Fine serum for winter months!

I've been using this serum together with the facial cream for 4 weeks now. At first I was afraid an oil would make my skin oily by day, thankfully this didn't happen! After cleansing my face and a toner, I apply 3 drops of this serum to my face. It absorbs quickly, then I apply the facial cream. It gives me a nice shine on my face, without leaving a greasy layer. For now in winter I like this serum very much. I'm curious if it won't give me a greasy home in the summer.
