Hello Rajeev, let me tell you that there is a bit of a difference in complexions between the body parts, the exposed areas are darker as compared to the covered areas, to minimise it, u need photoprotection, which is to be done even if you work indoors as UV rays enter through the window glasses. Use a broad spectrum sunscreen with a minimum SPF of 15 like shadow sunscreen lotion, use fash facewash for washing ur face twice daily, and if u have circumscribed dark patches or spots, u need to visit a dermatologist for evaluation. There are various cosmetic options for glow like chemical peels etc. Thanks Take care
