Fifteen-year skincare veteran Manisha Sareen traces her aesthetic passions back to her native India, where her mother and grandmother taught her how to care for her skin. Today, those age-old lessons fuel the attentive care she and her staff shows every client at Eyebrow Threading Spa. Inside a cozy studio with lilac walls, the specialists perform their signature threading service, in which they roll twists of fine cotton string along the brows to shape them more quickly and accurately than with techniques that use wax or velcro. Staffers also wax away body hair and perform a retinue of facials that target acne, dryness, and discoloration. For whole-body enhancement, therapeutic massages soothe tense muscles, and the semipermanent pigment of henna leaves intricate adornments on hands, shoulders, and other features.
