Hi Kāvya, Thanks for your query . You can do the following : 1)Sunscreens : A broad-spectum sunblock with SPF 30 or above and having both UV-A and UV-B protection, should be used before stepping out of the house. You must apply this 20 -30 mins before going out. Reapply after 4-6 hours. Using this even if you are not exposed to sun directly is recommended.2) To reduce existing pigmentation, you may consider going for Glycol peels with a qualified dermatologist once every 15-30 days for a few sittings and then maintain the results using the above protective measure.3) vitamin C orally (1000 mg) per day for 3 months will help to lighten faster.4) For the darker areas, you may consider using creams having Glycolic acid or Comic acid and It. C 5) Do not use OTC moisturizers before sun-exposure. Several OTC products have photosensitizing agents and actually make the skin darker. It is good to use the sunscreen alone or if the skin is Chat Doctor.  Hope this is helpful. Take care!
