This roller works great to help with puffy under eyes. It's a cold metal ball so it helps almost instantly once you start rolling it on. I had a hard time getting the roller ball to move immediately so I suggest moving it around with your finger before rolling onto your eyes, so that it's working properly. Also for me, it dropped off my counter and because it's glass it broke once it hit my floor :( Before I broke it, I was using it about every other day, and I liked the calming effect it had on my skin! #rankboosterreview #sponsored #eyeserum
