I've toyed with the idea of spray tans, etc. Never got round to it but always wondered how something could change your skin color but not really go past the skin. I mean, even some shampoos and moisturizers come with warnings! Even when I was pregnant I remember looking at spray tan products and it was not warned against even for pregnant women. Have to say, when I was pregnant I used NOTHING except baby, shampoo, ivory soap and eucerin (sp?). No make up no special moisturizers. Oh, yes, I was a sight to behold.
Really scary when products that have been around forever turn out to be "not so safe." Makes me paranoid about everything!
