Skin barrier damage I am having such a hard time because of this. What should I do?

Skin barrier damage They said it could be because of that. It used to be fine, but suddenly Skin barrier damage Now that symptoms have appeared, I don't know which products to use, and even the skincare I used to use seems to be irritating. Do you happen to know? Skin barrier damage For those with experience, I am curious to know how you recovered. Please advise whether regenerating creams or soothing ampoules are helpful, or if dermatological treatment is necessary. I would be extremely grateful if you could share any products or routines that are safe for sensitive skin!
