Airbrush units sibilantly hiss and UV lights hum gently. Patrons, including several former pageant winners, wander among a range of beds, which dispatch bronzing beams to standing or horizontal guests. The electrically hued units have names like ETS Velocity and Sportarredo Extasy, all of them resembling something from a science-fiction film or a supercomputer’s yearbook. Xotic provides protective eyewear, and a range of beds in different levels allows patrons to customize their coloration. Specialists consult in private rooms, helping select the correct shade of spray-tan solution, which dries instantly and is almost completely odorless.
