This is the first serum that I have tried. I have used it every morning under my moisturizer for 2 weeks. The smell is good, but mixed with my other Nivea product which smells different, it is not completely pleasant. It definitely makes my skin feel softer and better, but I cannot see any visible difference. Perhaps my winkles are not that big (I am +40!). Or perhaps the lighting in my bathroom at 5:30am is rather poor! I have been using it on my hands at night however & can really notice the difference - it has reduced the fine lines and feels super luxurious when you put it on.
It has been great to try (thank you Nivea!) because I have read so much about how fabulous serums are. In my personal view I would prefer a one-stop-product rather than putting on 2 products. I always need something with an SPF & I would prefer one scent rather than a mixture. But I will keep using it until it is finished, because I don't think you can always judge a product in only 2 weeks.
