This product is pretty heavy duty and works quite well! I have been using it every other night for about 1 month and it claims that after 2 weeks, under eye puffiness and crow's feet appear reduced. I would have to agree with that claim. Upon first use, my under eyes felt very hydrated and I am noticing a small reduction in puffiness and my wrinkles look slightly smoother. It does claim to reduce dark circles and while my skin tone appears more even, I don't think it has helped dark circles yet. It is fragrance free and a very small amount goes a long way!
