An Amazon reviewer says: “I bought this serum because makeup settles into the lines under my eyes. I read [that] eye cream can exacerbate that and to use a serum instead. I didn’t want to spend a fortune, so I chose this. I am so glad I did! I have very dry skin, and I have tried every moisturizer and eye cream under the sun, from luxury to drugstore. I’ve found a facial moisturizer that works well, but never felt like an eye cream did anything my facial moisturizer didn’t already accomplish. Until this one! This sinks in deep, my lines blur from the hydration, [it’s] not greasy at all, and it stays until I wash my face and re-apply. Although it didn’t prevent my make-up from settling into the lines under my eyes, it was definitely an improvement over an eye cream, just regular moisturizer, or nothing at all. Plus, my under-eye look less crepey when I use it. I’m not sure if there is a ‘permanent’ improvement, but I can see and feel the daily difference between using it or not.”
