Query: Worth it

I thoroughly enjoy this product and think it works well for me. I'm a female in her 20's and I was starting to notice dark circles under my eyes, so I bought this product. Within 2 weeks I noticed a difference. My dark circles have lightened and my skin under my eyes seems tighter and more bouncy. People around me seem to have noticed as well because when I dont wear makeup I no longer get the, "you look sick/tired" comments! I gave it 4 stars instead of 5 because I use other products in addition to this one which could be aiding its effectiveness. And also the fact that I'm in my 20's so my skin is *relatively* fine-line and wrinkle free to begin with.
