When I was young I played in the sun so much with out sunscreeen, now I use sunscreen but I just want to get back to my light skin, so I am planning to use a skin lighter,

THE PROBLEM: I am only 15 and I don't trust stuff on the internet, neither my mom won't buy anything off the internet (credit card fraud), I was wondering if anyone knows where any good skin lightner in Wal-mart, Shoppers Drug Mart or Zellers?

I live in Canada, so some stores in the US, won't be here

Thanks for you answer!
