Norvell sunless tan: booth $34, airbrush $50, unlimited $59.99/mo. Walk-ins welcome. How long does a Norvell spray tan last? A Norvell sunless spray tan typically lasts 5–7 days. The exact duration depends on skin type, post-tan skincare, sun exposure, and how often you exfoliate. How dark will my spray tan be? The Norvell INTELLISPRAY formula develops 3–5 shades darker than your natural skin tone, with custom levels available for the airbrush service. Do I need an appointment, or can I walk in? Walk-ins are welcome. To guarantee a time, especially before a special event, call ahead — Farragut at (865) 406-9470 or West Town at (865) 806-5216. Is the spray tan booth safe? Yes. The Norvell spray tan booth uses no UV exposure. The DHA-based formula is FDA-approved for external application and the booth's open design with down-draft technology eliminates inhalation concerns. What's the difference between the booth and the airbrush? The automated booth ($34/session) uses robotic spray arms with infrared body scanning for a fast, even tan. The full-body airbrush ($50) is hand-applied by a Norvell-certified technician for a fully customized result — choice of shade, contouring, and special-occasion touches. How should I prepare for a spray tan? Exfoliate and shave 24 hours before your appointment. Arrive with clean skin — no lotion, perfume, makeup, or deodorant. Wear loose, dark clothing for after the session.
