Bleaching has temporary results. U need to repeat it every few days. You can apply aloe vera juice/gel from its leaf (fresh), not from ready made gels available in market. Remove skin of an aloe Vera leaf. Take /scoop out gel. Apply this gel to your skin. Wash with plain water after an hour. Or keep it overnight.
Use some sunblock with SPF (at least 50) every time you go out in sun. Apply it 30 mins before going out
Wear full sleeves shirt.
Use umbrella when going in sun.
