What can I do about my sensitive skin that gets worse every time the seasons change?

This morning, after washing my face, I looked in the mirror and was really upset because my whole face was flushed. I used to hear a lot of compliments about my skin, but these days, even the slightest fatigue or weather change causes breakouts. My biggest concern is my sensitive skin. I've tried using soothing face masks and switching to a gentler base, but my skin still feels itchy and sensitive. I used to be fine with anything I put on, but now I have to carefully choose every ingredient, and it's almost scary to look in the mirror. It's so frustrating to not know where to start with sensitive skin care. Covering up the redness with makeup every morning is limiting, and it feels like it's irritating my skin even more, which makes me depressed. Do you have any tips for overcoming your sensitive skin, such as a skincare routine or a gentle cleansing method? I'd really appreciate it if you could share your experiences.
