Vinegar has a tonic action that promotes blood circulation in the small capillaries that irrigate the skin, and it regulates the pH of the skin. Cleopatra knew that even back then, so she used apple cider vinegar to rinse her face. For the rinse you need 1/4 cup of apple cider vinegar and 1 basin filled with warm water. Pour the apple cider vinegar into the warm water. Thoroughly splash your face with the rinse. And, then let your face dry without using a towel. Before you do this, be sure to start with a perfectly clean face!
