Nice serum, but I didn't see any results!

I received this sample through Sampler. I tried the sample of SkinCeuticals H.A. Intensifier which is a multi-functional serum to help amplify skin's hyaluronic acid levels. It is has a light oily texture, but does not leave your skin oily or sticky. I didn't find it to have any scent at all. For those reasons, I liked it. The only reason I didn't give it a higher number of stars was because I did not see any difference in my skin in regards to plumpness, firmness or texture. Perhaps I need to use it for a longer period to see the results. I checked it out on Amazon and the cost was $143 which is way too much for me. I think it's definitely worth a try if you are looking for a serum and price is no object.
