How do you take care of your skin condition in dry weather like these days?

I have extremely dry skin and sensitive skin, so these days, when the weather is dry and the fine dust attack is severe, managing my skin condition is my biggest concern. Because it's so dry, I use an ampoule with hyaluronic acid, an atobarrier cream, and when it's severe, I add a drop of oil to it to manage it, but it's still dry. When it's dry, it itches, and when it itches, my skin turns red and because it's sensitive, it itches even more, and it's a vicious cycle. To manage my skin condition, I use a modeling pack regularly and pay attention to my water intake, but why is my skin condition so bad?

Those of you who are good at taking care of your skin condition, please share some tips.
