A hypoallergenic home care routine for sensitive skin?

hello.

These days, my skin quickly turns red if my condition is even slightly off, and my skin is so sensitive that it stings even if the ingredients are slightly strong, so I'm really scared of changing even one basic product.

I think that home care that strengthens the skin barrier, even at home, is really important.
I'm trying to find my own home care method that is effective while minimizing irritation.

If you have extremely sensitive skin like mine, what kind of home care do you usually do?
From cleansing to moisturizing, I'd like to know some home care tips specifically for sensitive skin.

I can't use just any pack sold on the market, so if you have any effective home care products or skin care habits that soothe my skin without irritation, please recommend them.
