Face Cream

I'm thinking of using a night cream for my face. I think I need to seriously get into the habit of putting a face cream. For now, I am using 3-step skin care from Clinique. Is it true that the collagen face cream can make you look younger? If it is true, I wanna use one. I just want my face to stay young as it is... I don't believe I look older than my age, really... although somebody thought so. And I know I need to take care of my skin. And enjoy it while it's still young and firm.
