All crave for a beautiful, fair skin all over. I have a few doubts in this regard.

1. I have heard that consuming honey and lemon in the morning daily will make you fairer. I want to know, will this combination really increases the color or simply make the skin look healthier/ how long will it take for obtaining a really fair skin?
2. I know that apart from genes, melanin is responsible for the color of one’s skin. Can lemon and honey work against the effects of melanin?
3. How did dark skinned Michael Jackson get that very fair skin in his later years? What is the process called? Is it safe?
