I have dark circles around my eyes and, after having sinus issues and surgery, I used to get puffiness some mornings... No longer! My dark circles are definitely lighter - after using every eye cream on the market, this is the one thing that really made a significant difference. This was the only reliable way of dealing with the puffiness, which now never even appears in the first place after consistently using the Iris. It's got rid of it entirely!
It's amazing how well this product improves drainage around the eyes - much better than manual massage ever could and in much less time.
I recommend smearing on a lot of eye cream or a thick moisturiser (I like Embryolisse or Clinique All About Eyes Rich) - enough so there's a visible layer over the skin. That will help the device to glide over the skin without any tugging. Then move it all around the eye with very light pressure, including down beside the nose a little. I then let whatever eye cream is left on for another 5 minute to really sink in. I use it religiously twice a day and have seen great results.
I recommend this product to everyone who needs help with puffiness and dark circles. It's hard to believe how well it works until you've tried it.
