Gentle music breezes past the salmon walls at Sophisticated Facial & Nail Spa, where black, leather massage chairs rest on natural-wood floors. Nail technicians with a keen eye for artistry paint fingernails with such specialty designs as zebra print, flowers, butterflies, and near-perfect replicas of toenails. Dermalogica products nourish visages during a half-dozen different 90-minute facials, which range from an oil-and-acne treatment that uses high-frequency currents to kill bacteria to an anti-aging facial powered by hydroxyl-acid exfoliation. Private treatment rooms also host waxing procedures that leave skin smooth and hairless for longer than razors, tweezers, or stern lectures do.
