How did you fix your broken skin barrier? Need real experiences + product recs.

My skin barrier feels completely damaged right now my face burns when I apply even basic products, feels tight and dry in some areas, gets oily in others, and overall just looks irritated. I have dry to combination skin, which makes it harder to figure out what to use. I also have acne marks that I want to fade eventually, but I’m not sure what is safe to use while my barrier is damaged. For anyone who has gone through this, I’d love to know what actually worked for you the products you used, the kind of routine that helped, anything that suited dry–combination skin, and whether diet or hydration made a difference. How long did it take for your barrier to heal, and when did you safely add treatments for acne marks? Also curious about what I should completely avoid right now. Real experiences would help me so much because online advice is all over the place.
