  intro: "Barrier damage is usually self-inflicted. A few weeks of too many actives, too much exfoliation, or the wrong cleanser — and the skin starts telling you about it in the most inconvenient ways: stinging where it never stung before, redness that flares with products that used to be fine, sudden breakouts on skin that was otherwise clear. The stripping signs are reliable. The fix is also reliable: stop almost everything, start almost nothing, and give your barrier four to eight weeks to close. Centella asiatica, ceramides, and a single gentle moisturiser are the toolkit. Below is the full library on what barrier damage is, what caused it, and what the reset actually looks like in practice.",

    body: "The skin barrier — technically the stratum corneum — is the outermost layer of skin: a tightly-packed structure of dead skin cells and lipids (ceramides, cholesterol, fatty acids) that keeps moisture in and irritants out. When it's compromised, the face becomes reactive, tight, prone to flushing, and suddenly intolerant of products it handled fine before. It's a mechanical problem, not a skin-type problem, and it heals with time and the right inputs.",
