  intro: "Glow isn't a product. It's what happens when light bounces off a smooth, hydrated surface. When that surface is covered in a backlog of dead cells, or depleted of water, or sitting behind a compromised barrier, light scatters instead of reflecting — and you look dull. The fix is mostly about removal and retention: exfoliating the surface regularly enough to keep it smooth, hydrating it adequately so it stays plump, and staying consistent enough that the skin doesn't have to catch up. Vitamin C is useful. AHA is useful. But both are useful in the right cadence, not at maximum strength every night. Below is the full library — what works, why it works, and how to avoid making dullness worse while trying to fix it.",

Dull skin scatters light — usually because the surface is rough (accumulated dead cells), depleted (dehydrated), or both. It's not a skin type; it's a surface condition.
