Does my skin good!

After 3 weeks of testing here my Résumé:
Since my skin has always been rather dry, I have tried many creams daytime and night creams. And they are very different expensive! Now I have arrived at the Nivea VITAL, which usually cost around 8 euros, so inexpensive.
The regenerating night cream is to provide new strength and regeneration. I have the impression that it does so. My sensitive skin, this night cream very well tolerated, it leaves a pleasant evening, smooth feel, although I have to use a fairly lush lot of it to feel this positive feeling. The cream is absorbed quickly without it leaves a greasy film with me. My skin feels soft and luscious.
Whether it really regenerates my skin?
This question I can not answer. Not even what the valuable calcium contributes to well-being.
I'll try for a longer period in the hope that it will be my time cream.
