Do Magazines affect teens self esteem?

I think most teen magazines set out to increase teenagers' self-esteem, but instead just lower it. Magazines include pictures of celebrities and "how they are just like you," health tips on "how to get a better body in five minutes," and fashion makeovers that no average person would really try. I think that by the very fact that magazines try to make us feel better about ourselves, that we can get the same "great buys" as celebrities and look "just like them," they are in actuality lowering our self-esteem. Because the truth is, we are not "just like celebrities" - they have more money, more fame and more resources. We make do with what we have, and that's just fine, but magazines pushing it in our faces, always encouraging us to not feel bad ourselves, that does the exact opposite.
