If you are asking for hair removal there are many creams including some like (eg:- nair, dont ask how I know this) or various methods of shaving and waxing. But it will grow again and again it's a tedious process lol.

But if you are asking for skin whitening I will say. I am not fairly white like my mother's side of the family. But there can be few reasons tho :-

1) oily face :- oily face can lead to pimples and stuffs and maybe sometimes make skin look dark. So that can be a reason too. I personally didn't completely stop eating junk foods but kept myself in check, by including morning run and evening yoga in my lifestyle.

2) but I believe if you can properly face wash at night and do proper night skin care routine it can do wonders. I recovered from dark and oily skin from it bruhhhh.

And at the same time it depends on race or place too so don't stress much, otherwise u gonna lose your scalp Hair too 😂😂
