What are the key home care methods that can be maintained even in a busy daily life?

With frequent visits to the dermatologist becoming increasingly difficult these days, interest in home care methods has grown. I've heard that consistent, basic home care is more important than complex, multi-step routines. I'm curious if simply following basic home care methods like cleansing, moisturizing, and sun protection can stabilize skin condition. I've heard that when skin becomes sensitive, less irritating home care is more important than over-treatment, but I'm also unsure about the criteria for adjusting home care. I'd like advice on what factors I should consider to find the right home care method for me, and how I can adapt my home care regimen based on the season and my skin condition.
