Biophysicist Diana Seo opens her second NYC spa (the first is in Soho), specializing in a multipronged approach to skin care that combines Eastern practices with advanced medical techniques. The full-service spa offers massages ($98–$368), waxing ($18–$88) and nail services ($35–$100), but we recommend the customized facials ($98–$450). After a close examination of your epidermis, an aesthetician will create a unique blend of herbal tonics and medical-grade solutions targeted specifically to your skin’s needs. Try an organic stem-cell facial (60mins, $450), which aims to improve skin at the cellular level, or the Ayurvedic Yoga Beauty facial (45mins, $256), which uses essential oils and a signature chocolate-tamarind mask. On your way out, be sure to check out the array of natural and organic products, including Me & the Girls lemon-scented body scrubs ($32), Lauren Fritsch jasmine-and-patchouli fragrance sticks ($48) and B Spa hydrating skin mists ($28).
