Spray tans are a great addition to your routine, especially with spring and summer right around the corner. Why damage your skin tanning in the sun when you can come in for a spray tan? Spray tans can be applied as often as you like, with the results intensifying with more frequent use. Your tan will last until your skin naturally exfoliates, usually about a week. My studio has a tanning room that is private and application can be done in about 20 minutes.
