Eggs are a rich source of protein. For stretch marks, you want to use only the egg whites, which contain amino acids and proteins.
=> Whip the whites of two eggs gently with a fork. Clean the affected skin area with water and then apply a thick layer of egg whites with a makeup brush.
=> Allow the egg whites to dry completely and then rinse the area with cold water.
=> Finally apply some olive oil on the skin to keep it moisturized.
=> Repeat the process daily for at least two weeks and watch for positive results.
