I have been using this eye serum for years and always make sure I buy a new bottle before I run out. I have tried so many expensive eye creams, serums, elixers, etc. by all the big name companies. Nothing comes even close to making my tired, puffy eyes with dark circles look bright and youthful. I am not exaggerating when I say with 100% confidence that these products are the reason people find it hard to believe I am the mother of a 20 something year old. I may be in my mid 40s but I am often told I look like I am in my mid 30s. Premier is so expensive at even their own site. Buy them through Amazon. It will be the best thing you can do for yourself. I'm vain enough to want to hear those compliments over and over. With that said, I will continue to use Premier's products over and over!
