It's endless summer at Wolff Tan USA, which offers tanning beds, stand-up beds and sunless spray tanning. If your skin color is good but your teeth could use some work, Wolff Tan USA has a teeth-whitening service (and offers specials on its website). During dreary cold months, stop by for light therapy, which not only improves a mood but is used to decrease fine lines and wrinkles on the face.
