Sensitive skin, is there a way to improve it?

hello.

I am a user who struggles with home care because of my typical sensitive skin that easily turns over even with the slightest stimulation.

I've tried using cosmetics that I consider gentle and even changed my washing method, but my skin inevitably turns red and stings during seasonal changes or when I'm tired, and I still suffer.

I was hesitant to make the decision, as I'd searched online and found that sensitive skin could actually be toxic if treated incorrectly. However, I felt that home care alone was limited, so I decided to consider systematic management.

What treatments or treatments should I consider for sensitive skin to strengthen its barrier and return it to a healthy state?

I was wondering if there is a program specifically for sensitive skin that can control dryness and redness without causing too much irritation to the skin.

Please reply!
