Suggest Ways To Attain Fairer Looking Skin

My complexion is brown. It used to improve when I drink canned mineral water. But i m getting darker & darker now a days as I stopped using canned water for drinking & cooking purpose. I would like to regain my complexion and even get fairer. Any suggestions (like applying cream etc). I was told by a friend that adding a pinch of haldi(turmeric) in glass of milk before going to bed would help. Please advice. Thanks!!
