The easiest use of whey for skin care is a whey bath. Simply add 1-2 cups of whey to a tub of fresh water. Soak for 10-20 minutes. The acidity of the whey is great for restoring the pH level of the skin, and the whey proteins will help rejuvenate skin cells. Use the same approach for your face with a whey toner.
