What's an excellent moisturize for dry sensitive skin?

I've been using Eucerin and Cetaphil for my very dry skin (on my face) with pretty good results (though admittedly I really need to make moisturizing a habit which is challenge at my advanced age). Just wondering if I need to keep experimenting with different brands and if so, which ones? I prefer something that will calm redness and truly moisturize, something for sensitive skin and something that is fragrance free. Any other tips for making the most of my moisturizer would be greatly appreciated.
