Caviar Based Products and Oils for the Skin?

I have heard that caviar based products (La Prairie) are good for the skin. However if one cannot purchase caviar or the La Prairie line, can you (this might sound slightly weird) open a fish oil pill and rub that onto the face for the same effect? Or are the fish oil molecules too big for the skin to soak in? I have extremely dry skin so I am not too worried about pimples as a result. Do you suggest using OILS over lotions or creams for very dry skin-or do diff. oils react diff. to diff. skin?
