96 Ann, this product has light reflectors in it, it does a great job at making the eyes look "fresh" it also has mushroom and soy- idk how well it decreases wrinkles and how much lifting its going to do, but its helping my under eyes look "wholesome", im satisfied with it myself.
The best way to prevent dark circles under the eyes is to eat, drink and sleep well, reduce stress and combat fatigue. You can try turmeric powder and pineapple juice. The presence of curcumin (antioxidant) in turmeric powder can treat free-radical damage caused to the cells around the eyes, thereby treating dark circles. You can apply a paste of turmeric powder mixed with pineapple juice and apply it on the eyes for about 10 minutes everyday.
