ABOUT US

Theory Aesthetic MTK is Montauk's premier precision brow atelier, lash haus, and skin sanctuary — a summer residency bringing an elevated, appointment-only beauty experience to the East End. Situated at the tip of the South Fork, minutes from Amagansett and East Hampton, Theory Aesthetic MTK is located inside Jadespace, a wellness brand house in Montauk. One intimate studio space where every service is designed with intention, every technique is executed with precision, and every client leaves looking and feeling their absolute best. At its heart, Theory Aesthetic MTK is a Brow Atelier — led by Juliana Marcucci LE, a highly specialized luxury brow artist, facialist and licensed esthetician defined by precision, personalization, and craft. Using a multi-technique approach including threading, hard wax, soft wax, tweezing, precision mapping, and freehanding, every brow is designed from scratch to suit your unique face and features. This same attention to detail and precision carries through to what are conceptually the Lash Haus and Skin Sanctuary. Though sharing the same exclusive studio space, each is equally bespoke. Lash Lifts, Tints and Korean Lash Lifts are designed based on eye shape, lash type and eye color. Personalized facial treatments focus on barrier restorative care and skin positivity. Theory aesthetic MTK is in residency at Jadespace in Montauk throughout the summer 2026 season. 786 Montauk Highway, Montauk, NY 11954
