Sensitive skin. I have a lot of concerns.

Lately, every morning, when I wash my face and look in the mirror, my face is flushed and irritated. I used to be fine with just anything, but I'm becoming more and more cautious about choosing even my basic skincare products. I used a famous essence my friends recommended, but it turned out bad, and I had a hard time. That's when I realized: I have sensitive skin, after all. When I get home from work, I'm anxious about even removing my makeup, worried that it might irritate my skin. I've been switching to gentler products, from cleansing oils to foams, but finding a product that works is like searching for a needle in a haystack. I've even tried several bottles of cica cream, which is supposed to be good for soothing, but it only has a temporary effect, so I need a more fundamental solution. What should I use for my sensitive skin? Whenever the wind gets even slightly chilly or the fine dust levels are high, I get an itchy, burning sensation, and I'm afraid to even go outside. Some say a cosmetic diet is the answer, while others say layering is better. I'm having a hard time deciding. I have sensitive skin like mine. For those of you who are concerned about this, what is the order of care after washing your face?
