I don't think I've ever written a skin care routine. I don't write these because I change it a lot and I'm not consistent with products I use. However, winter is always a problematic season for all skin types and we need to pay extra attention to our skin. As I mentioned I'm not good with 'routines', I'll write down some products I really like during this season and some tips I have to maintain a good skin care.
I also read this moisturizer guide "The best face moisturizer"* that emphasizes the importance of using one. They also explain everything you need and why you need it in a moisturizer and also what do you need for each skin type. What I love the most is how they actually did a contest between more than 200 moisturizers so pick the number one for day and night time and also gave some other options (find out which ones won the battle in the given link).
