At Northern Lights Tan Spa, technicians prevent autumnal pallidness with a bevy of sunless and sun-simulating options. Bask in the warming glow of the UV beds and booths or dance a jig in front of a spray-on My Myst Mystic Tan booth, thwarting the efforts of pale, petty clouds jealous of human melanin. My Myst allows customizable copperfication, and the oscillating spray ensures a dark, even coating. UV tanning comes in an all-brown kaleidoscope of options, from the longer-lasting tans provided by the contoured platinum-level beds ($25 plus tax) to the economical three-session packages of the silver-level beds ($22.50 plus tax).
