Why do girls wear fake tan? Opinions please?

Well I prefer to be tan because it makes my skin more glowy and not so dull and pale because it just washes my complexion onut when im too pale. Also I get really cold easily and when I do my legs turn purple and my arms turn blue and tanning makes it less noticable. I am prone to skin cancer so I dont like to real tan. I just hate the smell of most self tanners, they make me wanna barf!
