Everyone has different skin concerns so I don't want to discourage anyone from purchasing this - I got the mini to try out so maybe do that, before you spend your hard earned moola on the big sized one. I didn't see any difference in my under eye area, even after using it for a month. It did irritate my eye area and I had to stop using it because it was getting really uncomfortable. I do have really dark circles and extremely sensitive skin so my expectations weren't very high.
