  intro: "Dehydration is a water question, not an oil question. Oily skin can be dehydrated. Dry skin can be hydrated. The two diagnoses are independent, which is why treating dehydration with richer creams alone rarely works. What the skin needs is water retained in the upper layers — held there by humectants, sealed in by occlusives, and not stripped out by a cleanser that's doing too much. The tight-after-cleansing feeling, the dull cast in certain lighting, the fine surface lines that disappear when you press a damp finger over them — these are dehydration markers, not ageing markers. Below is everything we've published: the techniques, ingredient primers, and routine adjustments that make the difference.",

Drinking more water doesn't fix it. Retaining water at the skin surface does.",
