Make a thick mixture of the three ingredients. Cut a lemon into half and squeeze it on the baking soda. The mixture will sparkle, and then add turmeric. Apply the solution to your skin. If the mixture becomes dry keep squeezing lemon. The color will change from yellow to orange and then it will turn into red until it is maroon or dark brown. You should not worry about the changing color. Just leave it on your skin overnight. You will see a tremendous improvement after the first application. You must continue applying the mixture until your marks disappear.

Turmeric heals all skin infections and muscular ailments. After the first few applications leave out turmeric only mix baking soda with lemon juice and use. This should get rid of the most stubborn stains if you use it regularly.
