Home care method, is this the right way to do it?

As I've been focusing on skincare lately, I've naturally become more curious about home care methods. I'd like to know if washing and moisturizing alone are enough on busy days, or if there are any home care methods that I absolutely must follow, even if only minimally. I'm also wondering how many times a week I should use a sheet mask or exfoliate. Also, on days when my skin is sensitive, should I stick with my existing home care routine, or should I reduce my product use? Has anyone noticed any skin improvement with just home care methods that can be consistently used at home, without resorting to a salon? If you have any home care methods that have proven effective, please feel free to share them.
