Sensitive skin that changes with each season... Looking for some great skin care tips!!

This morning, after washing my face, I looked in the mirror and was surprised to see that the area around my nose and cheeks was particularly red.

In the past, no matter how tired I was, I would quickly recover by just applying basic skincare, but now my skin is so sensitive that it quickly reacts to even the slightest irritation...

I don't take care of my skin and it keeps getting worse, so I feel really upset and stressed when I look in the mirror.

Even though I apply a lot of moisturizing cream or soothing ampoule that is said to be good for my skin, it doesn't get absorbed properly and feels like it's just on the surface, so I worry more and more every night.

My skin condition worsens, especially on days with high levels of fine dust or wind. My sensitive skin has become so sensitive that I'm at a loss as to how to properly care for it.

Even the basic products I used to use are now stinging my face, so I'm considering clearing out my vanity. I'm diligently searching for products with the gentlest ingredients, but I'm afraid of applying them directly to my face, so I'm hesitant to try anything new. Anyone with sensitive skin like mine suddenly developed this sensitivity? How do you take care of it?

If you have any recommendations or special skin care routines that help soothe your skin without irritation, could you share them with us?
