  intro: "The acid mantle is one of those things that sounds clinical but behaves like common sense once you understand it. It's a film — naturally slightly acidic — that sits on the outermost surface of body skin. When that film stays intact, skin tends to feel balanced, comfortable, not stripped after a shower. When a cleanser disrupts it repeatedly, skin can feel tight for hours, or rough against fabric by evening. Most people have experienced that feeling. Fewer know what caused it.",

    body: "The acid mantle is a thin film on the skin's surface made up of sebum, sweat, and natural moisturising factors. It sits at a slightly acidic pH — roughly 4.5 to 5.5 on most body skin. That mild acidity supports the environment skin's natural microorganisms prefer. When a highly alkaline cleanser disrupts this film repeatedly, it can take hours to re-establish, and skin often signals the disruption as tightness or a rough, tacky surface feel.",

    { m: "Neutral pH cleansers are always safest.",
      t: "Skin's natural surface is slightly acidic — not neutral. A cleanser at pH 7 (neutral) can still shift the surface environment. Closer to 5–5.5 tends to feel more comfortable for most body skin." },
    { m: "If skin doesn't feel tight, the mantle is fine.",
      t: "Disruption doesn't always announce itself through tightness. Some people notice roughness, pilling of moisturiser, or products absorbing differently — all worth reading as signals." },

      t: "Many standard gentle body washes fall in a fine range. 'pH-balanced' on a label is a marketing phrase — it's worth actually knowing the number, or choosing formats known to lean gentle." },
