Please recommend a way to care for sensitive skin ㅠㅠ

Because I have sensitive skin, it reacts easily to even the slightest irritation, so I always worry about taking care of it. ㅠㅠ When the season changes or I change my cosmetics even a little, my skin stings and turns red quickly. ㅜㅜ When it's severe, it even itches, making daily life uncomfortable. Even if I carefully check the ingredients in cosmetics for sensitive skin, there are many cases where they don't suit me when I actually use them, so trying new products is burdensome. If I minimize my skincare steps to reduce irritation, the dryness actually gets worse. Finding a way to take care of my sensitive skin is my biggest challenge these days. ㅠㅜ Is there a good way?
