Always wear a moisturizing sunscreen when the skin is exposed to the sun. Avoid using baby oil or lotions that contain lanolin because they encourage as well as intensify burns. Apply aloe vera gel to the skin before and after sun exposure. Use a lotion that contains PABA to deepen a tan without excessive sun exposure. Apply chilled apple cider vinegar, aloe vera gel, or plantain frequently to a burn to nourish it. Try one of the following for a sunburnt face: Apply a mixture of milk and whole wheat flour to the face. Leave until dry and remove with warm water. Rub olive oil onto a burnt face. Apply a paste of barley flour, honey, and raw egg white. Leave on for thirty minutes and then rinse with warm water.
