  intro: "In the fifties, the skin's constitution settles into something recognisably different from what came before. Menopause shifts the hormonal baseline. Lipid production drops further. The barrier becomes the central concern — not as a problem to solve but as a priority to tend. Retinol is still relevant but the retinaldehyde question arrives. Sun protection is not yet a habit to check; it is the non-negotiable anchor. Below is everything we've published on the subject.",

    body: "Menopause marks a hormonal shift that the skin registers directly: oestrogen supports collagen synthesis, sebum production, and moisture retention, and its decline changes all three. Cellular turnover slows to roughly 50–60 days. The skin barrier becomes more permeable, meaning water escapes more easily. SPF has now accumulated two to three decades of deferred returns. Retinol remains the most evidence-backed active, but tolerability changes and alternatives deserve consideration.",
