Zincuta, a time-tested natural remedy for minor skin abrasions, insect bites, sun burn, chafes, even eczema. Containing zinc oxide, beeswax, wound-healing styrax benzoin and essential oils, this herbal-scented emollient, inspired by a century-old ointment, has been reformulated in Brooklyn by herbalist Donna Penney. A 2-oz. tin is $12.50.
