Hello Sofia
you can definitely use the besan and milk ubtan, and also try massaging the area with ghee about half an hour before bath.
another very easy way to lighten the area to its natural skin colour and reduce pigmentation is to rub half of a lemon on the area. lemon juice acts as a natural depigmentation remedy. you can also try using coconut oil in the same way as it will help to reduce and prevent any pigmentation.
i have tried all the above methods and they have helped, so am sure it will help you too
