Tanning ruins your skin!!!! You won't realize how much until it starts to show and then you will freak out. The best way to counteract earlier tanning binges (I spent many years in Hawaii and California) is radical use of retin-A and sunscreen. And remember, as I did not, that your neck is connected to your face, so whatever you do for your face, do for the neck as well.
Take the advice of a woman who learned in the nick of time!
