My skin has become more sensitive because it's spring. How should I take care of it?

Lately, my skin has become incredibly sensitive, which has been a concern. It easily turns red and breaks out in pimples from even the slightest irritation, and I feel frustrated every time I look in the mirror. Changing my face wash and cosmetics doesn't seem to make much of a difference, and I'm confused as to whether it's my lifestyle or an internal issue. I read online that laser treatments, peels, and skin boosters are good for alleviating skin problems, but I'm curious if they're actually safe for sensitive skin. Is external care alone enough, or should I also consider internal factors like diet and hormones? If you've tried dermatological treatments, please share which methods you found most helpful, and any lifestyle habits that you find effective in calming your skin. It would be incredibly helpful.
