How should we see perceptions of beauty especially since Hollywood and celebrities have such a big influence?

They do totally have a huge influence, and they are completly unrealistic ideas we have in our minds.
a) there are always some very good looking people, and the most good looking of all the good looking are in our magasines. so its an unfair comparison for people to make.
b) airbrushing. did you know lots of ‘paparatzi’ shots you see are set up, with airbrushing. so the celeb gets publicity and so the magazine has the shot first.
c) not many of us get our hair and make up done at least every other day. not many of us live in somwhere where it is always sunny so we are perfectly tanned. not many of us have a personal chef and trainer stopping us eating anything and gaining weight, if we did who needs self control. not many of us can spend so much on clothes making us look that great.

so if you take the most goodlooking people with all that extra help to look amazing, and then airbrush them. why should we compare ourselves to them? its crazy..
