I agree with those who have recommended the Lime scented soaps, anything citrus-y reads young to me. Mama Bear, Straight Razor Designs, Mike's, and most of the major brands make soaps with citrus overtones. Check out the websites and read the reviews. Right now some "younger" scents I use (I'm 29), are Truefitt and Hill west indian limes, Mama Bear's Bonzai, and SRD opus X.
