I've been using this eye treatment for about 2 and a half months now. I'm almost 40 and noticed I have really dsrk, puffy circles under my eyes. I know it's die to lack of sleep, but nonetheless they're still visible. I have started to notice light wrinkles too. I decided to try this because of the great reviews. I'm so glad I decided to try it. First of all, it's very lightweight. It goes on smoothly and doesn't make my skin oily. It is very light scented too. Second of all, it's very gentle on the skin. I have semi sensitive skin and it didn't sting or burn. Last, my bags under my eyes really look better. The puffiness isn't as noticeable. I even purchased the 5 in 1 night cream because of it and see such a difference in my skin. Totally worth it!
