The product states that it stops dark circles and wrinkles, reduces puffiness and reverses the signs of aging. What I do know it that I haven't seen any decrease in my winkles after using the product for 3 weeks, I do love that it makes my skin feel invigorated and youthful. As far as the dark circles under the eyes, I do not have any but I do have some puffiness, which I could tell that it has gone down slightly. I do like that my skin looks radiant, feels smooth and well nourished.
