Whether you're Irish or not, taking proper care of your eyes keeps them smilin'. Eyes are often the first thing people notice, so you want to ensure that you keep yours bright, beautiful and happy--and that means proper cleansing, exfoliating and moisturizing. For most people, the skin around the eyes is thinner and more sensitive than other parts of your face. Thus, the telltale signs of aging, fatigue and stress -- fine lines, wrinkles, puffiness, stretching and dark circles -- are more visible around the eyes. There are almost no muscles under the eye skin; a lot of tiny blood vessels are located very close to the skin's surface, which makes this area more susceptible to damage.
