Dryness on skin is actually dehydration . . . as weather gets colder, moisture drops to the ground, and there is less moisture in the air, causing moisture in the skin to evaporate. For dry skin, try 1 tsp finely ground cornmeal, 1 tsp sour cream, 1/4 orange (juice squeezed), 1/2 tsp grape seed oil or avocado oil, and 1/8 tsp salt mixed together to form a paste. Gently massage into skin for several minutes and rinse with water.
