Kerrilynn Pamer and Cindy Diprima Morisse of CAP Beauty

Fans of Castor & Pollux—the cozy-cool New York boutique known for its fashion prescience (stocking brands like 3.1 Phillip Lim and Acne before they were big) and celeb following (Helena Christensen, Sarah Jessica Parker, Maggie Gyllenhaal)—are in for a surprise. After selling clothes for almost a decade, owner Kerrilynn Pamer has teamed up with her friend Cindy Diprima Morisse, a former stylist, to convert the store into a green beauty emporium. CAP Beauty, as the shop-spa hybrid is called, offers strictly synthetics-free products from chic eco-conscious mainstays like RMS, Intelligent Nutrients, Tata Harper, and Kjaer Weiss, as well as from emerging brands including May Lindstrom, Dr. Jackson’s, and Vintner’s Daughter. Facials and body treatments using luxe organic brands like Alexandra Soveral are on offer in three back-of-the-lounge treatment rooms.

In thinking about customer service, Pamer and Diprima Morisse were inspired by the wildly successful taxi app Uber. Regulars can keep a credit card on file, and there’s a tip-included policy—meaning no swiping, signing, or awkward small envelopes to interrupt the pampering. And then there’s the duo’s fresh take on the tired old gift card. “Our White Card is a solid slab of white marble that is hand-delivered to your home,” Diprima Morisse says. “It’s linked to the giver’s credit card, so you can buy anything you want.” In other words, literally carte blanche.
