Hello, I can understand your concern for fairness and that too for permanent basis. To tell you regarding the skin color-our skin color is determined by the activity of particular cell known as Melanocytes. These melanocytes are secreting color according to the genetic basis. It means if a person has more activity than we can not change it by any medications. SO for you also I suggest you to not get carried away by anything to get fairer. There is nothing in this world which can change our genetic capacity to secret color. Eat your best of nutritional diet and protect yourself form sunlight. All the best.
