Fairness help required!?

First, I do not know what makes your skin dark. So, I ume it is due to frequent sun exposure. Then, I would suggest you to stay at home for a certain period and it will become fairer by itself naturally. Or you may have to apply whitening skincare (some are really natural / organic) for better results. If you do gain back the fairness you want, please apply sun block from top to toe in order not to get darker again.
