I've bought the Serum several times for my wife, and she loves it! The only suggestion she has is that she wishes the bottle could be bigger since she uses it on a very regular basis.
I love Super-Oli Serum because it is so light. It absorbs so quickly and doesn't feel oily or tacky. I can see a difference in the skin underneath my eyes - it's no longer dry or tight feeling. Also use this serum on my stomach after a shower. I am diabetic, so multiple injections daily can cause some problems with injection site wounds and thickening. Super-Oli Serum helps!
