It works!
Size: 1 Count (Pack of 6)
Got this for my husband and it really works. He left it on while he was drinking his morning coffee. He's 1/2 Asian and has normal puffy eyes from dusk to dawn. It's just been been one day but the results were truly amazing. Puffiness 75% go e in one eye and 50% in the other. Im impressed.

A must read book for EVERY couple
Format: Paperback
Life’s hard these days, and it takes a toll both individually and especially on relationships. Throw kids into the mix and it gets even harder on steroids. My wife and I are pretty empathetic and forgiving people, but even we found ourselves struggling with the demands of everyday life. We finally decided to try couples therapy, and our therapist recommended this book. I’m not a huge fan of books like this because I usually find them to be high minded, overly theoretical, and lacking in effective tools and practical solutions. This book is none of these. It is very approachable and written in an easily-digestible and conversational style, but most importantly the information is extremely insightful and helpful in understanding ourselves and how this affects and plays out in our relationships. And it provides very doable and effective tools and techniques that can be enacted easily and that yield fast and significant results. The first few chapters alone have improved our relationship 10 fold as we now better understand where each other is coming from AND WHY, along with how this impacts our communication, behaviors, and feelings. And the tools are there to help us incorporate positive strategies into our daily lives to help keep us on course going forward instead of just lapsing back into our old ways over time, which is the downfall of many other books like this.
I wish we had read this book before we got married as it would’ve helped to avoid lots of needless and hurtful arguments and bad feelings that lead to unproductive and harmful walls that just get harder and harder to break down over time. Frankly, I think this book should be required reading for every couple as it would help prevent so much unnecessary pain and suffering, and probably divorce as well. I’m a guy and hate talking about feelings, emotions, etc., but even I have enjoyed reading this book and certainly the happiness and joy that has returned to our lives. Life’s too short to deal with the stress and negativity of a struggling and strained relationship, so get this book and put your relationship on a happy, healthy course. It’s really life changing with relatively little effort.
