I do not have any other Vincent Longo products, I got this just to use under my normal makeup.  It works as a very light moisturizing base, I did notice a difference that my powder went on smoother than normal (I don't use foundation).  The one drawback of this is that I have somewhat dry skin so if I use only this, it isn't enough of a moisturizer.  I have found that if I alternate my regular moisturizer and this that is works perfectly.  I have also used it over my regular moisturizer and it works well like that also.
