'My point is if someone tried and change how they look by using a spell it goes against science theres a video on youtube' is that two sentences? like '... goes against science. There's a video...'?
it's true one cannot use magic to go against science like changing your appearance. what video on youtube? a link would be helpful. [side note, i mean no offense, you might want to work on you spelling/grammar, it can get a bit confusing at times. for me anyway.]
you do make a point, certain beauty spells effect your confidence more than your physical appearance. i know what it's like to worry about how others perceive you, but you really just need confidence. it's tough, i know, but there will come a point where you just say 'screw you' and ignore other people. yes, little things like potions to clean your skin isn't bad, but trying to cast spells to look a certain way A. won't work and B. will make things worse.
