if you need a permanent solution it would take some time, some of really easy natural methods to get rid of these dark spots are 1)Apply lemon juice directly to the affected area. Leave it on for about 30 minutes before rinsing it off. Lemon juice bleaches the dark spots, and you'll see noticeable effects in about 2 months. 2)Combine honey with lemon juice to make a paste. Apply the mixture to your brown spots and rinse it off after 30 minutes. Lemon juice dries your skin, but the honey provides moisture to protect your skin from damage. 3)Mash strawberries and peeled apricots together to make a paste. Then, apply the paste to your face to get rid of brown spots. Leave it for 15 minutes and then rinse it off.
