I have been using NIVEA CELLular Anti-Age Serum for 2 weeks now and I can already see a difference in the overall condition of my skin. It looks smoother, the pores look finer, and the lines around the eyes are softer. I have been applying it morning and night and although I tend to have combination/oily skin and never use any creams at night, I had no experience of greasiness at all. I am very happy using this product and will continue to buy this for myself in future.
