Prolonged exposure to the sun dries out and irritates your skin. Splash your face with thermal water to sooth the burning sensation. Then pat your face dry with a tissue. Avoid letting your skin air dry: when water dries on the skin's surface, it also absorbs the water that is found naturally in the epidermis.
