I've been using NIVEA’s CELLular Anti-Age Concentrated Skin-refining Serum in conjunction with NIVEA’s CELLular Anti-Age Facial Day Cream SPF15 for the past month. It is definitely a winning combination. As always, I love the familiar Nivea smell, bringing back wonderful childhood memories. This light feeling formulation is non-greasy, but really hydrating, and definitely made a huge difference in the texture of my skin. My skin really feels much more hydrated, and even my wrinkles seem to appear less visible. At my age, that is really a huge advantage, as my kids are at the age of realizing mommy isn't the beautiful model they saw through their "my mom is my hero" eyes any more. With Nivea, I can be that beautiful model mommy for a while longer.....I would definitely recommend Nivea Cellular Anti-Age Concentrated Skin-refining Serum to all my friends - especially the ones with teenage children. ;-)
