If the diversity of the spa services in her repertoire is any measure, licensed aesthetician Julia Ostro’s beauty skills are singularly well-rounded. She draws on the power of natural botanicals and carefully calibrated cosmeceuticals to cleanse and perfect skin. Ostro customizes facials and peels using products from brands such as Vivant Pharmaceuticals. Services can be enhanced with add-ons, including galvanic treatments that help facials go the extra mile toward creating firm, scientifically literate skin. Natural nutrients from green clay and seaweed enrich body wraps and nourish skin during relaxing 60- to 90-minute treatments. To care for bodies and calm minds, she also offers private Hatha yoga sessions.
