Trust me, I don't feel bad about myself in the least, but I think your attitude is unfortunate because it's just irrational. I never once said a spray mist is UV protection. I wear a moisturizer with sunscreen every day and sunscreen on top of that when I'm going to be outside for a while. I recommend everyone do that even if they don't tan-I do have a family member that is young, didn't tan, was careful about sunscreen at all times because they burned easily, that still got skin cancer. But obviously tanning beds increase that chance. A lot. So, once again, I'm against that. But I can't understand why you judge women that use make up, spray mist or hair products. Is nail polish the devil, too?
There are much bigger problems like pressure to be unnaturally thin, pressure to get cosmetic surgery, pressure to go sit in a cancer box, etc. Railing against people who use safe and healthy ways to feel well groomed and cute is ridiculous. I wish young women would be encouraged to play with make up, a Neutrogena spray tan, correctly fitting clothing, and some styling products to help them understand there's absolutely no need for radical and invasive cosmetic procedures, tanning beds, unhealthy eating habits, and damaging chemical straightening or perming. There's nothing wrong with using none of those things either (except the healthy eating habits, obviously), but there's nothing wrong with USING safe and fun alternatives, either, and what I can't understand at all is your judgment of people who wear make up, nail polish, style their hair, or use a Neutrogena spray mist. Wearing make up doesn't indicate that a woman doesn't like herself, and throwing it into the same category as tanning doesn't help anyone feel better about themselves. So no, I do not see a connection between spray tan and horrible self esteem issues.
There is nothing at all un healthy about a healthy, sprayed on glow, face powder, or nail polish.
