Sandalwood is another effective option.
Make a thick paste of 1 tablespoon of sandalwood powder, 1 tablespoon of glycerin and 3 tablespoons of rose water. (If you don’t have rose water, you can use milk or honey.)
Apply the thick paste to the affected skin area, leaving it on for a few minutes. Wash off the paste with lukewarm water.
Follow this remedy once daily until your black spots vanish completely.
Your vegetable drawer is another source of home remedies for black spots or dark patches. Potatoes can be applied in one of the two ways:
Slice up a potato and place one slice directly on the black spots; leave on for a few minutes and then wash your face with lukewarm water.
You can also make a face mask by combining grated potato with honey.
