Hi, I can understand your concern for fair skin. Skin color is basically a genetic feature and accordingly we have our own skin color which can not be changed forever. If I were your dermatologist then I would have suggested you to use azelaic acid cream or Kojic acid cream or glycolic acid cream or licorice extract or arbutine creams at night time in guidance of dermatologist. The most important part is to protect yourself form direct sunlight. Take a proper guidance and follow up with a good dermatologist so that all the problem can be dealt best for future time. Rather than taking glutathione pills I suggest you to have best of diet containing fruits and green leafy vegetables to improve skin color. Take care
