Is there a way to strengthen the skin barrier this season?

As the weather gets much colder, it seems my skin is the first thing to notice the change. I didn't really feel the dryness during the summer, but now I can feel it deep down. I think strengthening the skin barrier during this season is the fundamental way to make the skin healthy. I believe that washing my face, applying sunscreen properly, cleansing thoroughly, getting enough sleep, exercising regularly, and maintaining healthy eating habits are all related to strengthening the skin barrier. However, it seems difficult to stick to all of them. My skin tends to be dry and sensitive, so I would appreciate recommendations for skincare products—such as essences, ampoules, or creams—that could help strengthen the skin barrier.
