Once you have successfully removed the dark spots from the body, it is essential that you prevent their reappearance. Do not prick the pimples, boils, or any infections on the skin, as they tend to cause dark spots later on. Try to avoid going out in the sun. If it is not possible, then you have to generously use a sunscreen lotion on all the exposed parts of your body whenever you step out in the sun. This should be followed even in winters.
